The Infiniti QX80 is one of the most popular full-size luxury SUVs in the UAE. It carries big families, tows boats to the marina, crosses the desert on weekends and sits for long periods in traffic with the AC on full. That is exactly why Infiniti QX80 engine overheating is a regular complaint in Dubai workshops, especially from June to September. The cooling system on a large SUV is designed with a safety margin, but in 45°C to 50°C heat that margin is almost used up before the car has even moved. A worn part that would go unnoticed in a cooler country is enough to push the temperature gauge up here. If you want the wider picture first, our guide on how Dubai heat damages car engines explains what this climate does to every engine.

This guide explains why the QX80 overheats, which parts fail and why, how a proper repair is carried out, and how to prevent the problem from coming back. It is written for owners of the V8 QX56 and QX80 as well as the new twin-turbo V6 QX80, because the two engines do not overheat for the same reasons.

Which Infiniti QX80 Do You Have? V8 and Twin-Turbo V6 Cooling Systems

Before looking at causes, it helps to know which engine is under the bonnet. The cooling system layout, the extra heat loads and the most likely faults all depend on it.

Model	Model years	Engine	Gearbox	Cooling notes
Infiniti QX56 (Z62)	2011 to 2013	5.6 V8 VK56VD, direct injection with VVEL	7-speed automatic	Engine-driven fan with viscous clutch, radiator also cools the gearbox fluid
Infiniti QX80 (Z62)	2014 to 2024	5.6 V8 VK56VD, around 400 hp and 560 Nm	7-speed automatic	Same layout as the QX56, updated over several facelifts
Infiniti QX80 (Z63)	2025 onwards	3.5 V6 twin-turbo VR35DDTT, 450 hp and 700 Nm	9-speed automatic	Turbo charge-air cooling added to the front cooling pack, active grille shutters

The V8 QX80 is built on the same platform as the Nissan Patrol Y62 and uses the same VK56 engine family, so many cooling faults are shared between the two. Our Nissan Patrol overheating guide is useful reading if you also run a Patrol. The 2025 QX80 is a different machine. The V8 was replaced by a twin-turbocharged V6, which makes more power from a smaller engine but also produces concentrated heat in the turbochargers that the cooling system has to deal with.

How the QX80 Cooling System Keeps the Engine at Temperature

An engine only turns about a third of the energy in its fuel into movement. Much of the rest becomes heat, and on a 5.6 litre V8 working hard in Dubai summer, that is a large amount of heat to get rid of. The cooling system does this with five jobs that have to happen at the same time.

First, the water pump moves coolant through the engine block and cylinder heads, where it absorbs heat. Second, the thermostat controls the temperature by deciding how much of that hot coolant goes to the radiator. Third, the radiator passes the heat from the coolant into the air flowing through its fins. Fourth, the cooling fan makes sure air keeps flowing through the radiator when the car is moving slowly or standing still. Fifth, the radiator cap and expansion tank keep the system under pressure, which raises the boiling point of the coolant well above 100°C.

When any one of these jobs is done badly, the others cannot make up the difference for long. That is why proper overheating repair always looks at the whole system, and why a radiator and coolant service is more than topping up the reservoir.

There is one more thing every QX80 owner should know. The dashboard temperature gauge is buffered. It is designed to sit still in the middle across a wide range of real coolant temperatures, so the driver is not worried by normal changes. The downside is that by the time the needle moves visibly towards hot, the engine is already well above its normal operating temperature. A rising needle on a QX80 is never a minor warning.

The sections below group the causes of QX80 overheating by which of these five jobs has failed.

Airflow Problems: Fan Clutch, Fan Blade and a Blocked Cooling Pack

If your QX80 overheats in slow traffic, in drive-throughs or while idling with the AC on, and then cools down once you are moving at speed, the problem is almost always airflow. At highway speed, the air rammed through the grille cools the radiator by itself. At walking pace, the cooling fan has to do all the work.

QX80 Viscous Fan Clutch Failure

The V8 QX56 and QX80 use a large engine-driven fan mounted on a viscous fan clutch. Inside the clutch is a thick silicone fluid and a heat-sensitive valve. When the air coming through the radiator is hot, the valve lets more fluid into the working chamber, the clutch locks up and the fan spins faster to pull more air. When the engine is cool, the clutch slips so the fan does not waste power and make noise.

Over time, and much faster in UAE heat, the silicone fluid breaks down or leaks out. The clutch can no longer lock up, so the fan spins slowly even when the engine is hot. On the road you will not notice anything. In traffic in August, the gauge starts to climb and the AC gets weaker at the same time, because the condenser is not getting enough air either.

Signs of a worn fan clutch include a fan that spins freely by hand on a cold engine with almost no resistance, oily streaks around the clutch body, and no noticeable roar from the fan when the engine is hot and idling. A fan clutch replacement on the QX80 is a straightforward job for a workshop, and it is one of the most common fixes for QX80 overheating in traffic.

Cracked Fan Blades and Missing Shroud Seals

The fan blade itself is plastic. Years of heat and constant load cause cracks around the hub and at the root of the blades. A cracked blade is dangerous because a piece can break off at high RPM and damage the radiator, so the fan blade should always be checked when the fan clutch is changed.

The fan shroud matters just as much. It forces the fan to pull air through the whole radiator rather than around its edges. A shroud that is cracked, missing clips, or missing its rubber seals after an earlier repair can reduce cooling at idle more than most owners expect.

Sand and Debris Packed Between the AC Condenser and Radiator

At the front of the QX80 there is a stack of heat exchangers: the AC condenser at the front, the radiator behind it, and on the 2025 model, the turbo charge-air cooling as well. Fine sand, dust, leaves and insects collect in the narrow gap between these cores. From the outside the radiator can look clean, while the middle of the stack is blocked like felt.

This is one of the most common hidden causes of QX80 overheating in the UAE, and it is especially common on cars used for desert driving. Washing the grille from the front does not fix it and can push debris deeper. The correct method is to clean the stack from the engine side outwards with low-pressure water or air, sometimes with the condenser loosened to reach the gap.

Active Grille Shutters on the 2025 QX80

The new twin-turbo V6 QX80 has active grille shutters. These close at cruising speed to reduce drag and save fuel, and open when the engine needs more cooling air. If the shutter motor fails, its linkage breaks, or sand jams the vanes in the closed position, the radiator loses a large part of its airflow. Because the car is new, this is something to check whenever a 2025 or later QX80 runs warmer than usual.

Coolant Flow Problems: Water Pump, Thermostat and Hoses

If airflow is good but coolant is not moving properly through the engine and radiator, the engine heats up under load even at speed.

QX80 Water Pump Leaks and Worn Impellers

The water pump sits at the front of the engine behind the fan. Inside, a seal keeps coolant away from the pump bearing. When that seal wears, coolant weeps out of a small drain hole on the pump body. The first sign is usually dried blue or white crust on the front of the engine, a faint sweet smell after driving, or a coolant level that drops slowly over weeks.

A water pump can also fail without leaking. Corrosion from old coolant can erode the impeller blades so the pump still turns but moves less coolant, especially at higher RPM. The engine then runs hotter on long climbs, on the highway at speed, or when towing. Our guide to water pump failure symptoms explains these signs in more detail, and they apply to the QX80 as well.

Replacing a QX80 water pump means removing the fan, fan clutch and shroud first, so it is sensible to inspect or renew the fan clutch, drive belt and thermostat in the same job. On high-mileage V8s that also need a timing chain kit, many workshops replace the pump at the same time because the front of the engine is already open.

Thermostat Stuck Closed or Partly Open

The thermostat is a wax-controlled valve. Below its opening temperature it keeps coolant inside the engine so the engine warms up quickly. Above it, the valve opens and coolant flows to the radiator. A thermostat that sticks fully closed causes rapid overheating within minutes. One that only opens part of the way is harder to spot, because the car runs normally in light driving and only overheats under load or in the afternoon heat.

The quality of the replacement part matters. Original Nissan and Infiniti thermostats include a small air-bleed valve that lets trapped air escape from behind the thermostat. Some cheap copies do not have it, or have it in the wrong position, which can trap air and cause overheating after a repair that looked correct. The thermostat housing and its seal should be checked at the same time, as plastic and aluminium housings can crack or leak after years of heat cycles.

Collapsing, Swollen or Leaking Coolant Hoses

Rubber coolant hoses age from the inside. Heat and old coolant break down the inner lining until the hose becomes soft and swollen, or hard and cracked. A soft lower radiator hose can collapse under the suction of the water pump at high RPM, which restricts flow just when the engine needs it most. Heater hoses near the firewall and the small bypass hoses are also common leak points on older QX56 and QX80 models.

A good test is to squeeze the hoses when the engine is cold. They should feel firm and springy. Any hose that feels crunchy, spongy or bulges near the clamps should be replaced, and the clamps should be replaced with it.

Heat Rejection Problems: The QX80 Radiator

When the radiator itself cannot release enough heat, the QX80 overheats mainly at speed, on long climbs such as the roads to Hatta or Jebel Jais, and when towing.

Internal Blockage and Scaling

The QX80 radiator has an aluminium core made of many small tubes. Old coolant loses its corrosion inhibitors, and the metal surfaces start to corrode. The corrosion products, plus deposits from mixed coolant types or topping up with tap water, collect in the tubes and block them one by one. The radiator still looks fine from outside, but part of the core no longer carries hot coolant.

A workshop can find this by scanning the radiator face with an infrared thermometer when the engine is hot. A healthy radiator shows an even temperature drop from inlet to outlet. A blocked one shows cold vertical strips where tubes are no longer flowing. Flushing helps if the blockage is light, but a heavily scaled radiator needs to be replaced. Our article on the top car radiator repair reasons explains why waiting usually costs more.

Cracked Plastic End Tanks

The radiator tanks on each side of the core are plastic, crimped onto the aluminium core with a rubber seal. Constant heat cycling makes the plastic brittle. Hairline cracks appear around the hose necks and along the crimp line, and the radiator starts to weep coolant under pressure. Sometimes a tank cracks suddenly after the engine has already overheated, which can make it look like the radiator was the cause when it was actually the victim of another fault.

Plastic tanks cannot be reliably repaired with sealant or welding on a vehicle this heavy and this hot, so a cracked tank normally means a new radiator. Our Nissan Patrol radiator replacement guide covers the same decision on the sister vehicle, and our car radiator repair cost guide explains what affects the price.

When the Radiator Also Cools the Transmission

On the V8 QX56 and QX80, the automatic transmission fluid is cooled through a heat exchanger built into the radiator end tank. This means the radiator has to carry gearbox heat as well as engine heat. When you tow, climb or drive in sand, the gearbox gets hotter and so does the coolant.

It also creates a risk that owners should know about. If the internal transmission cooler inside the radiator fails, coolant and transmission fluid can mix. The earlier generation QX56 built a reputation for exactly this, with many owner reports of radiators leaking into the transmission and causing gearbox failure, so it is a known risk on this family of vehicles. Coolant in the gearbox destroys clutch packs and seals quickly. Warning signs include pink or milky transmission fluid, a coolant level that drops with no external leak, and harsh or slipping gear changes. If cross-contamination is found, the radiator must be replaced and the gearbox flushed and checked straight away, which is a job for proper gearbox repair. Read everything you need to know about gearbox repair in Dubai for the wider warning signs.

Pressure and Coolant Loss Problems

A cooling system can only work at high temperature if it holds pressure and stays full of the right coolant.

Radiator Cap and Expansion Tank

The pressure cap holds the system at a set pressure, which lifts the boiling point of the coolant far above 100°C. When the rubber seal on the cap hardens or its spring weakens, the system loses pressure, the coolant boils at a lower temperature, and steam pockets form in the hottest parts of the cylinder heads. The engine then overheats even though the radiator, pump and fan are all healthy. A cap costs very little compared with the damage it can cause, so it should be pressure tested at every cooling system inspection and replaced with every new radiator.

The plastic expansion tank also ages in the heat. Cracks along the seams or around the hose connections let coolant escape as vapour, often without leaving a puddle under the car.

Air Locks After Coolant Work

The V8 QX80 has a large cooling system with high points where air can collect. If the system is not filled and bled correctly after a coolant change, radiator replacement or water pump job, an air pocket can sit around the thermostat or in a cylinder head. The thermostat then does not feel the hot coolant, opens late, and the engine overheats. Other signs are a heater that blows cold at idle and gurgling sounds behind the dashboard. Vacuum filling equipment removes this risk and is the correct way to refill a system of this size.

Wrong or Mixed Coolant

Nissan and Infiniti specify their own long-life blue coolant, supplied pre-mixed. Topping up with green coolant, a “universal” coolant or plain water does not cause an immediate problem, but it dilutes the corrosion inhibitors and can create deposits that block the radiator and wear the water pump seal. Plain water also lowers the boiling point. If the coolant in your QX80 has changed colour, looks cloudy, or has particles floating in it, the system needs a full flush and refill with the correct coolant, not another top-up.

If your QX80 keeps losing coolant and you cannot find where it is going, our guide on why a car loses coolant but is not leaking explains every route the coolant can take.

Extra Heat Loads Dubai Puts on the QX80

Some QX80s overheat not because a part has failed, but because a weak part meets a heavy load. These are the conditions that most often reveal a cooling system that is close to its limit.

AC Load in Summer Traffic

The AC condenser sits directly in front of the radiator. Every unit of heat the AC removes from the cabin is released through the condenser, and that heated air then flows into the radiator. On a 47°C afternoon with seven people in the car and the AC on maximum, the radiator is breathing air that is already very hot. A slightly worn fan clutch or a partly blocked condenser that causes no trouble in winter is enough to tip the engine into overheating in summer.

The two systems affect each other in the other direction too. An overcharged AC system or a condenser clogged with sand runs at high pressure and dumps even more heat in front of the radiator. Many QX80 owners notice the AC getting warmer just before the temperature gauge rises, because the engine computer can reduce AC compressor load to protect the engine. That is why overheating diagnosis should include a car AC repair check. Our guides on car AC maintenance and the best time to check your car AC in Dubai explain how to keep both systems healthy before summer.

Towing Boats, Caravans and Horse Trailers

The QX80 is a popular tow vehicle in the UAE. Towing raises engine load, raises transmission fluid temperature and, on the V8, sends that gearbox heat straight into the radiator. Long climbs with a trailer in the afternoon heat are the hardest test the cooling system faces on the road.

When towing, keep the gearbox in a lower gear on climbs so the torque converter stays locked and produces less heat, avoid long periods at very low speed, and keep an eye on the gauge. If you tow regularly, the transmission fluid and coolant should be changed more often than the normal schedule. Tyres matter as well, because an overloaded or under-inflated tyre adds rolling resistance and heat. Our SUV tyre load index guide explains how to check that your tyres are rated for the load.

Dune Driving and Low-Speed Sand Work

Dune driving combines the worst conditions for cooling: high engine RPM, heavy load, low gears and almost no road speed, so there is little natural airflow through the radiator. Sand is also thrown up and pulled into the grille, the condenser and the fan shroud. A QX80 that is used in the desert even a few times a season needs its cooling pack cleaned from the inside much more often than a car used only in the city. Our guide on how to take care of your luxury car in Dubai’s harsh climate covers sand protection in more detail.

Turbo Heat on the 2025 QX80 V6

The twin turbochargers on the VR35DDTT run extremely hot under load. They are cooled by engine oil and coolant, and the compressed air they produce has to pass through a charge-air cooler before it enters the engine. That cooler adds another heat exchanger to the front of the car, competing for the same airflow as the radiator and AC condenser.

Two habits protect a turbocharged QX80. First, after a hard drive, a long climb or a desert session, let the engine idle for a minute or two before switching off, so oil and coolant can carry heat away from the turbochargers. Switching off immediately can cook the oil in the turbo bearings. Second, keep the front cooling pack clean, because a blocked charge-air cooler makes the engine pull ignition timing and run hotter. If the warning lights or engine noises change after a hot run, a qualified car electrician in Dubai can check the sensors and wiring that heat soak affects first.

Tuning also changes the picture. A remapped turbo engine or a modified V8 produces more heat than the standard cooling system was designed for. Any car modification that raises power should include a cooling upgrade, and it must stay within the car engine and exhaust modification rules in Dubai.

When the Engine Itself Is the Cause: Head Gasket and Internal Damage

Sometimes the cooling system is not the cause of the overheating but the place where an engine fault shows up. The VK56VD V8 has an aluminium block and aluminium cylinder heads sealed with multi-layer steel head gaskets. If the engine has been overheated badly in the past, the heads can warp slightly and the gasket can lose its seal between a combustion chamber and a coolant passage.

When that happens, combustion gas is pushed into the cooling system at very high pressure. The coolant is forced out of the expansion tank, air bubbles appear in the tank with the engine running, the upper radiator hose becomes hard even on a cold engine, and the engine overheats again and again no matter how many parts are replaced. Other signs are white exhaust smoke with a sweet smell, a coolant level that keeps falling with no visible leak, and milky residue under the oil filler cap.

Head gasket and cylinder head problems are almost always the result of an earlier overheat, not the starting point. That is why it is so important to stop driving when the temperature rises. These are also among the signs your car needs immediate engine service before a breakdown happens. Repair involves removing the cylinder heads, checking them for flatness and cracks, machining them if needed, and fitting new gaskets and head bolts, which is work for a specialist car engine repair workshop.

Infiniti QX80 Overheating Warning Signs

The temperature needle is the last warning, not the first. Most QX80 cooling problems give earlier signs if you know what to look for:

• The AC blows less cold in traffic and recovers once you start moving.
• The cooling fan sounds quieter than usual on a hot day, or does not roar when you first start a hot engine.
• The coolant level in the expansion tank drops between services.
• A sweet smell after driving, or dried blue or white crust on the front of the engine or around the radiator.
• The heater blows cold at idle, or there is a gurgling sound behind the dashboard.
• Steam or vapour from the front of the car after stopping.
• Transmission fluid that looks pink or milky, or gear changes that suddenly feel harsh.
• The engine feels down on power on hot afternoons, as the engine computer reduces power to protect itself.

If your QX80 also has a check engine light or rough running, our guide on engine misfire repair in Dubai explains how heat can affect ignition coils and sensors. Many of these early signs are also covered in our article on the signs your car needs a service that Dubai drivers usually overlook.

What to Do If Your QX80 Starts Overheating

When the needle starts to rise, switch the AC off straight away to remove the condenser heat from in front of the radiator. Then turn the heater to full hot with the fan on maximum. The heater core works as a small second radiator and pulls some heat out of the engine. It will be uncomfortable in summer, but it can buy the time you need to stop safely.

Pull over as soon as it is safe, put the gearbox in park, and switch the engine off if the needle is near the red zone or a warning message appears. Do not open the expansion tank or radiator cap on a hot engine. The coolant is under pressure and can spray out and cause serious burns. Do not pour cold water over the engine either, because the sudden temperature change can crack an aluminium cylinder head.

If the temperature rose quickly, if there was steam, or if the coolant level is very low once the engine has cooled, do not drive on. Arrange recovery instead. Our guide on how to choose the best roadside assistance service in Dubai is worth reading before you ever need it.

What Happens If You Keep Driving an Overheating QX80

Many owners try to “just make it home”. On a large aluminium engine, that decision can turn a small repair into a very expensive one.

As the temperature rises beyond normal, the engine oil thins and starts to break down, so bearings, camshafts and the timing chain lose protection. The VK56VD timing chain system depends on clean oil pressure to work correctly, and oil that has been cooked in an overheat wears the chain and its guides faster. That is why the oil must be changed after any serious overheat, using the correct grade. Book it through our oil change service, and see how to pick the right engine oil for your car for why the grade matters.

If the engine keeps running hot, the cylinder heads expand more than the block and can warp, and the head gaskets fail. Pistons can scuff the cylinder walls, and in the worst case the engine seizes. Our article on what causes an engine to seize explains how quickly this damage can happen. On the V8, the gearbox also suffers, because hot coolant means hot transmission fluid. A water pump or fan clutch repair is a small job. A cylinder head job or a gearbox rebuild is not.

How a Workshop Diagnoses QX80 Overheating

Replacing parts at random is the most expensive way to fix an overheating QX80. A thermostat, a radiator and a water pump can all be changed and the car can still overheat if the real cause was a fan clutch or a head gasket. Proper diagnosis follows the heat step by step, as explained in our article on professional engine diagnostics for modern cars.

A good workshop starts by talking to the owner. When does it overheat, at idle, on the highway, when towing, or only after a recent repair? That single answer narrows the cause more than any tool. Next, the technician connects a diagnostic scanner and reads live coolant temperature, fan-related data and stored fault codes, because the dashboard gauge hides the real number. Our guide on why regular car diagnostics prevent expensive repairs explains why live data is so valuable.

The cooling system is then pressure tested cold to find leaks that only appear under pressure, and the radiator cap is tested on its own. A combustion leak test checks the coolant for exhaust gas, which confirms or rules out a head gasket before anyone recommends major engine work. With the engine hot, the technician checks the fan clutch engagement, scans the radiator with an infrared thermometer to find blocked tubes, and measures the temperature on both sides of the thermostat to confirm it is opening. The water pump is checked for bearing play and weeping, the hoses for softness, and on the V8 the transmission fluid is checked for any sign of coolant. On the 2025 QX80, the active grille shutters and charge-air cooling are also inspected. Our comprehensive engine diagnostics guide walks through this approach in more depth.

Infiniti QX80 Overheating Repair: What the Fix Involves

Once the cause is confirmed, the repair is usually one of the jobs below, often combined, because cooling parts tend to age together.

A fan clutch replacement is the most common fix for overheating in traffic. The fan blade should be inspected for cracks at the same time and the shroud checked for missing seals. A cooling pack clean removes sand and debris from between the condenser and radiator, done from the engine side with the right pressure so the fins are not flattened.

A thermostat replacement should use an original or OE-quality part with the correct air-bleed valve, a new seal, and a properly bled system afterwards. A water pump replacement includes a new gasket, and it is good practice to inspect the drive belt, belt tensioner and idler pulleys while the fan is off.

A radiator replacement on the QX80 should always include a new pressure cap and a full coolant flush, and the thermostat is often renewed at the same time. On the V8, the transmission cooler lines are disconnected and refitted, so the gearbox fluid level must be checked and corrected afterwards. If the old radiator had an internal leak between the coolant and gearbox fluid, the transmission must also be flushed and inspected. Our radiator repair cost guide explains what drives the price of this job.

Hose replacement should include all aged hoses rather than only the one that failed, with new clamps. After any of these repairs, the system is filled with the correct Nissan and Infiniti coolant using vacuum filling equipment, then road tested and checked again hot.

If the engine has been seriously overheated, a compression test and leak-down test show whether the head gaskets and valves are still sealing. If they are not, the cylinder heads come off for inspection, machining and new gaskets. Larger jobs can be spread out with Tabby pay-later car repair.

How to Prevent QX80 Overheating in UAE Heat

Most QX80 overheating problems can be prevented with maintenance that matches the climate. Standard service schedules are written for average conditions, and Dubai is not average.

Renew the coolant every three to four years in UAE conditions, sooner if the car is used for towing or desert driving, and always with the correct Nissan and Infiniti specification. Old coolant is the root cause of many radiator blockages and water pump failures. Have the cooling pack cleaned from the engine side before every summer and after every dune season, because sand between the condenser and radiator builds up slowly and silently.

Ask for the fan clutch, fan blade, hoses, water pump and radiator cap to be checked at every service before the hot months. Follow a heat-adjusted schedule like the one in our UAE luxury car maintenance schedules guide, and if you are unsure what a full service should include, check our full car service checklist and the difference between a major and minor car service.

Keep the engine oil and transmission fluid fresh, especially if you tow. Heat breaks both down faster here, and on the V8 the gearbox and engine cooling are directly linked. Our article on why you need to change your car’s oil regularly explains what happens when oil is left too long.

Have the AC checked before summer, because an overcharged or blocked AC system makes the engine run hotter. On the 2025 QX80, let the engine idle for a short time after hard driving before switching off, to protect the turbochargers.

Finally, book a pre-summer car inspection in Dubai. It costs far less than a radiator or head gasket, and it finds weak parts before the hottest weeks of the year. Our engine inspection checklist shows what a proper inspection covers, and our general guide on preventing engine overheating in hot weather covers the everyday habits every driver should follow.

Buying a Used QX80 in the UAE: Checking for Past Overheating

The V8 QX80 is a common used purchase in the UAE, and a car that has overheated badly in the past can look perfect on a short test drive. Signs of a previous overheat include a brand-new radiator or water pump on a car with otherwise original parts, coolant residue on the engine, a coolant colour that does not match the Nissan specification, oil with a milky tint under the filler cap, and transmission fluid that is pink or cloudy.

A proper pre-purchase inspection should include a cooling system pressure test, a combustion leak test, live temperature data on a hot engine and a gearbox fluid check. Before you buy, run the car through our free VIN check UAE tool to see its history, and have it inspected at an independent car inspection centre. If the car is going for its annual test, our RTA testing centre page explains what is checked.
