3.5L V6 VQ35DE
Petrol
Check this by observing the transmission engagement: | Detail: On a test drive, ensure the transition between gears is smooth without flaring or hesitation. In the R50, it is common to consider that the automatic transmission can show signs of age if the fluid has not been serviced regularly.
While driving, listen carefully for suspension clunks: | Detail: The front suspension components, particularly the sway bar links and bushings, may show signs of wear given the age of these vehicles. Checking for uneven tyre wear is a good way to assess if the front end needs some love.
Check this by examining the cooling system: | Detail: While the engine is cold, inspect the coolant overflow bottle and radiator cap. It is wise to look for signs of oil contamination or rusty coolant, as the VQ35DE can be sensitive to cooling system health.
While idling in park, observe the RPM stability: | Detail: If the idle fluctuates noticeably, it could suggest a dirty throttle body or a tired Mass Air Flow (MAF) sensor. These are often manageable tasks for a home mechanic but worth noting during your inspection.
Usually the time to ensure the spark plugs have been attended to, as they are a bit of a process to reach on the V6 engine.
A common point to review the condition of the radiator and any ageing rubber cooling hoses to prevent potential overheating.
Prioritise regular engine oil and filter changes using high-quality synthetic oil to keep that V6 running smoothly.
Keep an eye on the transmission fluid colour; it should ideally be a nice bright red, not burnt or dark brown.
Check the brake pads and rotors regularly, as these are heavy vehicles and work their braking systems quite hard.
Clean the Mass Air Flow sensor periodically to ensure the engine runs as efficiently as possible.
Inspect the CV joint boots for any tears, as replacing these early can save you from a larger repair bill later.
Estimated repair costs if issues arise
If the engine check light indicates a knock sensor fault, the intake manifold needs to be removed to access it. Depending on the car's history, you might eventually need to budget for this deeper engine bay labour.
If the ride feels a bit wallowy or you hear rattles over speed bumps, it is common to consider replacing struts and bushings. If this component needs attention in the future, it will greatly improve the comfort of your ride.
As these vehicles age, the plastic tanks on the original radiators can become brittle. If this needs attention, planning for a new radiator is a sensible bit of preventative maintenance for your cooling system.
