2.5L VQ25DD (Neo Di) - RWD
Petrol
Observe the idle quality while in 'Park' and 'Drive'. The VQ25DD engine uses direct injection, so keep an ear out for any hesitation or roughness which might suggest the fuel pressure regulator or carbon buildup requires attention.
Listen for a faint 'rattle' coming from the front of the engine bay on a cold start. This is a good way to check the timing chain tensioner status, which is something to be aware of on high-mileage VQ engines.
Check the transmission health by feeling for smooth gear changes under light acceleration. The automatic transmissions in the M35 can sometimes be sensitive to old fluid, so ensure there are no abrupt jerks when shifting through the gears.
Inspect the rear suspension components and listen for clunks while navigating speed bumps or uneven pavement. Being a heavier estate vehicle, the rear bushings can naturally wear over time.
Usually the point where cooling system components like the radiator or hoses might start showing their age.
Consider having the suspension arms and ball joints assessed for natural wear and tear.
A good time to review the condition of the fuel pump and ignition coil packs to ensure consistent engine performance.
Check the engine oil level and clarity; these V6s prefer high-quality synthetic oil changed regularly.
Inspect the coolant reservoir for any signs of discolouration or debris.
Verify that the battery is held securely and the terminals are free from corrosion.
Test all electronic accessories, especially the air conditioning, as these systems appreciate regular use.
Check the tyre tread depth and look for even wear across the width of the tyres to ensure proper alignment.
Estimated repair costs if issues arise
Because the VQ25DD is a direct-injection engine, if you notice poor fuel economy or stuttering later on, you might eventually need to budget for a fuel system cleaning or component refresh.
As these cars have been on NZ roads for a while, the suspension bushings can eventually perish. If the handling starts to feel a bit vague, setting aside some funds for a suspension refresh will help restore that sharp handling.
In cars of this age, it is common to consider a preventative cooling system refresh. Replacing the radiator and thermostat ensures you have peace of mind during long summer trips.
