3.5L (VQ35DE) - Base/Track/Touring models
Petrol
Test drive task: Find a quiet, flat stretch of road and listen for a metallic rattling noise during low-speed deceleration. | Description: It's common for these to experience worn syncromesh on the 5th and 6th gears in manual models, so shifting smoothly through every gear is a great way to verify the transmission's health.
Check this by: With the engine at operating temperature, perform a slow U-turn at full lock while listening for clicking sounds. | Description: The CV joints can sometimes show signs of age on higher-mileage examples; keeping an ear out for any clicking will help you gauge the condition of the drivetrain.
While parked: Operate the electric window switches several times, noting the speed and smoothness of the travel. | Description: The window regulator motors are known to work hard over the years, and a sluggish window could indicate the motor is nearing the end of its service life.
Inspect this by: Checking the coolant reservoir for any signs of 'milky' residue or oily film. | Description: While relatively robust, these engines have a high thermal output, and monitoring the cooling system's health is a sensible step when evaluating a car of this vintage.
Consider a full fluid flush, including transmission and differential oils, to keep the drivetrain feeling crisp.
It is often a good time to inspect the condition of suspension bushings and engine mounts as they naturally settle over time.
The cooling system, particularly the radiator and hoses, should be reviewed as a preventative measure for long-term reliability.
Regular engine oil and filter changes every 7,500km to keep the VQ35DE happy.
Keep an eye on tire pressure and tread wear, as the Z33’s suspension geometry can be sensitive.
Periodically check and clean the mass airflow sensor to maintain smooth throttle response.
Inspect the brake pads and rotors during every service, given the performance nature of the vehicle.
Ensure the cabin air filter is replaced annually to keep the interior environment fresh.
Estimated repair costs if issues arise
Future Budget Planning: Depending on how the car has been driven, you might eventually need to budget for a clutch refresh. It's a significant job that usually involves removing the transmission.
Future Budget Planning: Over many years on NZ roads, the rubber bushings may begin to show their age. Replacing these with poly bushes can sharpen up the handling significantly.
Future Budget Planning: These electronic sensors can occasionally fail as they age, which might cause an engine light or rough idle. It is a common maintenance item for this engine platform.
