1.5L 1NZ-FE Petrol (FWD)
Petrol
Observe the idle speed while stopped in Drive. | Note: In cars of this age, the 1NZ-FE engine can sometimes develop a rough idle due to a dirty Idle Air Control valve or carbon buildup, which is a common maintenance item.
Perform several gear changes from Park to Reverse and Drive. | Note: Listen for any clunking or hesitation. While the automatic transmission is generally robust, it is worth checking the engine and transmission mounts for signs of wear which can lead to increased vibration.
Check the interior dashboard panels and switchgear. | Note: The WiLL VS features a very unique, complex interior design; ensure all power windows and A/C controls function, as some of the specific trim parts can be tricky to source locally in New Zealand.
Inspect the front strut towers and suspension components. | Note: Look for signs of oil weeping from the struts; as these vehicles are now getting on in years, the original suspension bushings may be showing signs of fatigue, affecting handling precision.
Consider replacing the serpentine belt and verifying the condition of the coolant hoses.
Check the condition of the ignition coils and spark plugs to maintain optimal fuel efficiency.
It is often a good time to have the transmission fluid refreshed and check for any minor oil seepage from the valve cover gasket.
Check the engine oil level and color; the 1NZ-FE appreciates regular, clean oil changes every 10,000km.
Verify the coolant is clean and bright pink to protect the longevity of the aluminum engine block.
Check the air filter condition to ensure the engine breathes well and fuel economy remains consistent.
Inspect the tyre tread for even wear to ensure the suspension geometry is still well-aligned.
Ensure the battery terminals are clean and tight, as stable voltage is important for the vehicle's electronic systems.
Estimated repair costs if issues arise
If the ride feels overly bouncy or you hear clunking over speed bumps, you might eventually need to budget for a suspension refresh. This ensures the unique handling of the WiLL VS stays sharp.
If the gear shifts feel a bit hesitant, a professional transmission fluid change can often improve smoothness. It's a proactive step to keep the gearbox happy for the long haul.
Depending on the car's history, you might eventually need to budget for replacing the radiator and hoses to prevent any overheating issues as the plastic components age.
