While accelerating gently, check for any 'shudder' or hesitation. In higher-mileage examples, the CVT transmission can sometimes show signs of wear, so ensure transitions between gears are seamless.
Check this by turning the steering wheel full lock in a quiet parking lot. Listen for any clicking or knocking sounds, which may indicate that the Constant Velocity (CV) joints are reaching the end of their service life.
Monitor the engine temperature gauge and heater performance while idling. Older 1NZ-FE engines can occasionally have cooling system fatigue, and a poorly performing heater core can be a sign of long-term coolant neglect.
During your inspection, check the condition of the door seals and look for any dampness in the footwells. As these vehicles age, the weather stripping can lose its elasticity, occasionally allowing moisture into the cabin.
Usually time to inspect the serpentine belt and verify if the transmission fluid has been serviced.
A common point where engine mounts might start showing signs of vibration and ignition coils may need testing for optimal fuel efficiency.
Consider having the suspension bushings and struts assessed to ensure the ride quality remains comfortable and safe.
Stick to a 10,000km oil change interval using high-quality 0W-20 or 5W-30 synthetic oil to keep that 1NZ-FE engine running smoothly.
Check your transmission fluid condition; while often labelled as 'sealed for life', a drain and fill every 60,000km can significantly extend CVT longevity.
Keep an eye on the engine air filter and cabin filter; replacing these regularly keeps the engine breathing well and the interior fresh.
Ensure the coolant is flushed periodically to protect the aluminium components of the cooling system from corrosion.
Regularly inspect your tyre tread depth and pressure, as the Allion’s economy-focused chassis performs best with balanced, well-maintained tyres.
Estimated repair costs if issues arise
If you notice the transmission feeling sluggish or jerky, it is worth setting aside funds for a professional fluid exchange and diagnostic scan to ensure long-term reliability.
Depending on the car's history on rougher NZ roads, you might eventually need to budget for replacing worn suspension control arm bushings if you notice any knocking over bumps.
If the engine develops a slight misfire or feels down on power, it is common to consider replacing the ignition coils, which is a straightforward maintenance task for this engine.
