Petrol
Check this by inspecting the door bottoms and wheel arches for any bubbling paint; in cars of this age, it is common to consider that moisture can occasionally get trapped, leading to surface corrosion.
While driving at low speeds, gently turn the wheel lock-to-lock to feel for any binding; the fourth-gen steering racks can sometimes develop wear over time, so listen for any unusual groaning.
Check this by observing the transmission fluid color and smell during a test drive; if the shifts feel lazy or hesitant, you might eventually need to budget for a professional service or potential valve body cleaning.
While sitting in the car, operate the power windows and door locks repeatedly; electrical connections in these models can sometimes experience fatigue, and it is helpful to ensure all switches respond consistently.
Usually the time to evaluate the state of the suspension bushings and ball joints for any play.
A sensible interval to confirm the health of the cooling system, including hoses and the radiator, to avoid overheating risks.
Consider having the timing chain guides and tensioners inspected, as these components have seen plenty of use by this stage.
Keep a regular eye on the engine oil level, as these 4.6L V8s appreciate being kept topped up with quality synthetic oil.
Flush the brake fluid every two years to ensure the pedal feel remains crisp and responsive for your safety.
Check the differential fluid during your annual service, as this is often overlooked but keeps the rear end running smoothly.
Clean the air filter intake regularly to ensure the V8 can breathe properly and maintain its legendary rumble.
Inspect the coolant concentration before winter hits to ensure the engine is protected against freezing, which is helpful even in milder NZ climates.
Estimated repair costs if issues arise
The composite intake manifolds on the 4.6L V8 can occasionally develop minor cracks or gasket leaks over time. If this happens, you might eventually need to budget for a replacement manifold and labor to ensure the engine runs at peak efficiency.
As the rubber bushings and struts age, you may notice the ride becoming a bit less composed. If you feel excessive road vibration or clunking, you might eventually need to budget for a refresh of the front control arms and shocks.
If the automatic gearbox starts to feel a little 'soft' in its shifting, a complete fluid and filter change can often work wonders. Depending on the car's history, you might eventually need to budget for this as a preventative measure to keep the transmission shifting cleanly.
