4.0L V8 Supercharged (AJ-V8) - High-performance grand tourer
Petrol
Observe the transmission carefully at low speeds. When accelerating gently, note if there is any 'shudder' or hesitation during gear changes, as these ZF 5HP24 transmissions can sometimes exhibit signs of wear in cars of this age.
Check the timing chain tensioners by listening closely to the engine bay during a cold start. A brief rattle might suggest that the early plastic-bodied tensioners may be nearing the end of their service life.
While driving on a smooth road, gently test the suspension. Listen for any 'thumping' or clunking from the front end, which can indicate that the upper wishbone bushings or shock mounts may need eventual attention.
Operate the convertible roof (if applicable) through its full cycle while the engine is running. Pay attention to any jerky movement or slow operation, which may suggest the hydraulic system fluid levels or seals require future maintenance.
Consider a full cooling system refresh, as the plastic coolant components often begin to show their age around this stage.
Ensure the supercharger drive belt and idler pulleys have been inspected or replaced to maintain optimal boost performance.
Monitor the condition of the rear suspension subframe bushings, as these endure significant torque from the supercharged V8 over time.
Check the coolant reservoir for any signs of debris or cloudiness, as clean coolant is vital for the health of your AJ-V8 engine.
Inspect the cabin floor carpets for any moisture, which helps identify if the heater core O-rings or door seals are staying tight.
Keep a log of the transmission fluid condition; while some were 'sealed for life', many owners find that a professional fluid and filter change helps extend longevity.
Regularly clean and treat the rubber door and window seals to ensure the cabin stays quiet and watertight during our New Zealand winters.
Monitor the engine oil level frequently between services, as these powerful V8s perform best when topped up with high-quality synthetic oil.
Estimated repair costs if issues arise
If the previous owner hasn't upgraded these to the later metal-bodied units, you might eventually need to budget for this proactive work to ensure engine peace of mind.
In cars of this age, it is common to consider replacing plastic cooling components like the thermostat housing and water pump to prevent unexpected overheating.
If the transmission starts showing signs of sluggishness or minor leaks, a professional service including the electrical sleeve and pan gasket can often resolve the issue.
