5.0L Supercharged V8 (AJ-V8 Gen III) - XKR-S High Performance
Petrol
Check the timing chain tensioners by listening for a cold-start rattle. | Description: While these 5.0L engines are much improved over the earlier 4.2L units, it is common in higher-mileage examples to monitor for any metallic clicking during the first few seconds of startup, which may indicate the tensioners are ready for a refresh.
Test the adaptive dynamics system by toggling 'Dynamic Mode'. | Description: Observe if the suspension firming is consistent across all four corners. If the car feels unsettled or a warning light illuminates on the dash, it is worth investigating the health of the electronic damper actuators.
Monitor the coolant expansion tank during and after your drive. | Description: These engines run quite hot; keep an eye on the temperature gauge and check for any signs of weeping around the cooling system hoses or the plastic housing of the coolant reservoir, which can become brittle over time.
Cycle the convertible top or inspect the boot lid struts. | Description: Ensure the roof mechanism operates smoothly without hesitation. If the trunk lid feels heavy or fails to stay fully open, the hydraulic rams or struts may eventually require a replacement.
Consider a full transmission fluid and filter service, as the ZF 6-speed gearbox benefits from fresh fluid to maintain its smooth shifting character.
This is a sensible time to perform a preventative check on the supercharger drive belt and the cooling system ancillaries, such as the water pump and thermostat housing.
Expect to inspect the suspension bushings and control arms, as the weight and performance of the XKR-S can lead to natural wear in the rubber components.
Keep a consistent log of oil changes using high-quality synthetic lubricants every 10,000km to protect the supercharger internals.
Regularly clean the intercooler radiators to ensure airflow remains optimal for intake temperature regulation.
Check tire pressure and alignment frequently, as the staggered setup on the XKR-S can lead to uneven wear if not monitored.
Treat the leather surfaces with a quality conditioner to keep the interior supple in our varying New Zealand climate.
Ensure the battery is kept on a trickle charger if the vehicle is not being used as a daily driver to prevent electronic gremlins.
Estimated repair costs if issues arise
If you notice a rattling sound at idle that disappears when the revs rise, the supercharger nose cone coupler may be wearing. It is a specialized job, but addressing it keeps the supercharger healthy.
The XKR-S uses sophisticated electronic dampers. Depending on the car's history, you might eventually need to budget for a replacement unit if one stops communicating with the ECU.
To avoid a breakdown, it is common to consider a preemptive refresh of the water pump and associated plastic coolant pipes once the vehicle reaches higher mileage, as these are known to potentially fail as they age.
