5.0L V8 Supercharged - Track-focused performance flagship
Petrol
Check this by inspecting the coolant crossover pipes under the supercharger; in cars of this age, these plastic components can become brittle, so look for any signs of pink residue or weeping coolant in the engine valley.
While driving at low speeds, listen for any suspension knocks; the XKR-S features a more aggressive setup, and it is common for control arm bushings to show signs of fatigue after years of use on our undulating NZ roads.
Check this by operating the convertible roof (if applicable) or the windows; ensure the seals are intact, as moisture ingress can occasionally affect the electronic modules located in the rear quarter areas.
While idling, listen for a light rattle from the supercharger snout; it is worth noting that the coupler can wear over time, and a quiet, smooth idle is exactly what you want to hear from a well-maintained 5.0L V8.
Consider a full transmission fluid and filter service to maintain the ZF 6-speed's smoothness.
Recommended interval to inspect the condition of the supercharger drive belt and tensioner assembly.
A sensible time to assess the overall health of the dynamic suspension dampers and primary cooling system components.
Keep up with the premium synthetic oil changes every 10,000km to look after the complex variable valve timing systems.
Ensure the brake fluid is flushed every two years to maintain that sharp, track-focused stopping power.
Keep the battery on a trickle charger if the car sits for long periods; these electrical architectures are sensitive to low voltage.
Regularly clear the sunroof and door drains to prevent any debris buildup that might interfere with interior comfort.
Stick to high-octane 98 fuel to ensure the engine management system operates as intended and protects the high-compression supercharged internals.
Estimated repair costs if issues arise
If this cooling system component needs attention in the future, it is a proactive measure that ensures engine longevity. The job involves removing the supercharger to access the plastic piping which can fatigue over time.
Depending on the car's driving history, you might eventually need to budget for the large performance rotors unique to the XKR-S, as they are a significant wear item when driven with enthusiasm.
Given our road conditions, it is common to consider a suspension refresh to restore that sharp factory handling; this typically involves replacing various control arm bushings and ball joints.
