5.7L (Hemi V8) - Limited/Overland
Petrol
While parked on an incline, shift from Park to Reverse and Drive to listen for any clunking sounds from the drivetrain, as the XK is known to develop wear in the differential bushings over time.
Check the climate control by cycling through all fan speeds and temperature zones; these models often experience issues with the HVAC blend door actuators which can be labour-intensive to access.
Observe the dashboard for any flickering lights or 'Service 4WD' messages, as the electronic control modules in these vehicles can be sensitive to voltage fluctuations if the battery is aging.
During your test drive, find a stretch of smooth road and listen for a slight 'thumping' from the suspension, as the upper control arm bushings and ball joints are common wear items on this heavy chassis.
Consider a full transmission fluid and filter service to ensure the heavy-duty automatic gearbox continues to shift smoothly.
This is an ideal time to assess the cooling system, specifically the radiator hoses and water pump, to ensure the Hemi engine maintains optimal operating temperatures.
The suspension components, including struts and bushings, likely deserve a professional inspection to maintain the ride quality expected of a large SUV.
Prioritise regular synthetic oil changes every 10,000km to keep the Hemi's cylinder deactivation system functioning reliably.
Keep an eye on the spark plugs; with 16 plugs in the 5.7L Hemi, replacing them is a more significant task but vital for engine efficiency.
Ensure the transfer case fluid is refreshed periodically if you plan on doing any light towing or off-road driving.
Inspect the steering rack for any minor fluid seepage, which is a common observation for vehicles of this generation.
Check the condition of the brake rotors and pads regularly, as the Commander is a heavy vehicle that puts significant demand on the braking system.
Estimated repair costs if issues arise
Because the XK is a heavy machine, these parts work hard. Depending on the car's history, you might eventually need to budget for a suspension refresh to restore that 'solid' feel on the road.
If this component needs attention in the future, the estimated cost in NZ is higher than expected because the dashboard often requires partial removal to reach the internal mechanisms.
In cars of this age, it's common to consider preventative maintenance on the cooling system, including a new water pump and radiator to avoid potential overheating issues down the track.
