3.2L (M104) - RX320 Luxury V6
Petrol
Observe the transmission shifting from Park to Drive. If there is a noticeable delay or a 'clunk', it is common in vehicles of this age to consider checking the transmission mounts and fluid condition for signs of wear.
Engage the 4WD system while on a loose surface. Listen for any binding or clicking noises, as the transfer case components can eventually show their age in high-mileage Rextons.
During your highway drive, feel for vibrations through the steering wheel at 90-100km/h. This may suggest that the suspension bushings or steering linkage could eventually benefit from a professional inspection.
Operate the climate control through all settings. Since this is an older luxury model, it is prudent to ensure the blend door actuators are functioning smoothly, as they can sometimes become sluggish with time.
Usually marks the point where cooling system hoses and the water pump may begin to show signs of hardening or fatigue.
A common window to look at refreshing the suspension dampers and verifying the timing chain tensioner health on the M104 engine.
Often the time to evaluate the condition of the fuel pump and any original vacuum lines that may have perished.
Ensure the transmission fluid has been changed periodically, as the Mercedes-derived gearbox appreciates fresh oil.
Keep an eye on the coolant levels and quality, as the M104 engine performs best with clean, high-quality antifreeze.
Regularly inspect the underside for any signs of surface rust, particularly near the chassis rails, which is standard practice for NZ-used vehicles.
Check that the spark plugs are replaced at recommended intervals to maintain that smooth V6 power delivery.
Verify that the battery is healthy, as these electronics-heavy models require consistent voltage to keep modules happy.
Estimated repair costs if issues arise
In older luxury vehicles, it is often wise to consider a proactive cooling system overhaul, including the radiator and water pump, to ensure engine longevity. Depending on the car's history, you might eventually need to budget for this work to avoid overheating risks.
If the ride quality begins to feel less composed, it is common to consider replacing the suspension bushings and control arms. If this component needs attention in the future, the estimated cost in NZ covers parts and professional labor.
To keep the gear changes crisp, a professional transmission flush and filter change is a great way to look after your investment. If this needs doing, it is a sensible bit of preventative maintenance.
