3.6L Alloytec V6 - Mid-range AWD trim
Petrol
While idling in 'Park' and then shifting into 'Drive' or 'Reverse', listen for a metallic rattling sound coming from the engine bay or underneath the vehicle. | Details: This can sometimes indicate timing chain stretch, which is worth having a specialist listen to on the Alloytec V6.
Accelerate steadily from a stop on a sealed road and feel for any shudder or hesitation in the driveline. | Details: As the CX6 is AWD, smooth power delivery is key; any persistent vibration might suggest wear in the center bearing or CV joints.
While navigating a slow-speed turn, check for any clunking or clicking noises from the front suspension. | Details: The Adventra is a heavy vehicle, and it is common for the front control arm bushings or sway bar links to show signs of age after many years on Kiwi roads.
Observe the temperature gauge during a 15-minute drive and check for any 'milky' residue under the oil filler cap. | Details: While some condensation is normal in winter, consistent temperature fluctuations or milky oil may suggest the cooling system requires a thorough inspection.
Usually the time to evaluate the condition of the suspension struts and the AWD system fluid levels.
A good point to verify if the radiator has been replaced, as plastic end tanks can become brittle over time.
Focus on the condition of the transmission oil and the health of the engine's ancillaries like the alternator and power steering pump.
Check the transmission fluid condition; fresh fluid often helps the 5-speed auto shift more smoothly.
Inspect the coolant reservoir for any signs of leaks or discoloration.
Ensure all four tyres are of a matching brand and size to keep the AWD system happy.
Test the electronic stability control by checking that no warning lights remain illuminated after start-up.
Review the service history for regular oil changes, which are vital for the longevity of the Alloytec engine.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a significant job that involves removing the engine or transmission. It is wise to budget for this if the engine develops a distinct rattle.
Depending on the car's history, you might eventually need to budget for servicing the transfer case and diffs to ensure the 4WD system continues to operate silently.
Radiators, water pumps, and hoses in cars of this age are reaching the end of their service life; keeping the cooling system in top shape prevents more expensive engine issues later.
