Petrol
While driving at low speeds, gently turn the steering wheel left and right. Listen for any knocking sounds from the front end, as worn lower control arm bushes are a common observation in vehicles of this age.
With the car in Park, gently shift through the gears. If the transmission feels hesitant or jerky when engaging 'Drive' or 'Reverse', it is a good idea to consider that the transmission fluid and filter may be due for a service.
During your highway portion of the test drive, monitor the temperature gauge closely. Ensure it stays steadily in the middle; fluctuations could be an indicator that the cooling system components may eventually require an inspection.
Check this by turning the climate control to both heat and cold while stationary. If the air doesn't switch temperatures correctly, the blend door actuator can sometimes become stuck, which is a common item to keep an eye on.
Consider a major service including spark plugs and transmission fluid flush.
Usually the time to inspect suspension struts and steering rack mounts for signs of wear.
Monitor the intake manifold gasket for any signs of seepage or coolant loss.
Keep a consistent eye on the coolant level in the overflow bottle to ensure the cooling system is happy.
Change the engine oil and filter every 10,000km to keep that Ecotec V6 running smoothly for the long haul.
Check the condition of the serpentine drive belt for any signs of cracking or fraying.
Ensure the power steering fluid is topped up and clean to keep steering effortless.
Regularly inspect the tyre pressures and tread wear to ensure safe handling on New Zealand roads.
Estimated repair costs if issues arise
In older Ecotec engines, these gaskets can occasionally deteriorate over time. If you notice a minor loss of coolant or oil seepage, you might eventually need to budget for a gasket replacement to keep the engine seals fresh.
To keep your gear shifts smooth, it's wise to consider a transmission fluid and filter change if the service history is unclear. This is a great preventative measure for the long-term health of the gearbox.
Given the age of these vehicles, the rubber bushes and shock absorbers may have naturally worn down. If you feel the ride becoming a bit 'loose,' it's common to plan for a suspension refresh to restore that classic Commodore comfort.
