3.6L Pentastar V6 - SXT/R/T Performance Trim
Petrol
Listen closely for any ticking or clicking sounds from the engine bay while at idle; in the 3.6L Pentastar, it is common to consider checking for premature camshaft or rocker arm wear.
Cycle through every gear position while stationary, then accelerate gently; if you notice hesitant or 'clunky' shifting, it is worth looking into the history of the 6-speed automatic transmission's fluid condition.
Test the electronic stability control and power steering responsiveness at low speeds; sometimes, sensors in the steering column or suspension geometry can show their age through warning lights.
Check the climate control output on both sides of the cabin; if one side blows colder than the other, it is a common indicator that the blend door actuators might eventually require attention.
Usually the time to inspect the cooling system, as the water pump and thermostat housings can start to show signs of age in these V6 units.
A common interval to check suspension bushings and struts, as New Zealand roads can be quite unforgiving on these larger sedans.
Often the point where spark plugs, ignition coils, and potential minor oil cooler leaks are addressed to keep the Pentastar engine running smoothly.
Keep a close eye on your engine oil levels; the Pentastar is a lovely performer, but regular, high-quality synthetic oil changes are key to its longevity.
Inspect the coolant reservoir regularly for any signs of discolouration or oil contamination.
Listen for any squeaks from the serpentine belt or tensioner pulleys during your regular Sunday morning checks.
Verify that the transmission fluid has been serviced according to the recommended schedule if you intend to keep the car for the long haul.
Check your tyre tread and pressure frequently, as this sedan benefits significantly from quality rubber to handle our winding Kiwi roads.
Estimated repair costs if issues arise
These units can eventually develop a weep over time due to the plastic housing material. It is a common job, but it involves some labor to access the 'V' of the engine.
Depending on the car's history and the roads it has traveled, you might eventually need to budget for refreshing the suspension joints to maintain that smooth handling feel.
If this component needs attention in the future, it is often wise to replace the water pump and thermostat as a preventative measure to keep things running cool.
