3.6L Pentastar V6
Petrol
While the vehicle is parked after a warm run, check the 'V' of the engine valley under the intake manifold for any signs of oil pooling or coolant residue, as the plastic oil filter housing can sometimes develop leaks in vehicles of this age.
During a cold start, listen closely to the upper engine area for a rhythmic ticking sound; in some Pentastar engines, this may suggest that valvetrain components like rockers or lifters could benefit from an inspection or future replacement.
While accelerating and decelerating through lower gears, pay attention to the smoothness of the 8-speed transmission; if you notice any hunting or firm shifts, it may be worth budgeting for a fluid and filter service to maintain its longevity.
Check this by cycling through the heater and air conditioning modes; if you hear a clicking sound behind the dashboard, it is common to consider that a blend door actuator might eventually need to be replaced.
This is a great time to consider replacing the spark plugs and performing a comprehensive cooling system flush to keep the Pentastar V6 running efficiently.
At this stage, many owners choose to service the transmission (pan and fluid) and inspect the accessory drive belt and tensioners for signs of wear.
In higher mileage examples, it's wise to evaluate the suspension bushings and shock absorbers to ensure the truck maintains its original ride quality and handling safety.
Ensure the use of MS-6395 specification synthetic oil during every service to protect the variable valve timing system.
Regularly inspect the plastic coolant Y-pipes and connectors for any signs of brittleness or weeping.
Check the cabin air filter and the seal around the high-mount third brake light to prevent moisture from entering the interior.
Monitor the battery health, as the complex electronics in the 4th Gen Ram are sensitive to voltage fluctuations.
Rotate the tyres every 10,000km to manage the wear patterns caused by the vehicle's weight and RWD/4WD dynamics.
Estimated repair costs if issues arise
Depending on the car's history, you might eventually need to budget for an upgraded aluminium housing if the original plastic unit begins to weep oil. This job involves removing the upper and lower intake manifolds.
In cars of this age, it's common to consider a proactive refresh of the rocker arms if a 'tick' develops. Addressing this early prevents potential wear on the camshafts.
If this component needs attention in the future, the estimated cost in NZ covers the specialized ZF-compliant fluid and the replacement of the integrated pan/filter unit.
While more common on the V8, the V6 can occasionally experience broken manifold studs. Future budget planning for high-grade replacement bolts and gaskets is a sound strategy.
