4.7L PowerTech V8
Petrol
Perform a cold start after the vehicle has sat overnight and listen closely to the wheel wells for a distinct ticking sound that fades as the engine warms up.
Remove the oil filler cap to inspect for milky residue or thick black sludge, and listen for heavy top-end tapping/clatter at hot idle.
Accelerate from a standstill through all gears, then perform a kick-down acceleration at highway speeds, checking for delayed engagement or shuddering.
For converted Right-Hand Drive models, inspect the steering transfer box, custom linkages, and dashboard wiring looms for wear or rubbing.
Replace all spark plugs (this engine is sensitive to plug wear), replace the PCV valve to manage crankcase pressure, and proactively replace the water pump and thermostat.
Flush and renew the cooling system with correct HOAT coolant to prevent overheating. Perform a transmission service including replacing both the sump and spin-on filters.
Perform a comprehensive lube, oil, and filter service. Inspect front suspension boots, grease steering linkages, and check differential fluid levels.
Focus on high-mileage maintenance including differential fluid changes, checking the condition of the driveshaft U-joints and front wheel bearings.
Adhere to a strict 5,000 km to 7,500 km engine oil change interval using high-quality 5W-30 oil to prevent sludge build-up.
Inspect the plastic radiator side tanks and coolant hoses regularly for hairline cracks or weeping, as this engine does not tolerate overheating.
Ensure only Chrysler-approved ATF+4 fluid is used in the transmission; using generic fluids will cause shift issues and clutch wear.
Grease the front suspension and steering ball joints at every oil service if aftermarket greaseable joints have been installed.
Inspect the rear 'dash' area near the window for signs of water ingress, often caused by a weathered third brake light seal.
Estimated repair costs if issues arise
Requires extracting broken studs from the aluminum cylinder heads. Often requires removing inner fender liners for access.
Replacement of the internal solenoid block, dual filters, pan gasket, and fresh ATF+4 fluid to cure shifting issues.
If the 4.7L overheats, the aluminum heads warp easily. Requires head removal, machining, new gaskets, and head bolts.
Replacing worn factory front upper/lower ball joints and outer tie rods with high-quality aftermarket greasable units.
