5.7L V8 Hemi (EZH)
Petrol
Drive at 50-80 km/h under light throttle to allow the Multi-Displacement System (MDS) to activate, listening for a deep drone or feeling for any shuddering or hesitation.
Find an uneven gravel road or carpark with speed bumps, drive slowly, and feel for any knocking, loose play, or memory steer in the steering wheel.
Inspect the headliner near the rear window, feel the carpets in the rear passenger footwells, and check inside the under-seat storage bins for dampness or a musty smell.
Perform a cold start with the hood open and listen closely near the front wheel arches for a distinct metallic ticking sound that fades after a few minutes.
Perform a comprehensive engine oil and filter change using high-quality 5W-20 MS-6395 spec oil to preserve the MDS lifters. Rotate the heavy-duty tyres and inspect front brake pads and rotors for premature wear given the vehicle's weight.
Replace all 16 spark plugs (two per cylinder) to prevent misfires that stress the MDS. Flush and replace fluids in both front and rear differentials, service the transfer case, and inspect the RHD steering conversion components for wear.
Conduct a full transmission fluid and filter service on the ZF 8HP70 8-speed automatic. Replace the engine coolant, PCV valve, and serpentine drive belt. Inspect the water pump for leaks, a known weak spot around this mileage.
Strictly use high-quality 5W-20 engine oil meeting FCA MS-6395 specification to ensure proper operation of the MDS lifters.
Check the condition of the rear third brake light seal annually and reseal with silicone or an aftermarket gasket if degradation is visible.
Regularly lubricate and inspect all steering conversion grease points installed during the RHD conversion process.
Monitor coolant levels closely; look for dried pink crust around the water pump weep hole and thermostat housing.
Blow out sunroof drain tubes and clear debris from the cowl area to prevent water ingress into the cabin and electrical systems.
Estimated repair costs if issues arise
Required if a persistent 'Hemi Tick' is ignored and the lifter roller damages the camshaft lobe. This is a highly labour-intensive engine teardown.
Involves removing the manifolds, drilling out broken studs from the aluminum heads, and installing upgraded gaskets with stronger aftermarket studs or headers.
The ZF 8HP70 requires a specific fluid and a replacement plastic pan which houses an integrated filter. Critical for long-term towing reliability.
