5.7L HEMI V8 (EZH) - R/T
Petrol
Listen for ticking at idle. | Description: While the car is stationary, listen closely for a persistent 'tick' from the engine bay. It is helpful to consider if this is a sign of HEMI manifold bolt fatigue or lifter wear, which is a known nuance in these engines.
Check the transmission shift quality. | Description: During moderate acceleration, feel for any hesitation or 'hunting' in the gears. In higher-mileage examples, the NAG1 transmission can benefit from a fluid service to ensure smooth power delivery.
Inspect the dashboard for 'bubbling' or trim separation. | Description: Check the top of the dashboard near the windshield for any lifting or air bubbles under the material, as common UV exposure in NZ can sometimes affect the adhesion of the interior plastics over time.
Test the suspension over varied surfaces. | Description: While driving, listen for clunks when going over speed bumps. It is worth keeping in mind that the front control arms and bushings are high-wear items on the heavier LD platform.
Consider a full cooling system refresh and spark plug replacement, as the 5.7L HEMI uses 16 plugs which are due around this interval.
It is often a wise time to inspect the water pump and serpentine belt tensioner for signs of aging to ensure reliable road trips.
Evaluate the condition of the drivetrain mounts and transmission fluid health to keep the ride feeling tight and responsive.
Keep a close watch on the engine oil level between changes, as these engines appreciate regular topping up.
Ensure the air filter is kept clean to allow the HEMI to breathe freely.
Regularly inspect the tire tread, as the torque from the 5.7L can lead to uneven wear if alignment isn't monitored.
Check the battery health periodically, as these electronics-heavy sedans can be sensitive to voltage drops.
Maintain a clear service record to document regular synthetic oil changes, which the MDS system heavily relies on.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of the labour required to access the manifold. It is common to budget for this if you hear a ticking sound upon cold start.
Depending on the car's history, you might eventually need to budget for a complete front-end suspension overhaul to keep the handling precise.
Because the 5.7L HEMI requires two spark plugs per cylinder, the service cost is higher than a standard four-cylinder vehicle, so plan for this every 100,000km.
