6.2L (Supercharged Hemi V8) - SRT Hellcat
Petrol
Test drive task: Perform a low-speed, full-lock turn in a parking lot. | Description: Listen for any clunking or clicking from the front end, as these heavy machines can put significant stress on suspension bushings and ball joints over time.
Test drive task: Gently accelerate to highway speeds while observing the dash. | Description: Watch for any signs of hesitation or erratic power delivery; given the forced induction, ensuring the fuel delivery system is clean and consistent is helpful for long-term health.
Check this by: Cycling through all performance pages and Uconnect features while parked. | Description: Electronic gremlins can occasionally appear in infotainment systems of this generation, so confirming everything is responsive ensures you aren't chasing intermittent software glitches later.
Check this by: Inspecting the heat exchangers and front radiator intakes. | Description: Check for debris or bent fins, as keeping the supercharger cooling system unobstructed is essential for the engine to maintain its optimal performance characteristics.
Consider a full fluid flush, including the heavy-duty transmission fluid and differential oil to maintain performance shift quality.
Common to inspect the supercharger belt and tensioner assembly for signs of wear.
A good time to review the condition of the shock absorbers and suspension links to keep that iconic handling feel sharp.
Prioritize high-quality, full-synthetic oil changes every 8,000 to 10,000 kilometres to protect the internal components of the Supercharged Hemi.
Keep a close eye on brake pad and rotor thickness, as the Hellcat is a heavy vehicle that relies heavily on its high-performance Brembo setup.
Periodically check the coolant levels specifically for the supercharger intercooler circuit to ensure consistent intake temperatures.
Maintain the health of your battery, as these vehicles have sophisticated electronics that prefer a strong, consistent charge.
Regularly inspect tyre tread depth and alignment, as the torque delivery of this engine can make short work of rear tyres if the geometry is slightly off.
Estimated repair costs if issues arise
These high-performance rotors and pads offer excellent stopping power but require specialized components. Depending on the car's history, you might eventually need to budget for a complete set replacement.
If the supercharger belt or tensioner shows signs of wear, it's wise to replace them before they cause an issue. If this component needs attention in the future, the estimated cost in NZ is for parts and labour.
Given the weight of the Hellcat, suspension components work hard. If the ride starts to feel less precise, you might eventually need to budget for a full bushing or strut replacement to restore that 'factory fresh' feel.
