Mopar 5278767AB Radiator Cap: OEM Fit, Pressure Precision, and Peace of Mind
When your Mopar's cooling system needs a new cap, the 5278767AB is the exact factory-spec part designed for vehicles like the 2020 Dodge Charger SXT with the 3.6L engine. This cap maintains the correct system pressure, preventing overheating and coolant loss. Here's what to consider before you buy.
Key Considerations Before Buying
- Vehicle compatibility: Confirm your car's make, model, and engine size matches the 5278767AB application. The reviews highlight its use on a 2020 Dodge Charger SXT 3.6, but always double-check your owner's manual or use an online fitment guide.
- OEM vs. aftermarket: Genuine Mopar caps are engineered to exact tolerances, ensuring a proper seal and pressure release. Aftermarket caps may vary in quality, leading to leaks or premature failure.
- Inspect your old cap: If your current cap shows signs of rubber splitting or cracking (as noted in reviews), replace it promptly to avoid coolant loss and potential engine damage.
