Radiator Cap – Mopar (52028974AA)

The Mopar Radiator Cap (52028974AA) is a Genuine OEM cooling system component designed to maintain proper pressure within the vehicle’s radiator and cooling system. By regulating system pressure, the radiator cap helps raise the boiling point of the coolant, allowing the cooling system to operate more efficiently and preventing coolant loss during normal engine operation. Manufactured according to Mopar’s strict factory engineering standards, this radiator cap ensures dependable sealing and consistent pressure regulation.

Constructed with a durable metal cap assembly and high-temperature rubber sealing gasket, the radiator cap is engineered to withstand the heat, pressure fluctuations, and vibration present within the engine cooling system. The internal spring-loaded pressure valve is precisely calibrated to maintain the correct pressure level while allowing excess pressure to safely vent to the coolant recovery system when necessary. This controlled pressure management supports stable cooling system performance.

The 52028974AA radiator cap is engineered as a vehicle-specific direct-fit component, matching the original pressure rating, sealing diameter, and locking design used in Mopar factory cooling systems. Maintaining OEM specifications is essential for ensuring proper system pressure and reliable coolant circulation. Aftermarket radiator caps that do not meet factory tolerances may cause coolant leaks, overheating, or improper pressure regulation.

For professional technicians, installing a Genuine Mopar radiator cap ensures that cooling system service procedures maintain manufacturer pressure control standards and system reliability. For experienced DIY vehicle owners, selecting the OEM cap simplifies installation by matching factory radiator neck specifications and locking mechanisms without requiring adjustments.

A properly functioning radiator cap helps maintain stable cooling system pressure, supports efficient heat dissipation, and prevents coolant loss during operation. Replacing a worn or damaged cap helps restore correct system pressure and ensures reliable cooling system performance.

• Genuine Mopar OEM radiator cap
