• Description:

  The Guardian of Your Cooling System
  A radiator cap is far more than a simple lid; it is a precision-calibrated pressure relief valve that dictates the boiling point of your entire engine. The Genuine Mopar Radiator Cap (52014479AB) is engineered to maintain the exact cooling system pressure required for peak thermal efficiency. While aftermarket caps often use generic spring tensions that can lead to early boil-overs or blown hoses, this Mopar cap is built to the rigorous specifications of your vehicle’s original cooling architecture.

  • Precision Pressure Regulation: This cap features a high-grade calibrated spring designed to hold a consistent, factory-specified PSI. This raises the boiling point of your coolant, allowing your engine to operate safely in extreme heat or under heavy loads without the risk of cavitation or localized hotspots.
  • Dual-Seal Integrity: Engineered with premium EPDM rubber gaskets, this cap provides a superior airtight seal against the radiator neck. It prevents coolant loss through evaporation and ensures that the vacuum-draw system functions perfectly, pulling coolant back from the reservoir as the engine cools.
  • Fail-Safe Venting: In the event of a thermal spike, the integrated relief valve is designed to vent pressure at a precise threshold. This protects your water pump, heater core, and radiator seams from the catastrophic damage caused by over-pressurization.

  Why Choose Genuine Mopar?
  Choosing the Genuine Mopar Radiator Cap (52014479AB) eliminates the "close enough" mentality of universal cooling parts. Aftermarket caps often suffer from "seal swell" or spring fatigue, which can lead to mysterious coolant loss and engine-damaging temperature spikes.

  • The Latest Engineering Revision: This part number represents the most current factory-authorized design (Revision AB), replacing and improving upon the original 52014479AA to provide enhanced seal longevity and better resistance to modern long-life coolants.
  • Chemical-Resistant Metallurgy: The internal components are fabricated from corrosion-resistant stainless steel and brass, ensuring the relief valves won't seize or scale over years of submersion in hot coolant.
  • True Professional Reliability: Your engine’s longevity depends on a stable cooling system. Using the same cap the factory installed ensures that your cooling system pressures remain within the safe operating window intended by the manufacturer.
  • Factory-Backed Warranty: Every Mopar cooling component is supported by a manufacturer-backed warranty, offering a level of safety-testing and peace of mind that independent retailers simply cannot match.
