Overview

The ACDelco GM Original Equipment RC115 20 PSI Radiator Cap is a factory grade component designed to help keep your cooling system sealed and efficient. Built to GM OE specifications, this cap mirrors the reliability you expect from your GM vehicle s original factory component.

Key benefits for GM vehicles

  • Seals and maintains pressure in the cooling system for safe operation and predictable performance
  • Raises the boiling point of engine coolant to help sustain engine efficiency under heat and load
  • Designed to fit most GM models, expanding compatibility across vehicle lines
  • GM recommended replacement part that matches your GM vehicle s original factory component
  • Delivers the quality, reliability, and durability associated with GM OE

Real world use shows this cap replacing a worn or degraded cap during routine maintenance or a cooling system service. The cap s sturdy metal body and precise seal resist heat and vibration, providing a confident seal under the hood during daily driving and during more demanding trips.

With GM OE standards, you can expect a fit that threads smoothly and seats firmly when dialed in correctly. This makes it a practical choice for professional garages and DIY enthusiasts who value factory level parts for GM engines.

Usage notes

  • Ensure the engine is cool before replacement to avoid burns and coolant spray
  • Verify compatibility with your GM model on the product page

  • Maintains reliable seal through multiple heat cycles
  • Factory replacement part ensures compatibility with GM OE interfaces
