GM Genuine Parts Radiators are designed, engineered, and tested to rigorous standards, and are backed by General Motors. Radiators are heat exchangers, typically located in the front of the vehicle where air can flow through the fins and dissipate heat. Modern radiators are made from aluminum and plastic, while older vehicles used copper and brass. These radiators are designed to be corrosion resistant with optimal heat transfer characteristics. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov

Features and Benefits:

  • GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors
  • GM regularly updates production and service part designs to integrate new materials and technologies
