OEM GM Radiators

Refine Results

The factory radiator that came in your GM vehicle is essential when it comes to keeping your engine running right. The engine creates quite a lot of heat when it's in use. Without cooling, it will quickly overheat and possibly shut down. Your radiator prevents that by keeping the various engine parts cool.

How Radiators Work

Fluid, usually a mixture of coolant and water, is sent from the radiator to the engine block. There it collects the heat that has built up. The fluid then makes its way back to the radiator through a series of hoses. The radiator's large, flat, finned surface allows the collected heat to dissipate into the atmosphere. The coolant mix then is free to return to cool the engine again.

Signs of Radiator Trouble

Don't risk a failing radiator causing even more damage. Indicators include:

  • The "Low Coolant" dash light comes on
  • You see pools of red, green, or yellow liquid under your car, SUV, or truck
  • You hear odd engine noises
  • You smell the sweet odor of coolant
  • You have trouble maintaining a consistent cabin temperature

If your radiator is at fault, replace it as soon as you can. Make sure to use genuine GM parts, however, as they're the only ones guaranteed to fit your model. Our online auto parts department is ready to ship your order directly to your door, so buy today and save!
