OEM GM Radiators

What Radiators Do?

You may be familiar with your car's radiator but may not know how important it is. Your radiator is a part of your vehicle's cooling system and helps the engine from getting too hot. Your car pumps coolant through the engine, then carries it away from the engine block. The coolant takes heat from the engine and moves it to your radiator. Then, the radiator blows air across the liquid, causing it to cool down.

Signs of Radiator Problems

Like other parts of your GM model, your radiator can fail. It is recommended to look out for the following symptoms, which include:

  • Strange or unfamiliar engine noises
  • Ethylene glycol odor
  • Dirty antifreeze
  • An antifreeze leak
  • Car heating and AC malfunctions
  • A high reading temperature gauge

To get a better understanding of these causes, be sure to run a thorough vehicle inspection.
