- Description: ACDelco GM Original Equipment Radiators are GM-recommended replacements for your vehicles original components. 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. These original equipment radiators have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. ⚠ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

| FAQ - Answer 1 | No, an overheating engine could mean an issue with your radiator, but there are other pieces of the cooling system that could cause the engine to overheat. It is important to check for coolant leaks or a malfunctioning fan. If you look at the radiator and there is a lot of corrosion or holes there may be a problem with the radiator. Either way it is important to get the whole cooling system checked when your engine overheats. |
