    Good Maintenance Practices - Section 1 - Bullet 1Replace coolant with a mixture of antifreeze and water according to the owner's manual recommendations.
    Faq - Answer 1No, 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.

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. &#9888;<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov
