My engine is overheating does this mean I need to replace my radiator?

GM Genuine Parts Engine Radiator

About this product

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.

Limited Lifetime Warranty for Parts (plus Labor if installed by a GM dealer)

Maintain proper coolant levels and check levels regularly. Also make sure to check coolants concentration because the water ratio can affect the freezing or boiling point. (Note: Never attempt to remove a surge or radiator cap while the engine is hot. Serious injury could result.)

Replace coolant with a mixture of antifreeze and water according to the owner's manual recommendations.
Evaluate radiator and radiator cap for leaks, corrosion, or worn cap gasket. Make sure to pressure test the cap.
Have cooling system inspected immediately if instrument panel-mounted temperature gauge indicates engine overheating.
Periodically, remove bugs, leaves, and other debris from the front of the radiator. They can block airflow and substantially reduce cooling efficiency.

Frequently Asked Questions

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.
