OEM GM Radiators

The radiator holds the water and coolant that your engine needs in order to run cool and efficiently. Without that water, you engine would overheat and seize up. The radiator typically sits in the front of the vehicle regardless of whether you have an Outlook, Corvette, or Rendezvous, and there is a fan that helps draw cool air over it when you are driving.

The radiator has a hose attached to it that sends the water to the engine, and the water pump is responsible for pumping that water along its way. You add your coolant to the radiator in order to mix it with the water in the tank. The amount of coolant you need depends on where you live as some places get a lot colder than other places.

A genuine OEM GM replacement radiator is designed to fit exactly in the grille of your vehicle, which means that the hoses will all fit, every bolt hole will line up as it should, the brackets will be the right length, and the cap will fit. Ill-fitting aftermarket radiators may keep your engine from getting the coolant it needs.

Chances are that you will never need to replace the radiator in your vehicle because these parts are sturdy and built to last. However, they are subject to extreme temperatures and the interior can become clogged with rust or other debris, so you may need to clean them periodically.
