Q: How do you remove the radiator on Pontiac Grand Prix?
A: To remove the radiator, start by disconnecting the negative battery cable. Drain the cooling system and remove the air cleaner assembly. If the vehicle has an automatic transaxle, disconnect the cooler lines from the radiator and cap the ends. Remove the engine cooling fan assembly. Loosen the hose clamps and detach the radiator hoses from the fittings. Disconnect the reservoir hose from the radiator neck. Plug the lines and fittings to prevent spillage. Remove the bolts from the radiator mounting panel and carefully lift out the radiator. Inspect it for leaks and damage. Clean the radiator with compressed air and a soft brush. Check the radiator mounts for deterioration. To install the radiator, start by installing the cooler line retaining clips onto the quick-connect fitting. Snap the cooler lines into place on the quick-connect fittings and reinstall the plastic collars. Fill the cooling system with the proper mixture of antifreeze and water, bleed the system of air, and check for leaks. If working on an automatic transaxle equipped vehicle, check and add fluid as needed.
