To remove the radiator, start by disconnecting the negative terminal of the battery and the electrical connector from the electric fan motor. Drain the cooling system and, if the coolant is still in good condition, save it for reuse. On V6 models, remove the coolant reservoir/windshield washer reservoir assembly. If the vehicle has a mechanical cooling fan, remove it. Loosen the hose clamps and detach the radiator hoses from the fittings on the radiator. If stuck, twist and pull the hoses carefully to avoid damage. If needed, replace the hoses with new ones. Remove the radiator support and, if present, the auxiliary automatic transmission cooler and power steering cooler. If equipped, detach the internal cooler lines from the rear of the radiator and plug the lines and fittings. Remove the radiator mounting bolts and lift out the radiator, taking care not to spill coolant or scratch the vehicle's paint. Note the location of rubber seals for proper reinstallation. To install the radiator, first inspect it for leaks and damage. Clean the front of the radiator from bugs and dirt without bending the cooling fins. Check the radiator mounts for deterioration and ensure they are free of debris. Reverse the removal procedure for installation. Fill the cooling system with the correct antifreeze and water mixture, then check for leaks and ensure the engine reaches normal operating temperature. For automatic transmission-equipped vehicles, check and add transmission fluid as needed.
