On 1999 and later models a special tool is needed to remove the transmission cooler lines from the radiator. Disconnect the negative battery cable from the battery. Drain the cooling system. If the coolant is relatively new or in good condition, save it and reuse it. Loosen the hose clamps, then detach the radiator hoses from the fittings on the radiator. If they're stuck, grasp each hose near the end with a pair of Channelock pliers and twist it to break the seal, then pull it off - be careful not to distort the radiator fittings! If the hoses are old or deteriorated, cut them off and install new ones. On four-cylinder and V6 models, disconnect the reservoir hose from the radiator filler neck. On four-cylinder and V6 models, remove the screws that attach the radiator fan shroud to the radiator and slide the shroud toward the engine. On inline six-cylinder models equipped with auxiliary electric cooling fans, remove the electric fan. On all inline six-cylinder models, remove the mounting bolts for the mechanical fan shroud, lift the shroud up until it clears the slots in the bottom bracket of the radiator, then push the shroud over the fan. If the vehicle is equipped with an automatic transmission, disconnect the cooler lines from the rear of the radiator. Use a drip pan to catch spilled fluid. Plug the lines and fittings. Remove the radiator mounting bolts. Carefully lift out the radiator. Don't spill coolant on the vehicle or scratch the paint. With the radiator removed, it can be inspected for leaks and damage. If it needs repair, have a radiator shop or dealer service department perform the work as special techniques are required. Bugs and dirt can be removed from the front of the radiator with compressed air and a soft brush. Don't bend the cooling fins as this is done. Check the radiator mounts for deterioration and make sure there's nothing in them when the radiator is installed. Installation is the reverse of the removal procedure. After installation, fill the cooling system with the proper mixture of antifreeze and water. Start the engine and check for leaks. Allow the engine to reach normal operating temperature, indicated by the upper radiator hose becoming hot. Recheck the coolant level and add more if required. If you're working on an automatic transmission equipped vehicle, check and add fluid as needed.
