Disconnect the negative battery cable from the battery. Raise the front of the vehicle and support it securely on jackstands. Remove the lower splash pans. Drain the cooling system. If the coolant is relatively new or in good condition, save it and reuse it. On 5S-FE models disconnect the coolant temperature switch connector from the radiator. Disconnect the coolant reservoir hose from the radiator and loosen the upper and lower hose clamps, then detach the radiator hoses from the fittings. Remove the engine relay box and on vehicles with ABS disconnect the ABS relay box from the radiator. Remove the upper radiator cowl. Disconnect the cooling fan connector. If the vehicle is equipped with an automatic transaxle, disconnect the cooler lines and plug the lines and fittings. Remove the radiator mounting bolts. Carefully lift out the radiator. Remove the bolts securing the cooling fan to the radiator and pull it free. 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 radiator with a garden hose or a soft brush. Installation is the reverse of the removal procedure. Be sure the rubber cushions are seated properly at the base of the radiator. 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 transaxle equipped vehicle, check and add fluid as needed.
