Toyota 16400-66040 Radiator Assembly

Disconnect the negative battery cable. Drain the coolant into a container. Remove both the upper and lower radiator hoses. Disconnect the reservoir hose from the radiator filler neck. Remove the cooling fan. If equipped with an automatic transmission, disconnect the cooler lines from the radiator. Remove the grille center support. Remove the two upper radiator mounting brackets. Remove all the bolts that retain the radiator to the grille frame. Lift out the radiator. With the radiator removed, it can be inspected for leaks, damage, and internal blockage. Bugs and dirt can be cleaned from the radiator with compressed air and a soft brush. Installation is the reverse of the removal procedure. Be sure the rubber mounts are in place on the bottom 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 both radiator hoses becoming hot. Recheck the coolant level and add more if required. On automatic transmission equipped models, check and add fluid as needed. On most models, the coolant reservoir simply pulls up and out of the bracket next to the battery. Pour the coolant into a container. Wash out and inspect the reservoir for cracks and chafing. Replace it if damaged. Installation is the reverse of removal.
