Toyota 16400-0D230 Radiator Assembly

To remove the radiator, begin by disconnecting the negative battery cable and draining the engine coolant. Detach the upper and lower radiator hoses from the radiator, and disconnect the reservoir hose from the radiator filler neck. Remove the Cooling Fan Assembly, and if the vehicle has an automatic transaxle, disconnect the cooler lines from the radiator while using a drip pan to catch any fluid. Remove the two upper radiator mounting brackets, and carefully lift out the radiator, taking caution with dripping fluids and sharp fins. You can inspect the radiator for leaks, damage, and internal blockage, and if repairs are needed, it's recommended to seek assistance from a professional radiator shop or dealer service department due to the specialized techniques involved. Clean bugs and dirt from the radiator using compressed air and a soft brush, being careful not to bend the cooling fins. For installation, follow the reverse order of the removal procedure. Ensure that the rubber mounts are in place on the bottom of the radiator. After installation, fill the cooling system with the appropriate 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 necessary. On models equipped with an automatic transmission, check and add fluid as needed.

Before removing the radiator, the battery cable should be disconnected and the engine coolant should be drained.
