To remove the radiator, begin by draining the cooling system. Remove the engine cooling fan assembly and disconnect the radiator and coolant reservoir overflow hoses. Detach the air guides from the sides of the radiator and remove the air filter housing air inlet duct. Disconnect the transaxle fluid cooler lines from the radiator and, if necessary, remove the air filter housing for additional clearance. Pinch the fastening tabs at the top of the condenser to disconnect it from the radiator, then carefully lift the condenser and separate it from the radiator and remove the radiator.

After installing the new radiator, the cooling system should be filled with the appropriate mixture of antifreeze and water. Then, the engine should be started and checked for leaks. The coolant level should be rechecked after the engine reaches normal operating temperature. Additionally, the transaxle fluid should be checked and more should be added if necessary.
