Radiator Hose: Service and Repair

REMOVAL PROCEDURE





1. Disconnect the negative battery cable.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.

2. Drain the coolant from the radiator to a level below the hose being removed.

CAUTION: As long as there is pressure in the cooling system, the temperature can be considerably higher than the boiling temperature of the solution in the radiator without causing the solution to boil. Removal of the pressure cap while the engine is hot and pressure is high will cause the solution to boil instantaneously -possibly with explosive force - spewing the solution over the engine, fenders and the person removing the cap.

3. Remove air cleaner assembly.
4. Remove the radiator inlet hose and the clamp from the radiator and the coolant outlet (upper hose).
5. Remove the radiator outlet hose and the clamp from the radiator and the coolant pump (lower hose).


INSTALLATION PROCEDURE





1. Connect the radiator outlet hose and the clamps to the radiator and the coolant pump (lower hose).
2. Connect the radiator inlet hose and the clamps to the radiator and coolant outlet (upper hose).
3. Install air cleaner assembly.
4. Fill the coolant to the proper level.
5. Connect the negative battery cable.
6. Start the engine. After the engine reaches normal operating temperature, check for coolant leaks. Refer to Cooling System Leak Testing (Cooling System Pressure Test).
