Radiator Hose Replacement Upper

1. Have a suitable container ready to catch the draining coolant.
2. Drain the coolant from the radiator until the fluid level is below the upper radiator inlet. Close the drain cock when draining is complete.
3. Remove the outer clamps and the upper radiator hose assembly from the radiator and the engine.
4. Remove the clamps and the rubber radiator hoses from the upper pipe section.



5. Inspect the upper pipe section for evidence of corrosion.
6. Clean the upper pipe section in order to remove any corrosion present.

1. Install the rubber radiator hoses and the upper pipe section with the clamps. Do not tighten the clamps.
2. Install the upper radiator hose assembly to the engine and the radiator.

Tighten
Tighten the hose clamps to 4 N·m (35 lb in).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Fill the radiator with the recommended coolant. Refer to Recommended Fluids and Lubricants in General Information.

Radiator Hose Replacement Lower

1. Have a suitable container ready to catch the draining fluid.
2. Drain the coolant from the radiator. Close the drain cock when draining is complete.
3. Loosen the clamp. Disconnect the overflow hose from the lower hose assembly.
4. Remove the nuts, the U-bolt, the cradle, and the lower hose assembly from the bracket.



5. Remove the outer clamps and the lower hose assembly from the coolant pump and the radiator.
6. Remove the clamps and the rubber hose sections from the lower pipe section.



7. Inspect the lower pipe section for evidence of corrosion.
8. Clean the lower pipe section in order to remove any corrosion present.

1. Install the rubber hose sections and the lower pipe section with the clamps.
2. Install the lower radiator hose assembly to the radiator and the coolant pump with the clamps.

Tighten
Tighten the clamps to 4 N·m (35 lb in).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.




3. Install the lower radiator hose assembly to the bracket with the U-bolt, the cradle and the nuts.

Tighten
Tighten the nuts to 38 N·m (28 lb ft).

4. Connect the overflow hose to the lower hose assembly with the clamp.
5. Fill the radiator with the recommended coolant. Refer to Recommended Fluids and Lubricants in General Information.
