Cooling System - Radiator

RADIATOR - COMPONENTS

REMOVAL

1. Disconnect the radiator cooling fan motor connector.

2. Set the temperature control switch to the maximum heat position.

3. Remove the radiator drain plug and drain the coolant.

4. Disconnect the upper and lower radiator hoses and the reservoir tank hose.

5. On models with automatic transaxle, disconnect the automatic transaxle oil cooler hoses.

After disconnecting the automatic transaxle oil cooler hoses, plug the hose openings, radiator fittings, and automatic transaxle connections to prevent transaxle fluid leakage and entry of foreign matter.

6. Remove the radiator support mounting bolts.

7. Remove the radiator together with the radiator cooling fan.

8. Remove the cooling fan from the radiator.

INSPECTION

1. Inspect the radiator for bent or damaged fins, and check that there are no foreign objects between the fins.

2. Inspect the radiator for damage, scale, rust, or signs of corrosion.

3. Inspect the radiator hoses for cracks, damage, or deterioration (wear).

4. Inspect the reservoir tank for damage.

5. Inspect the radiator cap spring for damage.

6. Check the radiator cap valve opening pressure using a special cooling system tester.

RADIATOR COOLING FAN MOTOR

1. Check that the radiator cooling fan rotates when battery voltage is applied to the motor terminals.

2. Check that the radiator cooling fan operates without abnormal noise.

INSTALLATION

1. Fill the radiator and reservoir tank with clean coolant.

2. Start the engine and warm it up until the thermostat valve opens. Then stop the engine.

3. Remove the radiator cap and add coolant up to the base of the radiator filler neck, then add coolant to the reservoir tank up to the upper mark.

4. Check that there are no coolant leaks from the radiator, hoses, or connections.
