Cooling System: Service and Repair

BLEEDING COOLING SYSTEM

Checking Engine Coolant Level:

1. Check engine coolant level at reservoir tank. The coolant level should be between the COLD and LEVEL lines at normal temperature. (20°C, 68°F). If low, check for leaks and add coolant up to the upper (COLD) level line. If the coolant temperature is higher than normal temperature, the coolant level should be higher than the upper level line.

Checking Engine Coolant Quality:

2. Check engine coolant quality. There should not be any excessive deposits of rust or scales around the radiator cap or radiator fill hole, and the coolant should be free from oil. If excessively dirty, clean the coolant passages and replace the coolant.

WARNING: To avoid the danger of being burned, do not remove the cap while the engine and radiator are still hot. Scalding fluid and steam can be blown out under pressure.

Removing Filler Plug:

Drain Cock Locations:

3. When replacing the engine coolant:
a. Remove the radiator cap.
b. Remove the filler plug from the inlet housing.
c. Drain the coolant from the engine and radiator drain cocks.
d. Clean coolant passages.
e. Close the engine drain cocks and torque to 18 Nm (13 ft. lb.). Close the radiator drain cock.

Checking Water Valve Lever Position:

4. Following the procedure below, open the water valve of the heater:
a. Ignition Switch ON.
b. A/C Blower Motor ON.
c. Using A/C temperature control button, raise the temperature select to the highest reading.
d. Check that the lever of the water valve is in the position shown in the illustration.

Filling Coolant Through Water Inlet:

5. Slowly add coolant to the water inlet until it is full. Use a good brand of ethylene glycol base coolant, mixed according to the manufacturer's specifications. Do not use concentrations below 50% or above 70% ethylene glycol/water mixture.

Tightening Water Inlet Housing Plug:

6. Install a new gasket and tighten the plug of the water inlet housing, then torque the plug to 44 Nm (33 ft. lb).

Adding Coolant To Reservoir Tank:

7. Slowly add coolant to the reservoir tank.

NOTE: The coolant level in the reservoir tank will drop after a while. Keep adding coolant until the water level no longer drops.

8. While the engine is idling for at least 10 minutes, add coolant (approx 4 liters, 4.1 quarts) up to the reservoir tank inlet to just below the overflow pipe. Securely tighten the reservoir tank cap.
9. Stop the engine after racing it for 5 mintues at 2,000 to 3,000 RPM.
10. After the coolant drops, remove the reservoir cap and add coolant up to the reservoir tank inlet to just below the overflow pipe. Securely tighten reservoir tank cap.

Capacity: 10.6 liters (11.2 quarts).
