Coolant: Service and Repair
ENGINE COOLANT REPLACEMENT
Check the cooling system parts such as the radiator, heater and oil cooler hoses, thermostat and their connections for leakage and damage.
1. Set the temperature control knob to the "HOT" position.
2. Run the engine until the engine coolant warms, and then stop the engine.
WARNING: When removing the radiator cap, use care to avoid contact with hot coolant or steam. Place a shop towel over the cap and turn
the cap counterclockwise a little to let the pressure escape through the vinyl tube. After relieving the steam pressure, remove the cap by
slowly turning it counterclockwise.
3. Drain the water from the radiator, heater core and engine after unplugging the radiator drain plug and removing the radiator cap.
4. Drain the water in the water jacket by unplugging the drain plug of the cylinder block. For the right bank side on AWD vehicles, drain the engine
coolant from the water feed tube assembly of the transfer box.
5. Remove the radiator condenser tank assembly and drain the coolant.
6. Drain the coolant then clean the path of the coolant by injecting water into the radiator from the radiator cap area.
7. Apply the designated sealant to the screw area of the cylinder block drain plug, and then tighten to the standard torque.
Specified sealant: 3M AAD Part No.8731 or equivalent
Tightening torque: 39 ± 5 Nm (29 ± 3 ft. lbs.)
