Engine Coolant Replacement
WARNING: This page is about a different variant/trim than selected.
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.
- Drain the water from the radiator, heater core and engine after unplugging the radiator drain plug and removing the radiator cap.
- Drain the water in the water jacket by unplugging the drain plug of the cylinder block.
- Remove the reserve tank and drain the coolant.
- Drain the cooling water then clean the path of the cooling water by injecting water into the radiator from the radiator cap area.
- Apply the designated sealant to the screw area of the cylinder block drain plug, and then tighten to the standard torque.
Specified sealant: 3M™ Nut Locking Part number 4171 or equivalent
Tightening torque: 44 +/- 5 N.m (33 +/- 3 ft-lb).
- Securely tighten the drain plug of the radiator.
- Assemble the reserve tank.
CAUTION: Do not use alcohol or methanol anti-freeze or any engine coolants mixed with alcohol or methanol anti-freeze. The use of an improper anti-freeze can cause corrosion of the aluminum components.
- By referring to the section on coolant, select an appropriate concentration for safe operating temperature within the range of 30 to 60 %. Use special tool MB991871 to refill the coolant. A convenient mixture is a 50 % water and 50 % antifreeze solution [freezing point: -31°C (-32.8°F)].
Recommended antifreeze: MITSUBISHI GENUINE Part number MD970389 or equivalent
Quantity: 5.0 dm 3 (5.3 quarts)
NOTE: For how to use special tool MB991871, refer to its manufacturer's instructions. - Reinstall the radiator cap.
- Start the engine and let it warm up until the thermostat opens.
- After repeatedly revving the engine up to 3,000 r/min several times, then stop the engine.
- Remove the radiator cap after the engine has become cold, and pour in coolant up to the brim. Reinstall the cap.
