Engine Coolant (Change)
Check the cooling system parts such as the radiator, heater and oil cooler hoses, thermostat and their connections for leakage and damage.
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.
- Remove the radiator cap and drain plug to drain the coolant.
- Remove the water feed hose B, and drain the coolant in the water jacket.
- Remove the radiator condenser tank assembly and drain the coolant.
- Drain the coolant then clean the path of the coolant by injecting water into the radiator from the radiator cap area.
- Install the water feed hose B.
- Securely tighten the radiator drain plug.
- Assemble the radiator condenser tank assembly.

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.
- Vehicles for California emission regulation: If the coolant contact the PremAir® direct ozone reduction (DOR) radiator, wash it with water at once.
- 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 (-24 °F)].
Recommended antifreeze: Long Life Antifreeze Coolant or an equivalent
Quantity: 9.5 dm 3 (10.0 quarts)
10.0 dm 3 (10.6 quarts) <Vehicles with Towing Package or DOR radiator>
- 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, stop the engine.
- Remove the radiator cap after the engine has cooled, and pour in coolant up to the brim. Reinstall the cap.CAUTION: Do not overfill the radiator condenser tank assembly.
- Add coolant to the radiator condenser tank assembly between the "FULL" and "LOW" mark if necessary.
