WARNING
When you remove the radiator cap, be careful to avoid contact with hot coolant or steam. Put a shop towel over the cap and turn the cap counterclockwise just a small amount to allow the pressure to escape through the vinyl tube. After reducing the steam pressure, remove the cap by slowly turning it counterclockwise.
CAUTION
Do not use alcohol or methanol anti-freeze or any engine coolant mixed with alcohol or methanol anti-freeze. The use of non-recommended anti-freeze can cause aluminum components to corrode.
- Drain the coolant by removing the radiator cap and radiator drain plug (and the engine coolant drain plug, if equipped).
- Remove the reserve tank and drain the coolant.
- After completely draining the coolant, install the drain plugs and flush the engine and radiator using a radiator cleaning fluid.
- After the flushing is completed, completely drain the cleaning fluid and install the radiator and engine drain plugs.
- Select an appropriate concentration for safe operating temperature within the range of 30% to 60%. Use special tool #MB991871 or equivalent to refill the coolant. A good mixture is a 50% water and 50% antifreeze solution. The freezing point of this mixture is -32.8°F (-31°C). The manufacturer recommends using Long Life Antifreeze Coolant or an equivalent. The correct quantities are below:
- 2.4L Engine: 8.5 quarts (8.0 ml)
- 3.8L Engine: 8.7 quarts (9.2 ml)
- Install the radiator cap.
- Start the engine and let it warm up until the thermostat opens.
- Rev 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.
CAUTION
Do not overfill the reserve tank.
- Add coolant to the reserve tank between the "FULL" and "LOW" mark if necessary.
