Cooling System Draining, Filling and Bleeding
Draining
WARNING: Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions
can result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when
removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while
the pressure is released from the cooling system. When you are sure all the pressure has been released, (still with a cloth) turn and remove the pressure
relief cap.
CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated it must be recycled or disposed of
correctly.
CAUTION: Care must be taken to ensure the accessory drive belt does not become contaminated with engine coolant.
1. Release the pressure in the cooling system by slowly turning the pressure relief cap one half turn counterclockwise. When the pressure is released, remove the
pressure relief cap.
2. NOTE: Approximately four liters will drain from the radiator.
Place a suitable container below the radiator draincock. If equipped, disconnect the coolant return hose at the oil cooler.
Close the radiator draincock when finished.
Filling and Bleeding With RADKITPLUS
1. Using the special tool, install the RADKITPLUS and follow the RADKITPLUS manufacturer's instructions to fill and bleed the cooling system.
Filling and Bleeding Without RADKITPLUS
On 3.9L engines

On all engines
3. Open the heater air bleed.
4. Add coolant to the degas bottle allowing the system to equalize until no more coolant can be added.
On 3.0L engines
5. Close the engine air bleed when coolant begins to escape.
On all engines
6. Replace the degas bottle cap.
On 3.9L engines
CAUTION: Care must be taken to ensure the accessory drive belt does not become contaminated with engine coolant.
7. Add as much coolant as possible to the engine fill. The heater air bleed will remain open.
8. Replace the engine fill cap.
On all engines
9.
NOTE:
The heater air bleed remains open.

Start the engine and turn the heater to MAX position.
10. Close the heater air bleed when a steady stream of coolant comes from it, during engine idle.
11. Allow the engine to idle for five minutes, add coolant to the degas bottle as needed to maintain the cold fill MAX mark.
12. Reopen the heater air bleed to release any entrapped air and close again.
On 3.9L engines
13. Maintain engine speed of 2,000 rpm for 3-5 minutes or until hot air comes from the heater.
14. Return to idle and verify hot air is still coming from the heater.
On 3.0L engines
15. Maintain engine speed of 1,500 rpm for 3-5 minutes or until hot air comes from the heater.
16. Return to idle and verify hot air is still coming from the heater.
On all engines
17. Set the heater temperature setting to 24°C (75°F) and allow the vehicle to idle for two minutes.
18. Shut the engine off and allow to cool.
19. After the engine has cooled, add coolant to the degas bottle to bring the level to the cold fill MAX mark.
