Cooling System Draining, Filling and Bleeding










Draining

WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.

NOTICE: Always fill the cooling system with the same coolant that is present in the system. Do not mix coolant types. Failure to follow these instructions may result in cooling system or engine damage.

NOTICE: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated it must be disposed of correctly. Failure to follow these instructions may result in cooling system or engine damage.

NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.

1. Release the pressure in the cooling system in the following sequence.

1. Make sure the engine is cool.

2. Wrap a thick cloth around the coolant pressure relief cap on the degas bottle. Slowly turn the cap counterclockwise (left) until the pressure begins to release.

3. Step back while the pressure releases.

4. When you are sure all the pressure has been released, use the cloth to turn and remove the cap.

2. Place a suitable container below the radiator draincock.

3. Open the radiator draincock and drain the coolant into a suitable container.

4. Close the radiator draincock when finished.
