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. 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. Failure to follow these instructions may result in personal injury.

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 properly.

NOTE: About 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 by slowly turning the pressure relief cap one half turn counterclockwise. When the pressure is released, remove the pressure relief cap.





2. Place a suitable container below the radiator draincock. If equipped, disconnect the coolant return hose at the fluid cooler.
3. Open the radiator draincock. Remove the cylinder drain plug, if equipped, to drain the coolant from the cylinder block.





4. When the coolant is drained, make sure drain plugs are installed and tight.
1 Place a drain pan below the cylinder block.
2 Remove the drain plugs.








5. Close the radiator draincock when finished.
