Draining

WARNING: Never remove the radiator 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 radiator cap when removing the radiator cap, wait until the engine has cooled, then wrap a thick cloth around the radiator 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 radiator 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 properly.

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





1. Release the pressure in the cooling system by slowly turning the radiator cap one half to one turn counterclockwise to the first stop on the filler neck. When the pressure has been released remove the radiator cap.
2. Place a suitable container below the radiator draincock. If equipped disconnect the coolant return hose at the oil cooler.





3. Open the radiator draincock. If equipped, remove the cylinder drain plug to drain the coolant from the cylinder block.





4. When the coolant is drained, make sure drain plugs are installed and tightened.





5. Close the radiator draincock when finished.
