Draining

WARNING: Do not remove the radiator cap while the cooling system is hot Serious personal injury may result. Only remove the radiator cap from a cool engine.

ENGINE COOLANT RECYCLING
The use of a waterless, approved coolant recycling system on the vehicle eliminates the need for evacuation. This method removes the used coolant and replaces it with approved new or with recycled coolant. When this equipment is not available use the following procedure.

PROCEDURE
1. Make sure the system has cooled, then remove the radiator filler cap.
2. Place a drain pan under the radiator drain cock.





3. Install a tube on the drain cock.





4. Place the end of the tube in the drain pan.
5. Open the drain cock completely.
6. Allow the cooling system to drain until the flow stops. If only the radiator is drained, up to 40% of the old coolant will remain in the system.
7. Place a drain pan under the engine.





8. Remove the drain plug from the side of the engine block.
9. Apply a sealer to the threads and then tighten the engine block drain plug(s).
^ Tighten the engine block drain plugs to 32 Nm (25 ft. lbs.).

NOTE: Dispose of the used engine coolant properly. Store it in a used coolant Holding Tank awaiting proper disposal or recycling. Never pour used coolant down the drain. Ethylene glycol antifreeze is a very toxic chemical. Disposal into the sewer system or into the ground water is both environmentally irresponsible and illegal.

10. If the drained coolant is discolored, flush the cooling system.
11. If the drained coolant appears normal, continue with the filling procedure.
