Standard Procedure: Draining

WARNING:

Do not remove the cylinder block drain plugs or loosen the radiator draincock with system hot and under pressure. Serious burns from coolant can occur.

DO NOT remove radiator cap first. With engine cold, raise vehicle on a hoist and locate radiator draincock.
NOTE:
Radiator draincock is located in the radiator tank at the bottom.
Attach one end of a hose to the draincock. Put the other end into a clean container. Open draincock and drain coolant from radiator. This will empty the coolant reserve/overflow tank. The coolant does not have to be removed from the tank unless the system is being refilled with a fresh mixture. When tank is empty, remove radiator cap and continue draining cooling system.
