WARNING: DO NOT REMOVE THE CYLINDER BLOCK DRAIN PLUGS OR LOOSEN THE RADIATOR DRAINCOCK WITH THE COOLING SYSTEM HOT AND UNDER PRESSURE. SERIOUS BURNS FROM COOLANT CAN OCCUR.

DO NOT remove the pressure cap first. With the engine cold, raise and support the vehicle on a hoist and locate the radiator draincock.
NOTE: Radiator draincock is located on the left/lower side of radiator facing to rear of vehicle.
Attach one end of a hose to the draincock (2). Put the other end into a clean container. Open draincock and drain the coolant from the radiator. This will also empty the coolant recovery reservoir (1). When the tank is empty, remove the pressure cap and continue draining the cooling system.
