COOLANT DRAINING

drain port (Figure 5) to catch drained coolant. The
collected coolant will be reused later. Make sure no
foreign particulates or contaminates are present in
the drained coolant.
2. Using an open-ended wrench, remove the coolant drain
plug and drain approximately 1/2-3/4 gallons of coolant
(Figure 5) from the coolant reservoir.
