mixed coolant to t he maximum mark.
2. Elevate the front end of the machine slightly to aid in bleeding of
the heat exchangers.
3. Remove the bleed screw from the water outlet manifold and/or the
thermostat housing. Allow the coolant to bleed through the system
until it runs out the bleed holes. Reinstall the bleed screw into the
manifold.
