Bleeding the Coolin g System
CAUTION
If coolant flow becomes restricted or plugged, coolant loss, air
lock or engine damage may result. Most cooling systems are
equipped with a filter that should be periodically inspected or
replaced.
1. Remove the pressure cap and fill the coolant bottle with properl y
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.
4. Add coolant t o the coolant bottle to the maximum mark.
5. St art the engine and run at a fast i dle for two t o t hree minutes. Loosen
the bleed screw occasionally to purge any trapped air.
6. Stop the engine and check the coolant bottle level. Fill as required.
7. Feel the heat exchangers under the running boards. If the system is
bled properly, they’ll be warm to the touch. If they’re not, repeat step
5. Lift the front of the machine slightly to assist in the bleeding.
8. Replace the pressure cap and carefully lower the front end of the
machine.
