General Maintenance<br />
Bleeding the Cooling System<br />
MAINTENANCE<br />
CAUTION<br />
If coolant flow becomes restricted or plugged, coolant loss, air lock<br />
or engine damage may result. Most cooling systems are equipped<br />
with a filter that should be periodically inspected or replaced.<br />
1. Remove the pressure cap and fill the coolant bottle with properly<br />
mixed coolant to the maximum mark.<br />
2. Elevate the front end of the machine slightly to aid in bleeding of the<br />
heat exchangers.<br />
3. Remove the bleed screw from the water outlet manifold and/or the<br />
thermostat housing. Allow the coolant to bleed through the system<br />
until it runs out the bleed holes. Reinstall the bleed screw into the<br />
manifold.<br />
4. Add coolant to the coolant bottle to the maximum mark.<br />
5. Start the engine and run at a fast idle for two to three minutes. Loosen<br />
the bleed screw occasionally to purge any trapped air.<br />
6. Stop the engine and check the coolant bottle level. Fill as required.<br />
7. Feel the heat exchangers under the running boards. If the system is<br />
bled properly, they’ll be warm to the touch. If they’re not, repeat step<br />
5. Lift the front of the machine slightly to assist in the bleeding.<br />
8. Replace the pressure cap and carefully lower the front end of the<br />
machine.<br />
