Bleeding the Cooling System
SurgeTankModels
1. Remove the pressure cap and fill the coolant bottle with properly
mixed coolant to the maximum mark.
2. Elevate the front en d of the machine slightly to ai d 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 to the coolant bottle to the maximum mark.
5. Start the engine and run at a fast idle for two to three minutes.
Loosen the bleed screw occasionally to pur ge 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 l ower the front end of the
machine.
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.
