Cooling System

Bleeding the Cooling System

Bleed the cooling system at the intervals outlined in the Periodic Main-

tenance Table beginning on page 72. Perform the bleeding procedure

when the engine is cold.
1. Remove the pressure cap and fill the coolant bottle with properly

mixed coolant to the 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 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 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.
