Bleeding the Cooling System
If the pressure cap needs replacement, contact your dealer for the
correct part. Use of a non-standard pressure cap will not allow the
recovery system to function properly.
1. Remove the pressure cap and fill the coolant bottle with properly
mixed coolant to the FULL COLD mark.
2. Elevate the front end of the machine slightly to aid in bleeding of
the heat exchangers.
3. Add coolant to the coolant bottle to bring the level to the FULL
COLD mark.
4. Start the engine and run at a fast idle for two to three minutes to
allow further bleeding of air.
5. Stop the engine and check the coolant bottle level. Fill as required.
6. 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 4. Lift the front of the machine slightly to assist in the
bleeding.
7. Replace the pressure cap and carefully lower the front end of the
machine.
Steam and hot liquids will cause serious burns to your skin.
Never bleed the cooling system or remove the pressure cap
when the engine is warm or hot.
WARNING
If coolant flow becomes restricted, coolant loss, air lock or engine
damage may result. Periodically inspect and/or replace the cooling
system components as needed to prevent restricted coolant flow.
