MAINTENANCE
Cooling System
Bleeding the Cooling System
Use of a non-standard pressure cap will not allow the recovery system
to function properly. If the pressure cap needs replacement, contact
your dealer for the correct part.
WARNING
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.
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 the
recommended coolant to the “FULL COLD” mark.
2. 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.
3. Add coolant to the coolant bottle to the “FULL COLD” mark.
4. Start the engine and run at a fast idle for two to three minutes.
Loosen the bleed screw occasionally to purge any trapped 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.
7. Replace the pressure cap.
