83 MAINTENANCE General Maintenance Engine Cooling - Liquid Cooled Models Bleeding the Cooling System correct part. Use of a non-standard pressure cap will not allow the cooling system to function properly. 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. 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 exchanger on the rear end of the tunnel. If the system is bled properly, it will be warm to the touch. If they’re not warm, repeat step 5. 8. Reinstall 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 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. CAUTION |
