Refilling

REFILLING COOLING SYSTEM

1. Tighten the radiator drain and the cylinder block drain plug(s) (if removed). Tighten the engine drain plug to 30 Nm (22 lbs. ft.).
2. Fill system using a 50/50 mixture of ethylene-glycol antifreeze and low mineral content water Description and Operation. Fill radiator to top and add sufficient coolant to the coolant recovery pressure container to raise level to COLD MINIMUM mark.
3. With heater control unit in the HEAT position, operate engine with container cap in place.
4. After engine has reached normal operating temperature, shut engine off and allow it to cool. When engine is cooling down, coolant will be drawn into the radiator from the pressure container.
5. Add coolant to pressure container as necessary. Only add coolant to the container when the engine is cold. Coolant level in a warm engine will be higher due to thermal expansion. To purge the cooling system of all air, this heat up/cool down cycle (adding coolant to cold engine) must be performed three times. Add necessary coolant to raise container level to the COLD MINIMUM mark after each cool down period.
