DESCRIPTION:
The engine cooling system is a liquid cooled type, using a mixture of water and ethylene glycol (antifreeze) as the coolant.
The coolant recovery system consists of a tank and two hoses. The coolant recovery tank is located on the left front inner fender apron. It is a translucent plastic container with a black nylon reservoir cap. The coolant from the radiator flows into the coolant recovery tank. As the engine cools, the excess coolant flow out through the top of the radiator by gravity back to the coolant recovery tank. This prevents over pressurizing of the radiator and the coolant system.
OPERATION:
The coolant recovery system operates under normal pressure of 13 to 15 psi (90 to 105 kpa). When the engine is cool and the coolant is contracted. The coolant drawn into the radiator from the coolant recovery tank. When hot and coolant begins to expand due to the increase of temperature. The pressure relief valve in the radiator cap open and the coolant flows through the upper hose to the coolant recovery tank.
The coolant recovery tank provides a low pressure reservoir for the excess coolant. The tank holds about 1 liter (0.3 gal.) of coolant. The coolant is returned to the radiator by the action of the suction applied by the circulating waterpump.
The suction hose to the waterpump is located at the bottom of the coolant recovery tank.
