Cooling System Care
The series- flow, pressure-type cooling system consists of the radiator, fan, water pump, Thermostat, engine coolant passages, and all necessary hoses, connections, and fittings. A coolant pressure of 13 pounds per square inch is retained in the system by a vented, spring-loaded radiator cap. This pressure permits the engine to operate at high temperatures without losing or boiling out the coolant. Full-length water jackets in the engine help to reduce internal friction and increase engine efficiency.
The centrifugal, high-capacity water pump circulates the coolant through the system. The pump shaft is supported by a double-row ball bearing, which is permanently lubricated and sealed.
The positive-action thermostat regulates the temperature of the engine coolant without being affected by pressure variations in the system.
