Cooling System

"Walter C. Avrea, the owner of patents 3, 601, 181 and RE 27, 965, has granted Ford Motor Company rights with respect to cooling systems covered by these patents."

 WARNING: TO AVOID THE POSSIBILITY OF PERSONAL INJURY OR DAMAGE TO THE VEHICLE, DO NOT OPERATE THE ENGINE WITH THE HOOD (16612) OPEN UNTIL THE FAN BLADE HAS BEEN FIRST EXAMINED FOR POSSIBLE CRACKS AND SEPARATION.

The cooling system operates as follows:

• Coolant flows through the radiator tubes and is cooled by air passing over the cooling fins assisted by the engine cooling fan.
• Coolant is then circulated from the radiator outlet tank (8054) through the water pump (8501) and into the cylinder block (6010) to complete the circuit.
• Coolant expands as the temperature and pressure rise in the system.
• When the limiting system working pressure is reached, the pressure relief valve in the radiator cap (8100) is lifted from its seat and allows coolant to flow through the radiator filler neck and the radiator overflow hose (8075) into the radiator coolant recovery reservoir (8A080) .
• The radiator cap has a rubber seal on the underside to prevent leakage.
• When the system temperature and pressure drop, the coolant contracts in volume and the pressure in the radiator (8005) is reduced.
• The coolant in the radiator coolant recovery reservoir will then flow back into the radiator through the vacuum relief in the radiator cap .
