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." Â WARNING: NEVER REMOVE THE PRESSURE RELIEF CAP UNDER ANY CONDITIONS WHILE THE ENGINE IS OPERATING. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE COOLING SYSTEM OR ENGINE AND/OR PERSONAL INJURY. TO AVOID HAVING SCALDING HOT COOLANT OR STEAM BLOW OUT OF THE COOLING SYSTEM, NEVER REMOVE THE PRESSURE RELIEF CAP FROM A HOT DEGAS BOTTLE. WAIT UNTIL THE ENGINE HAS COOLED, THEN WRAP A THICK CLOTH AROUND THE PRESSURE RELIEF CAP AND TURN IT SLOWLY ONE TURN (COUNTERCLOCKWISE). STEP BACK WHILE THE PRESSURE IS RELEASED FROM THE COOLING SYSTEM. WHEN CERTAIN ALL THE PRESSURE HAS BEEN RELEASED, REMOVE PRESSURE RELIEF CAP (STILL USING A CLOTH). Â 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 (8600) HAS BEEN EXAMINED FIRST FOR POSSIBLE CRACKS AND SEPARATION. This section covers cooling system diagnosis and service, cooling system component removal, disassembly, assembly, installation, service procedures and specifications. The coolant system operates in the following manner: Ã Â Â Coolant flows through the radiator tubes and is cooled by air passing over the cooling fins assisted by the mechanical cooling fan blade, and auxiliary electric cooling fan motor and fan blade. Ã Â Â Coolant is then circulated from the radiator outlet tank through the water inlet (in the oil filter adapter (6881)) to the water pump (8501) and into the cylinder blocks (6010) and cylinder heads (6049). The coolant then returns to the radiator (8005) through the radiator inlet tank to complete the circuit. Ã Â Â Air is removed from the system by passing coolant to the degas bottle where this air is separated and the coolant returned to the cooling system. Engine Cooling System
