1. Schematic
Schematic2. Specifications (standard) INSPECTION
Inspection points1. Water pump Check the impeller and shaft for rotation. If they do not rotate freely or have noise, replace the water pump assembly.
Checking water pump2. Thermostat (standard) Hang the thermostat in the pan of water as shown in the illustration. The thermostat must be below the surface of the water and its must be away from the sides of the pan. Heat the water uniformly in the pan and measure a temperature at which the valve starts opening and a temperature at which the valve lift (distance) is 8 mm (0.3 in.). Replace the thermostat if defective.
Water in the pan is hot. Any contact can cause severe burns.
Testing thermostat3. Thermoswitch (standard) Hang the thermoswitch in the pan of oil with its temperature sensing end below the surface of oil and measure the resistance while heating the oil as shown in the illustration. If the resistance is incorrect, replace the thermoswitch.
Oil in the pan is hot. Any contact can cause severe burns.
Testing thermoswitch4. Thermounit (standard) Hang the thermounit in the pan of antifreeze with its temperature sensing end below the surface of antifreeze and measure the resistance while heating the antifreeze as shown in the illustration. If the resistance is incorrect, replace the thermounit.
Antifreeze in the pan is hot. Any contact can cause severe burns.
