TITLE ADDITIONAL WATER TEMPERATURE SENSOR FOR ENGINE FAN

To improve cooling system performance, one additional water temperature sensor has been installed to control the engine cooling fan separately. The
additional water temperature sensor is installed at the water inlet area (see figure below). The existing water temperature sensor controls the A/C
amplifier assembly.
