The 12V/24V peterbilt water temp gauge is hookup to the key and then connected to the water channel. External water temperature gauge set, with instrument, harness, sensor and other accessories. The body of the water temperature gauge is self luminous on a white background, which is suitable for observing water temperature at night.

There are four lines in total, one of which is a three line instrument. The focus is on the four line instrument. The four lines are red (open key 12V/24V), black (ground wire), blue (signal line), and white (power is available when the small light is turned on). The three line instrument is short of white lighting line.

The peterbilt engine water temp gauge is used to indicate the temperature of the engine coolant. The coolant temperature signal is provided by the engine coolant temperature sensor installed on the engine cylinder head. When the peterbilt engine works normally, the displayed value should be 80-100 ℃. When the engine coolant temperature reaches 97 ℃, the cooling fan runs at low speed. When the peterbilt engine coolant temperature is lower than 94 ℃, the cooling fan stops running. When the engine coolant temperature is higher than 105 ℃, the cooling fan runs at high speed. When the engine coolant temperature is lower than 101 ℃, the cooling fan stops running.

Our water temperature gauge is good in quality and cheap in price, so you can install it yourself. Remove the sensor plug of the original vehicle of the water temperature on the thermostat, install a new one, and then go through the wiring. Pay attention to the 12v and 24v water temperature gauges. Remember to connect the red positive pole to the red line of the water temperature gauge, and finally fix the water temperature gauge to the dashboard! The hookup method of the peterbilt water temp sensor is as follows: first, use a special tool to remove the thermostat, then pull out the clip of the water temperature sensor, then remove the water temperature sensor, and finally replace the thermostat with a new sensor. If the water temperature gauge sensor is damaged, it will cause the water temperature gauge to remain at the same height all the time, resulting in the wrong judgment of the owner. If the water temperature sensor is damaged, it needs to be replaced in time, otherwise the driving safety of the vehicle will be affected.
