Install mustang water temp gauge , find the water supply pipe, which is generally 28mm, which is obvious in the carriage. Cut the opening at the appropriate position as close as possible but not more than the length of the tee. Install the tee into the water supply pipe, tighten it with the lock catch, screw on the sensing head, apply sealant to the gap, thread the wire of the water temperature gauge from the left part of the driver's seat to the engine compartment and connect it with the sensor, connect one of the water temperature gauges to the middle one of the cigarette lighter, and connect the other two casually to form a loop, so that it can automatically cut off power after pulling the key.

The water temperature sensor is installed on the water channel and water tank of the car, the old Honda is installed under the distributor, and the temperature control switch is installed on the water channel.

The function of the first type of water temperature sensor is relatively simple, that is, through the change of its internal resistance to change the current through the change of the resistance of the sensor to drive the change of the water temperature gauge, and indirectly tell people the working temperature of the engine. Second, the water temperature sensor has no change in structure, but its function is to provide an analog signal of temperature change to the engine control unit. Its power supply voltage is a 5V power supply provided by the control unit, and the signal returned to the control unit is a linear change signal of 1.3v-3.8v. The main function is to tell the engine control unit the current temperature. On the contrary, its signal is very important to the control unit.

The main reason is that the engine has different working methods at different working temperatures. For example, when the temperature is below 86 ℃, the engine needs to spray 10% more oil than the normal temperature, in order to make the engine heat up quickly and reduce the low-temperature wear of the engine. After the temperature rises to above 86 ℃, let the engine spray less oil, and let the temperature regenerate slowly. So its role is very important. If he has a problem, he provides the wrong signal to the engine control unit, such as the engine low temperature signal when the car is hot. Does your car spray more oil, so it looks a little waste oil.
