autometer water temp gauge install

With the severe warming of the weather, many old cars are boiling, and most models are on the highway. If there is a vehicle failure at 120km / h, no one must want to happen. In the eyes of most drivers, the water temperature gauge is optional. Others responded that "if there is a failure, the vehicle will alarm, whether or not", but the medium and high-end models basically have water temperature gauges, In this way, you can see the basic information of the model. Today, I'll teach you to simply install a water temperature gauge.

The installation of water temperature gauge is various. I recommend a simple, beautiful and unobstructed method. Calculate that the information is refreshed every second and a half. That's good. Here's the point. It takes less than ten minutes to install, and the cost is less than $12. And it doesn't hinder the perspective at all, and it's beautiful.

External water temperature gauge set, with instrument, harness, sensor and other accessories.
1、 Find the water supply pipe, which is generally 28mm. It is obvious in the carriage. The length of the cut opening at the appropriate position shall be as close as possible, but not more than the length of the tee.
2、 Install the tee into the water supply pipe and tighten it with the lock catch. Screw the sensing head on the small opening and apply sealant to the gap.
3、 Thread the line of the water temperature hand from the left part of the motorist's seat to the machine cube and connect it with the detector.
4、 Connect one of the water temperature gauges with the one in the middle of the cigarette lighter, and connect the other two randomly to form a loop. After pulling out the key, it can automatically cut off the power.

Be accomplished. After installing the water temperature gauge, you can observe the working state of the machine at any time. If the temperature reaches 98 or 99 degrees and the electronic fan does not start, turn off the engine and open the machine cover to have a rest. It is best not to turn on the air conditioner for a long time in summer, which is bad for the car and people. If it doesn't look beautiful enough, you can also add turbine pressure gauge, tachometer, etc. Our company sells these auto meters.

In addition, the power supply of the water temperature gauge comes from the power regulator. It is not allowed to connect it directly with the power live wire on the vehicle, otherwise the reading of the indicator will be inaccurate and even the instrument will be damaged. Do not connect the wire between the water temperature gauge and the sensor to ground for fire test, so as to avoid burning out due to overheating of the heating coil. The sensor shall be well sealed to prevent the sensor from failure due to water leakage. If the water temperature gauge and sensor of the vehicle have been matched and damaged, the water temperature indicator or sensor of other models cannot be installed, and new parts of the same model should be replaced. Check the internal resistance of the water temperature indicator. Check the resistance of the heating coil with the ohm block of the multimeter. The value should be (36.6 + 1)Ω.
