how to install water temp gauge automotive

When installing the instrument water temp gauge automotive , you can choose to put it directly on the workbench. As for the wiring from the engine room to the cab, I have searched for a long time, and found that the simplest and nearest route is the rubber sleeve position under the lower left corner of the glass. You need to remove the sound cover and the A pillar cover, and then you can see a water drain rubber sleeve, pull it out, drill holes and thread it. Pay attention to the position where the wire is not exposed to rain.

Because the automotive instrument is equipped with the battery voltage monitoring function, it needs to be connected to the regular power supply. It is too troublesome to take power from other locations, so it is convenient to directly connect the battery, which also brings some risks. Once a short circuit occurs, the battery will burn. Many vehicles have spontaneous combustion due to inadequate line construction, so I connected a 5A fuse to the line and fixed it in a small box according to the principle of safe modification, Fix the box on the battery.

At this time, the thermostat is turned on, the car is stopped, and the water can be drained. Wear gloves and pull off the lower pipe. Note that the temperature is too high to be scalded. Use a high-pressure air gun or hair dryer to blow from the auxiliary kettle until no water flows out of the lower pipe. Pull off the warm air tank pipe and blow with an air gun until no water flows out of the lower pipe. Pull off the upper pipe and blow from both ends. Until there is no water flowing out of the sewer pipe, then your antifreeze is completely discharged. Take a little new antifreeze and pour it into each position to wash the residual old antifreeze, and then blow it clean.

Next, all the pipes shall be restored and installed. If possible, the auxiliary kettle can be washed, and the carburetor can be used to spray and dry the water for once. Open the engine bleed screw and the warm air tank bleed screw to the half open position to help the cooling system bleed! Add new antifreeze to the auxiliary water bottle to fill up! Start the engine and the two air release screws will bubble.
