Where is the Wuling Rongguang Water Temperature Sensor Located?
2 Answers
Wuling Rongguang water temperature sensor is located at the water outlet of the engine's upper hose, on the left side of the engine (the side where the battery is installed). Above the front oxygen sensor, there is a three-wire sensor with a black housing - that's the water temperature sensor, which can be removed using a 19mm socket with an open-end wrench. Introduction and working principle of automotive water temperature sensor are as follows: Introduction to Automotive Water Temperature Sensor: The interior of the automotive water temperature sensor contains a thermistor. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. It is installed on the water jacket of the engine block or cylinder head, in direct contact with the coolant, thereby measuring the temperature of the engine's cooling water. Working Principle of Automotive Water Temperature Sensor: The electronic control unit detects the temperature of the engine's cooling water based on this resistance change - lower temperature results in greater resistance, while higher temperature results in smaller resistance. The ECU uses this temperature reading as a correction signal for fuel injection and ignition timing.
I remember driving the Wuling Rongguang for several years. The water temperature sensor is usually located above the engine cylinder head or near the thermostat housing. When you look for it yourself, open the engine hood and look from the front of the car. The sensor is where you see a brass or plastic plug on the cylinder head. Don't worry about it being hard to find. First, check if the fuse box is functioning properly. A faulty sensor often causes inaccurate water temperature gauge readings or engine overheating. It's safer to stop and rest for a few minutes before checking again. I recommend regularly changing the coolant to keep the system healthy. If any issues arise, go to a repair shop immediately to check the wiring. Don't let a small oversight ruin the engine. I've replaced it myself twice—it's easy and hassle-free.
