What Causes the Temperature Gauge to Stop Moving?
2 Answers
The reasons for the temperature gauge not moving are as follows: 1. Wiring issues: The power wire of the temperature gauge is broken, the heating coil of the temperature gauge is burnt out, or the heating coil of the temperature gauge sensor is burnt out or the contact is poor. The wiring of the temperature gauge sensor is loose or broken. The voltage regulator supplying stable power to the temperature gauge circuit is damaged. 2. Thermostat: Check if the heater is blowing hot air. Then feel if the temperatures of the upper and lower radiator hoses are the same. It is recommended to check if there is a thermostat. After confirming there are no issues with the thermostat, consider the sensor, wiring, and temperature gauge. It is likely that the thermostat is damaged, remaining in the open position, causing the coolant to continuously circulate in a large loop.
I've been driving for over a decade, and it's quite common for the water temperature gauge to stop working. It's most likely due to a faulty coolant temperature sensor – that little device stuck near the engine to measure temperature can rust or fail over time. Another possibility is an internal instrument cluster malfunction, like a stuck needle or scrambled electronic display. Also, unstable wiring connections such as loose plugs or aged/broken wires can prevent signal transmission. Don't forget to check the corresponding fuse in the fuse box – if it's blown, try replacing it with a new one. From my experience, neglecting this issue may lead to engine overheating or even cylinder head gasket damage, which would be costly. So during routine maintenance, always ask your mechanic to inspect the cooling system – prevention is key for worry-free driving.
