Either the temperature sending unit or the gauge or the wiring in between is bad. I would put my money on the sending unit if the wire harness is plugged in and has no apparent damage.
What are you talking about? My temperature gauge works fine. Though, if it wasn't I would check the temperature sending unit.
The sending unit may be faulty. The year, make, model and which gauge would help.
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
Check to make sure that the temperature sensor is good. A bad sensor is commonly the cause of the temperature gauge not working.
no you need to replace temperature sinding unit
Bad gauge or defective coolant temperature sensor
A temperature gauge on a 1992 Chevy van may not work due to several reasons, including a faulty temperature sending unit, a broken gauge, or damaged wiring and connectors. Additionally, low coolant levels or issues with the engine's cooling system can prevent the gauge from reading accurately. If the gauge itself is malfunctioning, replacing it or the sending unit is often necessary to restore proper function. Checking the vehicle's fuse related to the gauge may also be a good first step.
you need a newvoltage reducer
The temperature gauge in a 2000 Daewoo Lanos may not work due to a faulty temperature sensor, which provides readings to the gauge. Additionally, there could be issues with the wiring or connections between the sensor and the gauge, leading to a lack of signal. A blown fuse or a malfunctioning gauge itself could also be potential causes. Checking these components systematically can help identify the issue.
If it gets to hot the thermostat wont work. you need to repace it and the gauge will work again.
because the engine in that car does not cool down
