Most likely, the temperature gauge's connection is loose. It is usually on the thermostat. An inoperative temperature gauge will cause most check engine lights to come on.
A low coolant level could cause the temp gauge not to read correctly. A faulty temp gauge sending unit could also be the cause. The coolant leak, you would have to find the source of the leak to determine the cause.
Could be your thermostat or your anti-freeze
The temp sending unit may be unplugged or faulty.
The gauge does not cause the heat; it only shows what it is.
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
If the temperature gauge is not working, one thing it could be besides the gauge itself is a blown fuse. Another possibility is a loose or broken wire on the gauge.Ê
Check to make sure that the temperature sensor is good. A bad sensor is commonly the cause of the temperature gauge not working.
Could be temperature sensor Could be gauge
There are several things that can cause your 2001 Ford F2 50 outside temperature gauge to quit working. The most common cause is a malfunctioning outside temperature sensor.
There are several reasons this could be:There is no coolant in the engine to trigger the temperature gauge, this will cause complete engine failure very quicklyThe gauge, wiring or sender are badThe engine temperature control thermostat has jammed open or it has been removed.
A common cause is the thermostat being stuck in an open position.
no you need to replace temperature sinding unit
Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat
A gauge glass may burst depending on the gauge itself. High temperature and pressure situations may cause the glass to burst.
Because the motor is running to hot try flushing your radiator and putting new coolant in.
The 1999 Cadillac normal coolant temperature gauge reading should be 180 degrees. A 195 degrees thermostat could be used, causing the temperature gauge to read 195.
more then likely it could be the temp, sending unit. or a bad wire to temp, sensor!!
check the power to gauge and the temperature sensor (tps). if no power broken wire or short to ground. if power to both areas bad gauge.
Probably the temp sending unit.
Head gasket. Do block test for gases in coolant
replace temperature gauge
Yes, because your vehicle will overheat.
If you temperature gauge is going up and down then you may have a problem with your sensor. You should take your car to a professional to ensure that you don't overheat your car.
