It depends on the setpoint of the thermostat.
It goes up while driving and down when you're idle....that's normal
Sounds like it could be a bad thermostat - not closing to allow engine to heat to normal operating temperature
mine stays just a quarter inch below midway all the time at normal temp
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.
It will usually run with a gauge temperature of around 200-210 degrees.
should be 195 to 210 normal operating temp
Speedometer, fuel gauge, and temperature gauge.
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
i just put in a new radiator and now temperature gauge reads high but their are no leaks
That's a classic symptom of a sticking thermostat.
at the beginning it will be cold, but it will warm up as you start driving
Usually the gauge in on the dashboard with all the other gauges. That way you can read it while driving.
