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
should be 195 to 210 normal operating 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.
mine stays just a quarter inch below midway all the time at normal temp
It will usually run with a gauge temperature of around 200-210 degrees.
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
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.
195 to 210 what temperature thermostat do you have
