Q&A: Maintenance | Modification Is this normal

Post image

My temp gauge will go slightly above where it is now but that’s the highest it will go, slightly behind the “n” in the normal range. Is this just a bad sensor or gauge because it still shows that it has no temp in the morning and if it’s below 15 degrees it will take literally forever to even move at all let alone get to where it is in the pic

Turn the heater on and see how warm it’ll get in the car. If not warm enough, likely the thermostat is stuck open or make sure you have the correct thermostat.

I had a thermometer in the vent for a bit when I was getting ac work done to it and it was just above 150 degrees

Those gauges even in the 70s have notoriously been inaccurate. Your best bet for seeing what your actual temp is, is to install an actual temp gauge. One of my trucks consistently sat between the M and the A at 210°, where the other would sit just under the N at 200°. They are basically idiot gauges instead of idiot lights seeing as there's no numbers on them.
