Hello four eyed family, getting ready to do a safety on my 80 fox and noticed that my temp gauge doesn’t read properly. When it gets warm the gauge only goes up to the C and no more.

I grounded the sender wire and the gauge does the same thing only up to the C. I also noticed that it takes a long time to get there is that normal?

Anyways to the main question. Which is bad my sender, sensor, or guage. Anything helps!
