My 92 wrangler 2.5L temperature gage always reads around 100, has done this since I have owned it. Before I put in an aftermarket gage, would like to get this gage operating correctly if at all possible. Really would appreciate any information anybody can pass along to get the gage working, bothers me not knowing the correct running temperature in case it would over heat sometime. All I am working with is an aftermarket repair manual which is good but doesn't cover allot of the detailed stuff. Thanks in Advance . . .
