Temperature guage on 79 chevy g20 goes haywire, back and forth between hot and cold
10

Asked by Vinnymac11 Mar 02, 2017 at 05:38 PM about the 1979 Chevrolet Chevy Van

Question type: Maintenance & Repair

Have replaced the thermostat twice and guage keeps doing the same
craziness, back and forth. If I'm up to high speed on freeway, the guage levels
off on cool. Sometimes, as Im driving along a street, it'll level off to cool. Other
times, its a back and forth thing. If it idles, sometimes it's okay and not moving
and other times it's all over the place. What could be causing this?
