Replace the “temp switch”. It’s on the right side of the block, in between the exhaust headers, it’ll have a single green wire going to it from past the alternator. They cost like $20, and it’s an easy replacement. Be sure to get the “temp SWITCH” and NOT the “temp SENSOR”.

What should I do if my Guage sensor is not working?

Your guage should peg out. If it does both of these correctly, then you need a new temp sensor. If it does anything else with either of these two tests, then it’s a dash cluster/guage problem. Check your thermostat first! If your thermostat is bad, the engine will never warm up, and that can make it look like the gage is bad.
