Re: Temp Gauge issue
These things can be troublesome for sure. I guess using any aftermarket brand sender or thermostat can cause the gauge to read erroneously. I had an 85 blazer, all stock, the gauge read normally until I changed the thermostat. It then began going nuts like yours. Upon cold start up the gauge climbed and didn't stop until it pegged out. All I did was change from a 185 stat to a 160. I bled until I was sure all the air was out and it still read the same. I changed the thermostat, sender and even the gauge.
I put the 185 back in and it once again read normally.
Apparently changing the range it was designed to operate in doesn't always work well.
