Ok here's the problem. I own a 92 blazer(vin w) and the temp gauge is acting up. It reads in at 240 degrees when the thermostat I just put in it is a 195 degree. The volt meter currently says the voltage is sitting at 19 while running. If you check it with a volt meter it reads in at 13.4-13.7. Could it be that the gauges are wrong or do i need to look for something else?

 

check your grounds.
