Hey guys, I have an 81 K5 with a carb. 350 and i can't figure out how to get my temperature gauge working again. I know there is a sensor that screws into the block on the passenger side and i've replaced that. The wiring harness to that is pretty beat up but still runs power to it. The gauge inside the truck use to always be pegged on H but now it will read cold but won't move. Anyone ever had this problem? Where could I get an aftermarket gauge that works? Thanks for the help!
