Well, after removing the temp gauge from the truck(what a pain in the....), I started drilling out the tiny rivets holding the gauge face on. Apparently, while drilling the second rivet, I applied to much pressure on the unit and the needle went to 180 instead of 100. Is it possible to bend the coil back so the needle rest near 100? Is there a way to test it out of the truck or should I just order a new one?
