Help! I accidentally pulled off my engine temp needle wen i putting on a gauge face....now its not working, any fixes or do i have to get a new one?

 

if you disconnected a gear inside the temp gage then you might want to get a new one. When i did my gauge, i held it with a small pair of needle nose pliers and popped it off with my fingers. Mine still works. If it's not overheating then don't worry so much. Just stop at an auto parts store and pick an aux gauge for under 50 bucks
