Nice caps there, and if it's pegged I believe you should try checking the ground wire
I had asked about my temp gauge because mine doesn't move at all

Then while you are doing that have someone inside the cab and watch the gauge. If the needle goes up when you ground it, then it's probably the sender, if it doesn't move then it could be the gauge.
THANKS FOR THE INPUT GUYS. WAS WONDERING IF ANY OF YOU HAD A THOUGHT ON THE SECOND PART OF MY QUESTION ABOUT SOMEONE TELLING ME THERE IS ANOTHER TEMP UNIT THAT ALSO NEEDS CHANGING? IS THIS TRUE? IS THERE ANOTHER TEMP UNIT ALSO ON THE 7.3 ENGINE ?
