    Hi everyone. I have a 2003 Pete 379 and recently my water temp and oil temp seem to be stuck. They start the day at about 180 degrees then climb to over 200 and stay there. My trans temp gets to about 195 when shifting a lot. Any help would be appreciated.

    simple things first, check all dash/body grounds. something could be broken, or loose.

    Thanks buddy. So much spaghetti back there with 18 gauges. I need a day to go through it. Better than burning the truck down.

    I would start by checking the ground leads to the faulty gauges.

    I found it. Bad ignition to the gauges. Couldn't actually find the break so I ran new wires. Everything works fine. Thank you for the come backs fellas
