2005 GMC 2500HD overheating
This heat wave in the West is causing havoc. The truck is overheating without the 5th wheel on...and I need assistance. Engine temp is just above 210, and the tranny temp is right about 200. I'm sure ...

Can you hear the cooling fan lock in and if so is it locking up for long times or just in and out. Are you slow speed around town or highway speed for good air movement. The temp gauge on these GM's are not the most accurate but unless the fan is staying locked up for a long time I would say you don't have a problem.
