I know a young man that owns his own business works hard, he is having some issues with his truck. Thought I would ask all of you smart guys on here.
2009 Silverado 2500 6.6 turbo diesel
248k miles
It overheats, turns my AC off, and I have no heat during the winter time
It overheats every time I drive it. I haven’t lost power, hasn’t affected the driving at all. I put new radiator, New thermostats, New coolant temp sensor. I have stopped to check the engine when temp gauge said was running hot, and it’s not actually hot at all. That’s why I changed the sensor, I thought maybe it was throwing false code but it wasn’t that either. Cools off quickly and is drivable Again, or When I hit like 55 mph consistent but then the gauge goes back down and the AC turns on again. It does this under when hauling, but also does it when driving just the truck itself.
I am thinking maybe exhaust leaking into cooling system.
