Gents,
I have a 2008 Chevy silverrado 6.6 L Diesel engine with 47000 miles and I pull a 25ft trailer that weighs 6600 lbs, InI the past few days the temp gauge has started to rise way past 210 degrees, of course my first though is to turn off or down the AC, and I have done this and it returns to the normal operating temp. But if i completely turn off AC, it will pretty close to 210 degrees. This is my company truck and its own the road almost 7 days a week. I'm at a lost for what could be the issue, I hope it's not a cracked head. Thanks
