Towing overheating

[wlsmithjr1960]

Hello, The family went to Myrtle Beach(a 3 hr drive), this past weekend, everything was going great the first 20 miles, was pulling some hills and 2005 FX4 Crew cab with 6.0 automatic started overheating when turbo boost went to between 20 and 30 and there was a squeaking noise when pressed on pedal backed off and temp went back to normal. It never went up again unless Turbo Boost went above 20. Checked antifreeze level was fine wasn't pucking, cooling fans were working,no oil in coolant and oil level was good. I was towing a 9,000lb travel trailer with a golf cart in the bed. Any ideas would be greatly appreciated. Located in Trinity, NC traveled Hwy 64, Hwy 220, Hwy9, Hwy 38, Hwy 501 and made it there on Hwy 544http://www.powerstroke.org/forum/images/smilies/icon_ford.gif

It sounds like the EGR cooler might be starting to take a crap on you. It can leak exhaust into the coolant and vice versa.

Could also be a faulty gauge/sensor. Were you running the A/C?
