I have my 2008, Ford 6.4 at the Ford garage. I took it in because it was puking coolant while towing my 5th wheel. Ford garage did the compression test and checked the computer to see if egr cooler. They said everything was fine with the egr cooler, but problem was a head gasket. Cab was lifted this past week and $1200 worth of ford parts were replaced. This was on the left side. Everything was put back together and cab re-attached. Service manager took truck out to test drive today and said he drove the truck 80 mpg and the truck was still leaking anti freeze. Right now they are waiting to hear from Ford to find out what else they can try? I asked him if it's not the egr cooler, what else could it be. I suggested maybe the gasket was pinched or installed improperly, but he did't think so. The garage has had the truck since last Wednesday and the parts came in this past Monday. Can anyone give me any ideas of what could be the problem. I'm starting to get really nervous about this garage??? I am not at my local Ford garage. I'm 400 miles from home and driving a rental car. The truck has 109,000 miles on it. I've always had all required maintenance performed on it at my local ford garage. No tuners or anything like that on truck because I didn't want to screw with warranty. No warning lights or excessive temperatures shown while driving. Getting to be very frustrating and expensive.
