","text":"I had the same issue, same engine. You have a small leak that gets bad when the coolant pressure is high, like when climbing hills. It may take a bit to find, but have a good mechanic pressurize your system to find the leak.","replyToPid":30557}

{"replyTo":"","text":"I had a Cummins that would do that and it was the head gasket. It would do it when I was running in the mountains or had a hard head wind. It would float the head and blow the coolant out the overflow line. No leaks could be found when the truck was just at a ideal. I had to unhook the overflow line and run it where I could see it while I was going down the road. That is how I found the problem. ","replyToPid":0}
