Hey guys. I have a 04 with 03 motor 6.0 powerstroke with 140k on it. I just recently got had cracked heads and cracked injector cups(smell of fuel in coolant) so I spent the money and got new heads, studs, egr delete, and a ssx turbo. I put 155/30s in the truck about a year ago and so I got the truck back from getting motor work done and drove it around for a little and no leaks. Then when I got home I went inside for about 30 minutes and when I came back outside there was coolant everywhere coming from under a pulley that's below the altnater pulley. Could it possibly be the intake manifold donut o-ring?? But why no leaks till I shut it off??
