Dreaded coolant puking, a bit confused by all the info.
Hi all. I'm new to this site but have been around for awhile trying to gather as much info as I can. I currently have an 04 F-250 with the 6.0 that has 30,000 miles on it. Last weekend during a camping trip I opened the hood and noticed the coolant level was low (about 1" below line) and there was coolant residue on the underside of the hood. I filled the overflow with aprox. 1/2 gall. of water. to get back home. Checked again at home, this time 1/2" low. There doesnt seem to be any white smoke from the exhaust, no oil in the coolant, oil is not milky, no loss of power that I can tell, no apparent leaks around the heads that I can see.
My gut tells me it might be the EGR cooler/oil cooler. I talked to the service tech at the dealership I have the truck serviced at and he told me that 9 out of 10 times coolant puking is a sign of bad head gaskets. IDK!! I've read enough on this site and others to make my head hurt. What do you guys think?
