*Okay Ive been watching this for a day or so now...all good advice and tips so far. Part that bothers me is when Jeremy ran the truck for a half hour and continuous bubbling in the radiator. Sure sign that something is pumping air into the system and last I checked the only thing capable of overcoming the cooling systems pressure is engine compression. My original head give me plenty of warning by bubbling the radiator. Next sign was coolant coming from the overflow bottles overflow tube. It took all of about a month to finally give up the ghost. Turned out to be erroded coolant passages along the exhuast side..yup all 4. When I cracked a head back in summer of 2002. The only sign of any problem was slightly rough idle on startup. Didnt think much of it since it cleared up once the engine reached temperature. A few days later I had a hydrolock situation...took 3 keyhits to fire. So I pulled the plugs and found #3 and #4 to be extremely clean. Ended up being cracks in both those chamber between the seats.
Hope this aint discouraging, just keep an eye on things and make preparations for pulling the head off and getting it checked out.
