Isn't that special. You should change your name to Kenworth gossling.

ok guys same problem with a new twist...lol I changed my radiator out the weekend and put a new cap on and new coolant also..now I still have the sound of water running when moving but now the heat works sometimes...if I sit with the truck running and the fan off then turn the fan on it blows hot or warm air while driving it blows just enough to defrost the windshield ....now could this be from the air pocket some of the guys was talking about??? its just crazy how this stuff works now days...

Sure sounds like air in the system.

guess ill have to try and clear the system of air..any tricks ..I know 1 guy said he parks on a hill run the motor up for a while anything else I can try or do I need to just buy a tool...

You could do it the easy way, raise one of the heater hoses above the radiator cap. put a flush tee in it and fill it the last little bit from the flush tee. Leave the cap on it while doing this.

well I had a freeze plug come out the driver side head lost all the new coolant so I had to repair that..anyway I ordered a new surge tank while at it..with all the coolant and water out the system I changed the heater core hoses around to flow the opposite way then I took the plug out so that all the air would come out as I refilled the system...I filled the system and watched the bubbles as they came out the hole and then I started the truck to let it warm up as it did I filled the system til the coolant was running out the bleeder hole I tighten it up and top the system off...so now no running water sounds and the heat is so hot im loving it..thanks guys for all the help..now if I could get this transmission to be fixed .lol

What about just doing the refill with the truck jacked up in the front?
