I warmed up the eng (400 '67 C-10) and turned on the blower and all I got was cold air...I know the water pump is working cause the eng runs at the proper temp and you can plainly see by the gauge when the 'stat opens but for some reason there is no warm water getting to the heater core...some po put a valve on the water line going to the heater core but it turns freely like it is opening?...the temp of the line it'self is cool to the touch even when the motor is warm and the lever seems to be all the way over for heat ?
it's like nothing is going to the heater core...
guess I need to pull the line to see what's up? just wondered if anybody had run into anything like this | | |

Wearever the resriction is will be colder on the other side. If the hose going in to the heater is hot & the one comeing out is cooler the heater core may be stopped up. Also make shure the coolant in the radiator is clear full. If it is a little low it can get poor circulation.If all the heater hoses are hot you could have a heater door not functioning.

Could be something simple as a new radiator cap..
Happened to me once, just before I was about to try to get the heater core out..

Sounds like your valve is broken in the closed position, I got a modern replacement valve for $12 or so at my local auto parts store. | | |
