HEATER CORE HELP?

[Ron]

I HAVE FLUSHED MY HEATER CORE, SEEMS TO FLOW VERY WELL BACKWARDS AND FORWARDS AND IT DOES NOT LEAK…I ASSUMER THE HEATER CORE SHOULD BE GOOD TO GO BUT IS IT POSSABLE THAT THE LININGS ARE CORRODED AND STILL WONT TRANSMIT HEAT?? FLOW IS REALLY GOOD AND REALLY CLEAN

Topic

NO VALVE AT ALL. IM GOING WITH THE IDEA THAT THE CORE MUST BE CORRODED OR SOMETHING… IM JUST GOING TO CHANGE THE HEATER CORE AND CALL IT A DAY, IF THAT DONT WORK ILE SEND IT TO A SHOP

If the core flows good out of the vehicle a new core won’t solve the problem. There’s a reason why coolant isn’t getting to it. Maybe messy but disconnect the ingoing hose and run the engine, then work your way back

ive done that and it flows fine..How ever i think theres a leak under the intake where ford decided it was a great idea to put the return line to the pump from the heater core.. you cant see it too look but i can see that its wet down there

And to make things interesting the alternator crapped out all of a sudden…. this truck is full of demons…

Being that its a 2000 F150 he could have picked up a newer one for that price well at least here in Florida he could.

Yes, and most likely in better shape..

all things considered i would think that if it only had a small leak that i would still have heat in the heater…i mean its not leaking that bad…the leak i found was under the intake in the vally, so today ile be removing the whole intake plenum to expose the vally and the leak hopefully.

WITH DETERMINATION AND DIRTY HANDS I BRING TO YOU THE RESULT OF MY STUPIDITY!!

BACK STORY
I INSTALLED AN ENGING I PURCHASED FROM A USED PARTS PLACE IT HAD LOW KMS.. LONG STORY SHORT THE BLOCK HAD PLASTIC CORKS IN EVERY HOLE I HAD TO REMOVE BEFORE INSTALLATION…

I FORGOT ONE ON HE RETURN LINE IN THE BACK OF THE BLOCK AND THUS NOT ALLOWING FLUID TO FLOW THROUGH THE HEATER CORE

THE GOOD??
I KNOW NOW ILE HAVE HEAT BECAUSE I REBUILT THE WHOLE SYSTEM

THE BAD?
I FEEL LIKE A COMPLETE DINK!!

THANKS ALL FOR THE HELP AND SUJJESTIONS!!
