Quick heater core - hose hook-up question

[DiggetyDan]

Hi all, I replaced my heater core (and rebuilt the box with a chevy blower - thanks Hotwheels - http://www.classicbroncos.com/forums/showthread.php?t=54371&highlight=chevy+heater

I had the heater core bypassed for the summer but now that winter's rolling around I need to hook it back up and sure enough forgot which hose goes to which part of the core. Does it matter? And if so anyone know? It looks like the one that comes out of the top of the engine goes into the pipe towards the outside of the bronco and the one that comes out of the top of the engine a little bit lower and forward goes into the pipe towards the center of the truck.

Thanks for the help.

The core doesn't have a direction per se so you can hook it up any way you want but original is the other way around from what you describe. I take it you don't run the valve? Lot's easier than bi-annual hose fumbling.

Thanks Sea-Biscuit. I don't have a valve on it - probably should install one this year - you're right it's a pain to keep switching.
Thanks again and have a good one.

either way on the heater core.
Valve should go in the intake to heater hose (limits the pressure in the heater core with the heater off)
