Title: Heater core help
Post by: Matt13 on March 23, 2020, 02:59:08 PM
So, my 1973 Barracuda came with no hoses on the heater core and a bypass hose rerouting the flow. I've got to assume the core is bad. Is this a difficult job? Any tips?

Tip #1 Plan to remove the entire heater box and replace core on the bench.
Tip #2 Get a new core, don't try and mess around patching your old one
Tip #3 Get a new rebuild gasket kit from DMT while you're at it.

Tip#4, check heater motor before taking out so you can pre-order a switch or motor before hand if needed.  :D

And don't forget there is a hook on the right side near the dash.  :alan2cents:

Awesome. Thanks guys. Luckily the blower motor works, so hopefully it's just the core.

 The "foam" seals in all the doors, inside the heater box If original; Have turned to dust..

Have they been remanufactured?

Yes, there's a kit you can buy. Heater box rebuild kit.  Try Roseville moparts.
Also, as far as heater cores go, I would recommend staying away from the aluminum ones.  They dont fit well.  I wound up returning mine and ordering one from rockauto.

Ok, thanks. Year One also has cores. Wondering if I should try theirs since I'll probably be ordering some other stuff from them.

Tip #5:   Take LOTS of pictures, especially of the vacuum hoses including how they're routed around the box and where thy are connected.  Note where there is a stripe on the hose and the color of the stripe.

There's only vacuum hoses if the car has air conditioning  :alan2cents: otherwise it's pretty straight forward.

YearOne is sometimes a good one stop shop, but they don't always sell the best quality parts at the best prices. Reach out to Roseville Moparts for the best around service and mention you're a member here for a discount :twothumbsup:

I don't mean for this to sound like a sales pitch, just giving good advice....  No matter what part you need, contact Roseville first before going somewhere else. You don't have to worry about fit or quality. You talk to people that know wtf their doing, not some flunky hired to answer the phone.
