Fox body heater core

[USAWIT2]

Heater core starting leaking in my 91 last summer so I just bypassed it. Missed it on those cooler days in the fall so figured it was time to replace it.
Doesn't look like OEM ones are available.
Just wondering what brand people are using? Any brands to stay away from or are they all about the same?
Prefer not to have to do it again in a year.

Seen little to no difference brand to brand (beyond OE of course).

I replaced mine in 2006 with one from the Ford dealer.
Made by Valeo.Same company that supplied Ford with clutches.
Sucks if they are no longer available.

It is better built than the previous NAPA heater core which lasted 8 years.

Well hoping the one I ordered lasts for a few years.

Also are these flow restrictors necessary?

I have to check my hoses to see if they had one from the factory.

I ordered new hoses so maybe they will have them?

Not a bad idea.

There was usually a restrictor in one side on the factory hoses, and the Ford OEM replacements when available had them too ... so the engineers must have felt they were needed.

The problem was too much flow at higher rpm through the core. I put a socket in one of mine so it would restrict the flow and I couldn’t wait for the actual restrictor

Well the new Gates hoses I purchased didn't have the restrictor, end up using a 3/4 pex plug and drilled a hole thru it.

Heater core is back in, cars back together, no leaks hopefully it stays that way for a while

^ Nicely done.

Hi there,

I had ordered my heater core along with the hoses through mustang depot here in Canada, and on of the the heater hoses included the restrictor in it. The part # 3943047.

I wanted to ask you, do you have any tips that would be easier to replace the heater core, as I will be doing mine in the spring myslef? Were you able to put the dash back up yourself or you need to have another hand?
