Hey Guys, I have a dead heater core sadly, and I am trying to find out if the model for the 1981 FB's is the same as the pic below. My heater core lines coming out of Firewall, are straight out. Where as the one in the pictures shows 90 degree bends on the ends.

Thanks,

If its the same setup as my 85 SE, which I would assume so, the lines going through the firewall are not the heater core itself. The heater core has 90 degree lines coming out of the hosing that connect to rubber lines that go back to copper to wrap around the housing and go through the firewall. When I got my 7 I thought the heater core was busted, but after taking it apart I learned the external lines were busted and they are not that easy to find. So when you do this job, be very careful with the lines.

 

Hey Thank you for the quick reply!
I will be doing that soon.

 

try napa or rockauto or do as said and take old one out and rebuild it an put back in.
