Heater Core Question

Since the engine is out for a rebuild I'm going to replace the old heater core. It's a '78 F250 with a 400 and factory A\C but I'm removing the A\C stuff. What heater core should I put back in it, an A\C or non-A\C unit?

Does anybody need the A\C stuff I'm removing?

if its factory air you have a big box on the outer firewall. to go to non air it would leave a HUGE hole in your firewall. easiest route would be to remove evaporator and replace heater core with a factory air one reusing the big factory box. this also makes it easier if you ever decide to reinstall air

I just did the same thing. You will have to put the same type of core in as the other one has the tubes coming out to the side of the core.

I agree; it's easiest to just keep the factory AC box in place, in which case you'd use a heater core for an AC application (which has the tubes oriented in a different fashion as Kevin explained).

It is possible to get all of the heating stuff from a non A/C truck and cover the hole in the firewall if you really want to get rid of the big box.

Alright, I'll leave the box in place and go with a factory A\C heater core.

Thanks!

It's almost Summer, what do you need heat for?

J/K... I would swap over a non-a/c unit and cover the hole with sheetmetal.
