I've got to get some heat in this girl before winter time

I got the car with heater core bypassed and assume it leaks!

Some are saying the cheaper aluminum cores poop out quickly?

Some say you need to remove the dash-pad to get the heater box out easily?

I will remove the passenger seat and get the gasket kit for the box when the time comes etc.

what about a heater control valve?

What about a heater hose restrictor bung that stops the hammering of the core on start up?

Has anyone been through this?

Thanks

Paul

 
There has been previous discussion on changing a heater core in a 71 - 73 mustang with AC. Best method is to totally pull the dash (should take maybe 45 minutes if you take your time).

 
When I did mine I just loosened the dash bolts so that it would pull back easily and removed the heater/AC box. It looks complicated but was really simple to do. Good luck on the project. Be careful when removing the clips, those boxes are pretty brittle from the age.

 
When I installed my center console gauges I had all the screws out up under the

dash pad and the pad was loose in the front but when i tried to pull it toward me

and out it wouldn't budge?

Should I have yanked on it harder?

Are there clips on the windshield side that are super tight?

I read the other core posts but still have questions about

Copper vs aluminum

Thanks

There are actually 2 screws that need to be removed from the top of that assembly. The metal part of that assembly has 2 machine screws that are close to the windshield so you'll need a right angle Phillips screwdriver to remove it.

I would go with the copper core.

thx
