Talking Heater core box on the fire wall side ?

I have searched for this Question but know luck.. Would it be safe to say that the Quarter panel would have to come off in order to get the housing off the fire wall ? there appears to be 1 or 2 more nuts or bolts that you just cant get to . this is on a 67 camaro .

Re: Heater core box on the fire wall side ?

If you're changing the heater core, the engine side does not have to come off.
Remove the six nuts shown on the engine side, remove glovebox, and pry off the box inside after removing coolant. Lay down one piece of plastic to cover from the trans tunnel to top of toeboard to seat to over the rocker panel to collect remaining coolant from core.

Cables don't have be disconnected either. Use 5/16 inch socket to remove clip and pull out core. Compare size of replacement to OE core if still there. Some here have said new cores are of thinner design. If you can, have OE core repaired and replace in reverse order.

You can use clay weatherstripping to reseal the core box back against the firewall.
Instructions are for a non-A/C heater - I haven't done one of them.

A search will uncover the conversion process and which cores fit what. Origional BB heater boxes were indeed different dimensonallly but the conversions do not require an origional BB box. Pressure test the heater core prior to installation, others have found some to leak after all the work.

Re: Heater core box on the fire wall side ?

Changing because you're changing to a BBC engine? If so, you can flip the core to make the outlets move to the center, then drill holes for the outlets and block the old holes. I have a smallblock heater box and core in the normal position with my BBC 427, and never had any clearance issues with it.
Not sure why everyone is changing them, unless they just want that OEM look.
