Heater box questions
1) Does the factory under hood A/C box have to come off to replace the heater core on a 68?
2) Will a NON A/C box and heater core work on a factory A/C cab? I just got the truck and I want to drive it, but I need heat. I will be upgrading to a Vintage Air or similar system in the future. I have a stock heater box laying around that I would like to put on in the meantime to have heat. Will it work?

Re: Heater box questions
I have recently replaced mine on 72 C10 w/factory ac. Heater core is located on cab side firewall below and behind glove box. Housing has 6 bolts total. 2 are removed from inside and housing has 4 studs fixed that go thru firewall and has nuts on engine side firewall. The four nuts on engine side are tricky to locate and get off. Factory ac and non factory ac are mounted differently and are different size.

Re: Heater box questions
If you have factory ac, right fender/fender well does not have to be removed. Heater core and housing is removed from cab side. . Without factory ac, yes you do and also right hood hinge. You can remove the rear bolts of hood hinge, leave and loosen front bolt, tilt hood and hinge towards front then tighten front bolt hopefully without completely removing hinge/hood. (Things you have to think of when you are working by yourself!!!) Blower motor is located behind hood hinge too.

Re: Heater box questions
so with factory ac to remove both I will have to do the hood hinge trick to remove the evap/blower and get the heater from the inside
Heater core is in its own housing under and behind glove box which is removed from cab side. (W/Factory AC) If heater blower motor needs to be removed, then the right hood hinge will need to be done, which is removed from engine side. Motor can be removed, if needed, with approximately 6 screws. Last edited by Bandit130; 02-26-2015 at 05:18 PM. |
