I’m not getting any heat in my car and I feel I need to replace my heater core. I’ve done other procedures but still not getting any heat. Is there a guide for the replacement of it? Thanks

Not a fun job. The basics are that you have to recover the AC charge if it has AC, drain the coolant, then remove the instrument panel and the heater unit. Take the heater apart and change the core and reverse the process. Book time in a fully equipped shop with experience in them is eight hours.

There are a few places that have the factory instructions Mitchell, Alldata and there are even full copies of the factory manuals online from back when Honda had them for free. Honda hookup is one such place, in their downloads area.
