Spectra Premium $54.99

Curiously, when I tried to research Honda heater cores, I found a thread about replacing them in classic Mustangs--nothing said Mustang until I read a bit.

The consensus was that replacing heater cores is easy without air conditioning, but AC makes it terrible.

I don’t precisely remember how I found the OE supplier. I am almost positive it would have been from a message board. But now that I think about it, I imagine it’s a lot easier to find that kind of info on a maintenance item than on something like a heater core. I’ll poke around a bit.

EDIT: yup, harder than I had thought. I have found out that the radiator is a Denso unit, so I suspect the heater core might be as well. If that’s so, Denso no longer makes it.
