How much work is it to put in a new heater core in a 66 coupe, no a/c?

Dennis Beck

It's a fair amount of work. It's not hard work but the job is done in close spaces where it is hard to reach,see and use tools all at the same time. I think it would rank among the top 5 least favorite things to R&R on these C2's. If you take it on be sure you pressure test your repaired or new heater core BEFORE you put it back in. You only want to do this once. Enough said?

While not fun it's a whole lot easier than the newer ones that's for sure! It'll give you an opportunity to really know the passenger side of the dash and maybe make a few improvements (e.g. lube the wiper mechanicals, add/replace insulation, refinish glove compartment, change coolant, etc.) while you have things apart.

I sent you an e-mail through the forum with detailed step by step instructions.

Thanks everyone for your help. Pilman7 can you resend the directions, my email changed and I forgot to update my profile? Thanks again.

One tip to consider. The interior side housing has considerable latitude to move because of the size of the mounting holes in the firewall. It's position defines where the floor duct winds up, and therefore the console side panel fit. It can be a real PIA to get this right.

However, if you leave the foam gasket between the firewall and housing in place, the impression in the gasket will "index" the housing to the correct position when you put it back together.

I've done this job a couple of times. The only time I had trouble was when I decided to replace that gasket!

It's not a difficult job, otherwise, just takes a long time.

How long should it take for a heater core change in a 1963 convert when you have not done it before?????

Is this a one day job????

Yes. I did mine 2 years ago and it was easy. I needed my wife to assist holding the fan blower motor housing and get the first nut started. Remember, there is one nut on the far left side near the gas petal. I didn't think it was hard to do.
