Thermostat Housing Help Needed

[Piranhaz]

So I have a 66 Coronet with 318 Poly. This car had been sitting for awhile so I am going through the engine and replacing most of the gaskets (a lot of oil and water leaks). So I took my thermostat housing off and it's pretty corroded. Figured I'd just go on-line and buy a new one........... I can't seem to find any place that has the correct one. I find a bunch of the ones for A/C cars, but none like the one that I have, that is non A/C. Does anyone know of another part that will fit or will I need to hunt down an original? I attached a picture of what mine looks like. TIA.

From what I see blast it , sand the gasket flange till flat and paint it.

The inside where the thermostat was is the worst. I am gonna try and clean it up, but it's in tough shape.

Your call. Unless severely eroded you can still make it work

Might have to. I can't find anything anywhere. I'll clean it up tomorrow and see how it looks. Thanks

Had to replace one like that last summer, put an WTB ad for what you need, that’s what I did.

Yeah unless it has holes in it, I'd run it.

That's it. $80!! Says NOS but appears used? I'll try and get my cleaned up tomorrow and see what it looks like. At least I have an option now. I searched eBay too and that never showed up, weird.

That's an easy restorable t-stat housing.

That’s a crazy price. I would use that part number if it looks right and search auto part stores.

I'm glad to hear everyone saying that. I'll give it a good cleaning and post some pics tomorrow.

I would clean it up too, yours doesn’t look that bad.

It's high because it's the same one used on a 66 Hemi car.

It's also cast iron, sort of hard to destroy. I know it was used on a lot of engines thru 66

Well that makes sense now why they are so expensive.

Well, the neck looks kinda crusty but I think the hose will seal at the bottom. Should I use anything else aside from the thermostat housing gasket when installing? A little RTV maybe to fill the rust gaps, or will it seal up without it?

Tape a piece of 80 grit emery paper to a flat surface (I use an old pane of glass), and sand in circles till you get a uniform surface. Then, whichever sealer you like with the gasket. I use permatex 2. Wire brush and paint the rest. Rtv inside the hose end.
Worked on my 90 year old housing that looked worse than yours.

Wipe the inside of the hose with Indian Head before you slip it over the neck. Also apply it to each side on the gasket surfaces.

Sounds good. I was wondering about the hose end if I should put a smear of RTV around the neck before installing the hose. Thanks
