Thermostat Housing Help Needed

[Don Frelier]

You can hit the top with a grinder and then a flap disc on the upper portion and it will look way better.

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.

I have never heard of that. What is it?

It's a little brown bottle of non-hardening gasket cement. Has an applicator ball on the end of the cap. I've been using it for 50 years.

So basically use this in place of any RTV or anything like that?

Yes, it's what I use, been using for 50 years. What you use is your choice, others mention good stuff as well. I never had a leak on mine or any customers car ever. Of course, I ALWAYS ensured any surfaces were straight and true beforehand, how many mechanics have a straightedge in their tool box and USE it ?

Well, I'm more of a body man than a mechanic, but I'm also a perfectionist, so I do use a straight edge quite often, LOL.

When I was a kid working in a garage, I was going about changing a (water pump ? ) gasket. As I was, the older mechanic asked me what I was forgetting to do before my install. I had no idea. Says, "check the flat". Wut ? I'm not doing a tire, I think. He hands me his straightedge, says you never replace a part unless you know it's good enough to put in. He says why do all that if you don't even know if it will seal right ?

Those are great words of advice, especially today. I look over all my new parts to make sure they are good. You can't assume anything....

Personally, l like to use Permatex High Tak adhesive/sealant (brush on) on the hose ID. Although, i have used another Permatex profuct....windshield glass weather sealant....also known as "Gorilla snot"...its greenish gray....but remains pliable. I agree with the others....clean up your old t-stat housing and paint it....cast iron is rugged and durable.

I think you have received a lot of good advice already, but I'll tell you what I just did. My water pump looked almost as bad as your housing. I bought a new aluminum one, and mounted it. Then I figured out it wouldn't work with my AC brackets. I decided to remount the old pump. I cleaned with a wire wheel and then coated it with super "300". I used the "new" gaskets which I had removed twice already. So these gaskets, had been installed 3 times, days apart, and they still sealed perfectly the third time on a pitted old pump. It's great stuff and rated for antifreeze and non hardening. I just think back on how many times I used RTV when this stuff would have been 100x better.

Here is a nice flowsheet from Permatex on their gasket makers.

That's a great chart. All this advice helps because I have to do timing chain cover, water pump, intake, valve covers, and oil pan!

So we've quickly transitioned from a thermostat housing to a rebuild.
Next up.

Cams, stroker kits and headers.
Stay tuned.

Ha, no rebuild. Just a southern car that had every gasket possible leaking.

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

That's for A/C cars. Mine points towards the front of the car.
I ended up getting the old one fixed up.

Those are wrong. Pretty much couldn't find what I needed anywhere, but thanks. I buy most of my stuff from RA, so I had checked there, but nothing looks like what I needed. Checked Napa, O'Reilly's, Autozone, etc. It's just not out there.

A NOS thermostat housing would never be painted , I would expect a NOS one to be Bare. Please Correct me if i am wrong.
