I know many of you, like me, have a thermostat housing that seems to warp and leak just by looking at the damn thing. So I got on the horn with Charles over at MP and asked what he thought about making a plate that can be welded onto the housing to stiffen it up. He doesn't have a price yet, but I wanted to get some feelers out to gauge interest in a product like this.

Let me know what you guys think and who's in.

We've reached 35 units guys!! :cool:

Let's keep adding to this list! The more we make, the more likely we'll get them cheaper or have more made in the future!

PS: Charles would need a housing as a template, so if you have an extra one that can be used as a template, let us know!

I probably have 1 or 2 spares lying around. I'll look around tonite for them.

I would be worried about it warping with the heat of welding.

Ryan,

Thanks! Hopefully this will get enough support so we can get these made.

I don't see that being a problem if the person doing the welding isn't a complete noob. Exhaust pipes are a lot thinner than 1/4" steel too. Besides, Ricardo had one made and it's working well.

Charles said he needs about 30 people involved to make this work, so come on folks. You know you need one! :D

we definitely need more people interested in this. Come on guys, you know you want one of these to put on your housing for the next time you change your thermostat. :)

Chances are whoever you are going to get to weld the plate without warping or creating a pinhole leak will be able to make the plate for you as well. Exhaust welds leak all the time. Maybe you can get charles to do an exchange type of setup.

If it was that easy or that cheap, i would already have had one made. All the machine shops I spoke quoted a starting price of around $150 for a one off piece like this, if they even had time to make it. Most of that cost is in creating a program for the mill. That's why I contacted Charles about a group buy. New housings aren't available, and even if they were they would still be prone to warping due to the thin metal used. This should readily solve the problem. As for leaking, a welder with any skill shouldn't have a problem.

i've been without internet for the part few days, but I spoke with Charles and he's saying the part would be about $20 if we had 30 people involved. I'd say with fudge factor, the most it would be is about $30.

These plates should not require any milling. These should be able to be just laser cut then tig welded on.

You need to mill out the space where the T stat sits.

Dont mean to jump in but this kind of stuff is what I do. I run a job shop up here and have made one just like pictured. The only difference is I blanchard ground the mounting surface to make sure it was perfectly flat for mounting. I already have a similar milling program and can makle them if needed but if you want them cut and ground, I dont do grinding and they charged me and extra 20 bucks just for that. I will make the part complete for 45 if you can get an order of 25+ together. I would suggest .375 plate but I will make what ever you want. If you want them unground, 25 is a good price but I wouldnt suggest it.

Dont worry about the welding, any good welder can do it and it wont warp. I used a tig and didnt have a problem. Only ran it on a dyno do far for any hour or so but no leaks.

I only removed mine once to replace the thermostat (to 180 deg). Before I could reinstall, I belt sanded the gasket surface to get it flat, used a thicker gasket, and lots of sealant. IT STILL LEAKED.:mad:

A second resealing job and better torque, sealed the leak.:)

I may never remove it again, but you can never say never!!!:D

Yes, I would buy one of these new & improved housings, if the price was fair. Put me on your list and keep me in the loop.:D

Looks like 9-10 people are interested so far. Just to clarify, this isn't a new housing, but a plate that will need to be welded onto the existing housing. This should prevent the housing from warping and causing it to leak as the stock ones are prone to do.

In case anyone missed it, Charles expects it to cost $20 if we got 30 people involved. Worst case, $30 if the price of steel goes up.

Paul,

Steel prices can go up 200% and it wouldn't amount to more than a buck or two extra on such a small item :rolleyes:

I'm in for one at $20.

Waiting to hear back from Charles. Once I do, i'll let everyone know the final price, etc. The group buy is still open, so if you're interested and haven't signed up, it's time to get in. This is likely going to be a one time run.

Sorry guys, I have been kinda the hold up on this, getting Charles a stock housing for CAD design. Been busy trying to get my car back up and running along with the new Canton products. He said once he models up the piece, he will then send the CAD model picture to post here to see what everyone's opinion is. After we get a final general approval from the group here, he will then produce them.

YES I have an extra housing to send if you need it to work up the model?

Count me in too. Mine isn't leaking yet, but looking at the thing I can easily see how it would happen.

06-12-2010, 12:55 PM
Will these be TIG welded by Charles ?? Seems that MIG welding them at home might cause MORE warping with the penetration, and contamination cleaning. Plus a LEAK free seal, just to get it hot enough to get a bead flowing around and not have to Stitch the thing together makes for terrible welding. I just removed a leaking thermostat housing from a customer's car - it is warped and rusted very bad on the mating surface .. I dont believe it can be repaired without finishing it on a surface grinder afterwards ...

Currently this is only for the backing plate only. I won't speak for Charles on this, but you could ask him if it's possible to send him your housing and have him weld it for you.

I'm not expecting many people to weld this up at home. I'm taking mine to a local guy that does TIG welding. If it happens to warp when welding, I'll have him throw it on a belt sander or bench grinder and true it up. The added thickness should mean this is a one time procedure unless I drop it or do something similarly stupid to the housing. :p

And I wouldn't worry too much about leaking. A good welder can seal something like this up without a problem and not leave an ugly bead. And if I'm not mistaken, welds can always be ground smooth if you're going for a show quality appearance.

Exactly why I'm having these made. The stock housing doesn't seem like it was built to last.

So should I put you on the list for one (or a couple)? :cool:

I'm shipping a second housing to Charles for him to test welding a plate to. He seems to think that the stock housing will fall apart if welded on due to the burp tube being brazed on. In other words... he's going to test it.

As Damon pointed out Ricardo's already had a plate made and welded to his stock housing with no ill effects, so I don't see what the worry is.
