Thermostat housing leak after thermostat change; Not sure if I got the right part.

I changed my thermostat because I needed to change the top radiator hose and they were close together. The first one from O'Reilly had a gasket that was way too thin and I took it back. They also ordered a hose for me and it didn't fit either. They couldn't find a different gasket that would work.

The second one I got at Napa and it looked the same and fit but it wasn't a really tight fit or anything. when I put it all together I have a pretty steady leak from the housing.

Is there a special gasket for 95 metros? Does the housing warp or do strange thing that make it need to be replaced?

Had the exact same problem 2 months ago. Pulled it back off, sanded both surfaces of the housing & made my own gasket from gasket sheet material I keep on hand. It's thicker & seals better. You can staple or wrap a sheet of sandpaper around a block of wood to sand the housing if it seems warped. Makes for a nice, flat, surface.

A slight smear of indian head on both sides of the gasket before installation and your leak troubles will fad away. Make sure your thermostat is seated correctly and be careful not to break your thermostat housing. Often people will leave a tiny part of the gasket left on one of the surfaces and that small piece of gasket will cause it not to seal well. Always clean both mating surfaces well being sure to remove all the old gasket. The improved gasket is better but either gasket should work. Take a look.

On cars and boilers.. if the surfaces are not perfectly flat and clean they leak unless you cheat with some glue or silicone... I've used gaskets from Napa and from Amazon and had no problems...

I highly recommend the Dodge Neon thermostat seal. It's fat and beefy and provides a much better seal than stock.

As originally suggested by BadBent:

"If you find any water or moisture, go to Autozone (or similar) and ask for Fel Pro part # 35588. (Federal Mogul). [1.615" ID/1.989" OD - .25" thick ] Place thermostat in the seal. (Seal's inner diameter is slightly over-sized on the thermostat, but it works just fine.) Then equally compress the two housing bolts till sealed."

Technically Bad Bent did not write that, it was copied and pasted from here.

Probably worth giving the original author credit.

Not all thermostats use a seal around the thermostat. I do not think his 95 does. I would not recommend trying it on those not designed for a seal around the thermostat but only a gasket. Actually I believe the seal around the thermostat is designed to prevent coolant from bypassing the closed thermostat. It is to help seal the thermostat to be water tight. It is not designed to seal coolant from leaking between the thermostat housing connection. This is the function of the gasket.

I also took my old one in. Parts house hunted around for it then gave me an identical one.

So, if I were to use the neon gasket, would I use a metro t-stat with it or use a neon t-stat? Or will both work?

I have a feeling, both would work... but I used a metro t-stat with a Neon gasket.

use the neon gasket on a metro thermostat and make sure the weep hole is in the down position.

Perhaps you should look harder.
