Project Dumpster Fire is up to its old tricks again! Namely, I had just finished doing a cooling system flush and was ready to refill the system. I slapped in a new thermostat and gasket and began to refill the system. About halfway through I hear a hissing noise coming from around the thermostat.. Figuring it was the bleed nipple, I continued filling and filling.
Then coolant started gushing out of the thermostat housing.
I cleaned up the mating surfaces using a scouring pad and noticed some deep pitting in the housing, which is... worrying. Not sure what would cause that level of corrosion, but on this bright side it seems to be confined to the housing itself, which is a small part.
A smear of Permatex RTV and I re-mated the surfaces. We’ll know tonight if it worked.

Yeah I think the RTV will work just fine, as long as the pitting wasn’t too deep.

That generation used dexcool, right? If one of the previous owners mixed in something else, could have broken down the corrosion inhibitors.

There should be enough material to put it in a vise and file the surface a bit smoother. Remove some of the height difference between the pits and mating surface.

Nah. This Saab is from the 80s where green was king. This is probably just a consequence of sitting for 13 years.

Not a bad idea, but I don’t trust in my ability to not fuck that up. That’ll be my backup plan if the RTV doesn’t help.

If it comes to that, just put some sandpaper on a hard, flat surface and rub the housing against it to maintain a flat, even finish. Some thermostat housings have a small lip protruding from the mating surface to help “pinch” into the gasket, in which case sanding might not be such a good idea. But I don’t see that here.
