I'm trying to remove the thermostat housing - the screws are out, but it's not going to budge. Any suggestions would be appreciated as I don't want to damage anything trying to get it off.
Also, after removing the impeller, discovered that 2 vanes had broken off. The hose between the water pump and thermostat housing was clean. Do I let this go, or should I be searching for them? Thanks

the thermostat housing is just stuck from the gasket. Carefully bang on it. Or sometimes you can use a putty knife to get under the gasket and that will give you some leverage on it.
The rubber for the impeller is probably in there somewhere. If you don't want to rip into it, then just keep your eye on the temp gage. A common place for pieces to show up is near the tranny oil cooler.

Those impellor pieces will get stuck in the exhaust manifolds and in the bypa$$ hose 90 degree fixture if you have one. They are also the perfect size to get stuck in water veins in the block. Use a little blue rtv to hold the gasket in place when you put the thermostat back in.

Thanks for the suggestion, I wasn't familiar with that, but I'll give it a try. The old gasket is a mess - any tips on cleaning the housing to prep for the new gasket?

Get one of those gla$$ scrapers that holds a razor blade.

Gasket remover makes the work easier too. Comes in a spray can, available at auto parts stores.

Yeah, that stuff works great on head gaskets, but never had to use it on a thermo gasket.

I use a wirebrush that goes in a drill motor, removes left over stuck on gasket but no metal from thermo housing or intake.

I usually use a gasket scraper. You really want to find those pieces. I would check the Tranny cooler and the hoses to the manifolds. It is possible that they will block a cooling loop and all of a sudden the manifold or block will get really hot. It could do some damage.
