T-stat housing gasket

So im planning on doing a cooling system overhaul this weekend and had a revelation... the kit i got had an aluminum t-stat housing with a gasket in the roughly rectangular part but there was no gasket around the circular part that covers the t-stat itself. is this normal? do i not need a gasket? or should i go to the dealer tomorrow and try and pick one up?

To be clear the kit DID include this gasket

but did NOT include a gasket that looks like this

BTW i have the M52 engine.

That housing gasket is very weird (the one not included). It doesn't fit flush when the t-stat o-ring is in. So I haven't used it for the last two t-stat housing replacements I've done. No leaks whatsoever. I guess it's not necessary.

You do not need the second gasket you linked to. That was for an earlier design. The "rectangular" gasket and the large o-ring which comes with the t-stat are all you need. I'd also recommend dabbing a little 02 sensor save t-stat RTV sealant around the "rectangular" gasket. Just barely enough to get a little bit of squeeze out (but just a tad).

Ah, that's it. It's for the non-vanos engines. Makes sense since it was in the non-vanos headgasket kit that I got.

Yeah, I have vanos. I'm saying that the paper housing gasket is for non-vanos engines. That's why you don't need it.
