Hi,
Newbie here, but saw this picture of drivers side 996 “engine” and was wondering what this is (circled in red in picture.)

There seems to be some “paste” on a side and was curious if this is normal.

I don’t have a better photo at this time, but any help is welcome.

thanks!!

Water pump?

That is the thermostat housing.

Thanks!
