OM603coolant leak just near turbo

Found coolant leak on pass side near turbo. there is water pump in the front, and just rear of pump, some kind housing with hose goes in, I guess it's thermostat housing. It looks like has two parts, one part mount to the engine side, and before that another one and it's leaking. I can't find any gasket for this part. Any ideas?

Thanks

That's 100% the thermostat housing.

OM603 T-stat change


I would clean everything and recheck to be sure.

Don't forget to grease the screw and threads on the spring compressor.

The gasket should come with the thermostat. It's just a rubber thing that looks like an O-ring.

One member states replacing it is very easy.

Unfortunately , it's not a thermostat seal, it's whole bracket seal.

Anyone have do without lifting a car? Also looking for p/n for the bracket seal.

Help will be nice Thanks

Assuming you're talking about Part #315 in the drawing? The document you linked is the instructions to R&R that part. The forum sponsor has the gasket here: https://www.pelicanparts.com/More_Info/6062010180.htm?pn=606-201-01-80-M17&SVSVSI=3342#
