Thermostat Housing Prestone Nipple Connector

[88Sedan]

Forum search and google search on this didn't come up with much...

I want to refasten the press-in nipple on my thermostat housing. The housing is in good shape and is original BMW. From the looks of it, BMW changed this connection later on to some sort of a straight nipple press in connector, mine is the older 90 degree press in style.

What's recommended here? The fit is very tight, not leaving much area for sealant. Right now I already cleaned it up and resecured it using coolant safe rtv. I really don't want to spring a leak later and have to take everything back apart again.

Since this is a pressurized and hot part of system, I feel like something more strong than sealant might be a good idea to hold up against the pressure. Everything I've read says JB Weld isn't coolant safe.

I would recommend replacing it with a new OEM housing.

Hey y'all, do you know what the part number of the nipple is? I just removed my thermostat housing due to the nipple corroding and eventually shearing off with a wiggle of the hose.

Due to the nipple being a press fit, would y'all recommend trying to bore out the hole and press fit another or just buy a new housing?
