Review on High-Quality Water Hose Fitting Replacement for BMW 335i N54 N53 N52 Engines - 11537541992 11537544638 by Robin Naber

The supplied o-ring is too large. This is after I spent the better part of an hour and a half getting the flange back into place. I tried to fix it with screws but it didn't work. I almost thought the flange itself wouldn't fit, but it does fit without the o-ring. It's a terrible place because if the flange didn't fail before it probably took it off, which is what happened in my case. Now I have one flange that doesn't work and one flange that broke. I just gave away a rein flange that I ordered for more than double the price because I really don't want to play the game of trying to figure out which one comes with a working o-ring. Now my car is standing still until tomorrow.
