  • Geniune BMW Thermostat Housing WARNING - 2020

    BMW has changed manufacturers of the composite thermostat housing and that manufacturer is providing a "red" silicone gasket (there is also an orange version with the same oversized dimensions). DO NOT USE this gasket. These gaskets are oversized and will cause the housing to crack during installation or deform the mating the surface. These are the same gaskets that all the metal housings come with, do not use those either.

    You need to order an original style Elring gasket. They are orange and have a pointy tapered tip on both mating sides. It's possible BMW still sells the proper gasket when ordered separate.

    Toodaloo provided this pic of both. The "red" silicone gasket is installed and was included in the Genuine BMW thermostat housing box. The orange gasket on top is the original specification gasket that is known to work.

    good catch. isn't elring the oem supplier though so won't their versions be the same as the "genuine" piece?

        No, look at the pic and what I wrote.

          This really is bad business. Quality control seems non-existant these days in the E36 parts department. I'll make sure to keep my currently installed gasket, as long as it's not broken on my (2009) replacement composite housing.

          Althoug looking at the old pic I took in 2009, it looks more like the red than the orange gasket. I would have to find the original size pic to confirm.



          Selling a housing with a gasket that makes it crack is just beyond comprehension.

              Can confirm - This explains a lot. Mine cracked during install.

                This is the Elring from ECS using the BMW part number to search for it.
                https://www.ecstuning.com/b-elring-p...531740437~elr/

                It states that it is for the new aluminum housing. Is this correct for the original plastic housing?

                      This is the kind of information I love to see on forums: timely, informed, well-researched technical knowledge. Thanks, Brett.
