robmack indicates in post 47 that it's not a good fit. Perhaps we need a confirmation.

If anyone has bought a gasket that fits or doesn't fit, please indicate the complete maker and part number.

Regards

BMW OEM - perfect fit (manufacturer & part no. TBD)
ttg26 - fits when used with Tridon High Flow Thermostat TT2014-180
ttg47 - not a good fit (too large)
ROL Gasket WO8285-001 - does not fit

Reinz 225 33099 071 - does not fit - too large, 60mm diameter

the gasket does the job well

the new thermostat has solved my recent and not so recent (over the last 3 years and 2 different radiators and 2 stock thermostats ) heating issues big time .

not even idling for over 20 minutes in traffic jam moderately hot day ....in the mid thirtys (c) at least ...(after a quick run of over 150 kilometres ...so it was well heated and up to temp )....could convince the system that it even came close to turning the fan on.
or even indicating much over 92 degrees .,,,,at any part of a 600k (round about) trip over hill, spirited mountain climb and dale

thoroughly recommend the process ...

ill detail it somewhere else

Which gasket?

Is the new thermostat original BMW or substitution?

Please provide details.

the substitution ttg26 gasket and the high flow Toyota thermostat as mentioned earlier

I have some other findings though ,,,, as said, ill post the results ....when I can get pics up from the phone .

Just to make it clear for everyone, so they can source this gasket if need be:

ttg26 is Tridon Thermostat Gasket TTG26

This gasket fits when used with Tridon High Flow Thermostat TT2014-180.

The TTG26 looks as though it has a longer rectangular cross section than the BMW OE u-seal and may not fit on the BMW OE thermostat.

I think we are still looking for an aftermarket thermostat u-seal that fit the BMW OE thermostat.

Regards

I took delivery of the eBay gasket today and I'm sad to report that it does not fit.

The ID of the eBay gasket is ~60mm while the OD of the thermostat is 47mm, according to my caliper. TTG26 appears to have the correct ID and OD measurements.  Unsure about thickness though.

What's the resolution of your caliper?

If you can take some accurate measurements to the nearest 0.1 or 0.01 of a mm, then please check the dimensions of the thermostat housing inside diameter and the thermostat flange diameter that mounts the u-seal as well as the thickness of the flange where the u-seal mounts.

I contacted Max BMW parts to see if they could source this u-seal like Motorworks does. They are looking into it, but requested some dimensions, because they don't have a thermostat in stock.

Regards

Old topic but same problem as before. My thermostat gasket was broken after thermostat pull off. I asked Motorworks but they don't have this gasket on the stock anymore. Do You have any idea where to get one?

O-ring is fine and I mean this 2nd gasket..

Seems to be expensive to buy a new thermostat just for a new gasket!

EDIT: Per post #56, this gasket/seal does not fit. Disregard this recommendation!

Check out the part below. I suspect it may fit per previous posts on this thread. The part description indicates that it interchanges with part number 225 33099 071. However, we need a good confirmation that it fits. It only cost $1.44 shipping not included. If shipping is reasonable, I'd give this gasket a shot.

If shipping from Mercedesparts.com is too expensive, you might be able to find this Reinz 6012030076 seal locally in Finland. Good Luck!

See posts #16 through #19 on this thread.

I was thinking the same thing after I reread the thread and saw post #56.

It's been a long time since I was investigating this issue.

I think there must be a suitable seal available, but someone has got to find it and post the information so others can benefit.
