88 degree thermostat

Hey guys,

just wondering if anyone can tell me if one of these is the correct 'stat needed for the m50 conversions?

If so, which on? (The only difference is that i can see is that one has a gasket/seal and the other doesn't?)

Thanks in advance,
Phil

When I ordered my 88degree from sytner it came with a rubber seal. I would get that 1 mate cos there is no difference in the 2 what so ever apart from that. May aswel change the seal and stat in 1 go

So if im reading this right.....

the 88 degree thermostat needed for the M52,

is the stat out of a 2.5 M50 ?

if so,

why in the 2.8 is the thermostat a 92 degree one?
you would think that with it being a bigger capacity engine, BMW would allow it to run cooler not hotter

Good thinking but not quite there - extra capacity on the engine does mean extra cooling is required but that's done by the radiator. The stat opens at 92 on a lot of engines to get best fuel economy (at 93 degrees) whereas best power is actually made around 72 degrees. The size of the radiator dictates the final operating temperature - the stat helps with a quicker warm up...

If you are aiming for power, the best option is always the lowest temperature stat you can get your hands on - tropical or hot climate stats are always a good idea!
