My 240D had always been right around 98-102 since I got it a couple of months ago. The bottom hose going from radiator to thermostat was always much cooler than the upper. Well, I changed the thermostat today, and now the temp stays around 82 to 90 at the most.

Side note:
My old thermostat had "92" or "94" written on it, but my new one, "80." So did the PO put in the wrong thermostat? Or perhaps, as someone mentioned in another thread, the "94" refers to the full open temp, and "80" on the new one refers to the 1/2 open or partial open temp?


The valve adjustment a couple of days ago and now this. What a great feeling. Thanks to this forum and its archives.

Now if only I could figure out the bouncing (see my other "non-TD bounce" thread).

92-94c is way too high for OM-616, in India, they get 79C for normally aspirated and 72C for turbo, with that they never run higher than 90C even in extreme conditions, however, take away the muffler on the turbo and do a ram air mod, they run at 80C steady, day in day out even in 50C weather, you also get improved mpg, the muffler removal can only be done on the turbo as the noise gain is not significant as compared to the normally aspirated one.

Wow! (for the low temps)

Wow! (for the 616 turbo) I didn't know such a beast exists.

Yep, the 616 turbo was always there, MB made it for commercial purposes but never put it on the 240D, would have been nice if they did.
