I put a 190 stat in my cummins engine, and it holds that perfectly down the road. If the ambient temps are below 30 it takes a half hour of driving to get it there
This is with no cooling fan whatsoever. Everything about the engine is cool, the EGTs are also about half what the TDI's are running.
The beetle TDI's will get up to temp in the same conditions in about 10 minutes.
