Yes, my 400SE now runs up to 115 on a hot day with A/C on. But it never runs this hot when I bought the car new. The temp. gets hotter when the W140 was facelifted/new engine management(late 1994 as 1995 model).
Since you have 500E, it may have the same engine management as 500SEL. What if the car with DOHC V8s(pre-1994) are tuned with late-1994+ spec??? Is there difference in tuning?? Lee, and all alcknowdgable ppl, please tell me, thank you....
