Is the smell a problem. On my 996 like you I too noticed a different smell from my 3.2 (less oil and more coolant smell). I have changed the fluids, and established a baseline that i know is a good smell . I have continually cleaned the front radiators. Flushed the tranny again. Flush the coolant every oil change. The smell becomes less an issue once you know your gages are working well and the water temp needle is on the 8 for the most part, rarely on the 0 and at intense traffic temperatures holds at the 0.

It seemed like it was not long ago temps here were over 100 F every day.
