people has talked about earlier about the pulley that will not fit on a 03 c230 sedan, is it true ?

 

The pulley kits made for the 2.3L won't fit the 1.8L and as far as I know there are no kits available for the current 1.8L. You may see kits for the older european 1.8L but it's not the same.

 

I was sure that this current crop of 1.8 Kompressor motors (badged C180K, C200K and C230k) were the first by Mercedes with that engine capacity. C180's previously were 2L naturally aspirated cars and the smallest Kompressor engine was a 2L Kompressor (badged as C200K) until they produced the M271.

Cheers,
Jim.
