I had all those 123, 124 and 126 benzes but this is new field for me...too many questions already. Have to figure out:
1. where to get excellent service manual
2. egr delete ?
3. ordered new cooling fan clutch, but looking at old one, cant see how to remove it ! another mercedes special tool?
4.transmission dipstick?
5.....
I think great service manual will answer a lot...not all..thats why we have forums....
Thanks for sharing your knowledge...
Aloha.
