I just did my 1995 E300 diesel today. Took me 45 minutes using your wonderful article. After reading and looking at the pics I knew what to do. I used a hex key and a cheater pipe to remove and replace the hex bolt. Didn't torque it but its real snug! I used a small c clamp on the water pump and belt combination to secure it to loosen and tighten the 8mm hex bolt. Worked very nicely and cost 1.99 at Harbor freight.

You have a flair for techical writing and technical photos. I am in your debt.
