M104 Serp. Belt
Hey I am doing my 100,000 mile service. Change Oil, Tranny Fluid, and Diff. Fluid. I am next to change the fan belt. The Mercedes Bible is very vague on the process. I have the shroud off but I Can't see anything they are talking about.
Thanks
Brian

I've only done a belt on an m104 once on a 1992 300Ce, and it was a Pain... You are supposed to remove the viscous coupling. I managed to do it without removing it.
It was very hard to get the belt on, after some heavy fiddling I managed to do it, but only with the help of a friend. My friends belt broke on him while he was driving, and he managed to make it into a gas station. We worked at it for probably about 2 hours and finally got it.
My recommendation would be to have a mechanic do the belt, unless you are willing to try to tackle it yourself. routing it is not bad, but getting the tensioner loose enough to get it up and over is not. you need a tool to pretty much lever the belt up and onto one of the pulleys to finish it up before retightening the tensioner. you also have to be carefule to not overtightent he tensioner as you can break it if you over tighten it.
