Serpentine belt change
Was looking around under the hood of the 320 the other day and noticed some cracks in the grooves of the drive belt. Got a new one and put it on yesterday, with the help if the belt routing diagram in the owners manual. I don't think it had ever been changed in 140K, but I was definately running on borrowed time. I could split the belt apart in my hands. It is just something you don't want to have to do out on the road somewhere, so take a good look at yours if the miles are getting high.

Good advice, Pete. I did both my cars a couple of weeks ago too. It's amazing just how easy they are to change too!

They ARE easy to replace!
I've done mine three times during my ownership. Sometimes you don't even see the wear until you take the belt off and inspect it. I had one belt that had a chipped groove, and when it went around the smog pulley, it sounded like a worn clutch bearing! Again, couldn't see the damage on the belt until I pulled it...

How involved is the belt change on a 112/113 engine? I've done plenty on a 103 but these look a little bit more complicated.

Paul, just make sure you have a routing diagram handy and it will be a snap. I just did it on an M119 (which has a similar routing pattern) and it took less than 5 minutes. It's actually a lot easier to do than it looks.

The 104 was a bit tricky without the fan blade off. Routing the new belt over the main crank pulley had me twisting my tongue a few times for sure. Of course the 2 piece fan shroud comes off first. The routing diagram is invaluable.

Serpentine Belt Change - 1991 190E
Can anyone help with this? I've seen that it's fairly easy, but I don't wanna do anything incorrectly or out of order. Any quite but concise instructions?
