Need a diagram of fan belt routing fo a 1991 merceded, 190e, 2.6 engine

Go to the following link and the first photo shows the belt routing. I hope this helps as I know changing the belts on these vehicles can be a major pain in the neck.

Please do rate my response. Thanks!

2.6L - 103.940 engine, there is two belt routings, so here both, hope one helps you.

If it wont turn over try the neutral safety switch, if it wont start in neutral either the switch most likely needs to be replaced.

There are 2 PDF documents to open - above the photo on the site.

The first - the Routing Guide - shows the reference for the belt diagram (1987 MERC 190E) which is 6-2 on page 92 of the Guide.
The second PDF shows the belt diagram for 6-2.

Hope this helps.

Are you using the old belt or a new one? Just make sure the belt is the right one. There is only one right way to route the belt. There should be a diagram of the belt routing on the fan shroud or hood. If you can't find it, I've had some luck doing an internet search for the right routing diagram.

There could be 4, 5, or 6 pulleys on the 190E 2.6. Here they are.

Here is a picture, Good Luck http://www.2carpros.com/car_repair_information/tec_info/1991/mercedes-benz/190e/1991_mercedes-benz_190e_drive_belt_routing_diagram.htm
