If you take the bottom bolts out of the alternator its will shift about an inch which should give you enough space to take the belt off. Then put the new belt on and have a friend pull the alternator so the holes line up and put the bolts back in. You can also loosen the automatic belt tensioner which will also give you more "play" to remove and install the new belt.
OR
First step is to loosen the tensioner. Loosen the center 17mm bolt first, and then loosen the tensioner adjuster, but be aware that these threads are backwards. This will loosen the belt enough to get it off.
Then, put the new belt on. But if the tensioner is old, be prepared to purchase a new one if you can't get it tightened to the mark on the tensioner. These tensioners get old and lose their springiness inside, and the only visible difference will be the position of the center part. It will be pointing in a different direction. Change the pulley at the same time, as these bearings don't last forever.
Make sure you have the two special tools required to remove the fan. The job will be much easier with the fan removed. One you can make from a stiff wire, and this holds the fan in place with the pulley via two holes that align. The other tool is a very short Allen socket which fits into the center of the fan.
Good luck

For a 190E 1984 Model, it is about 60Litres, this is 13 Gallons(UK) or 16 Gallons(US). For a 190E 1993 Model it should be the same +/- 5Litres.
If it's serpentine, you have spring loaded idlers, you just pry. If not, loosen bolt on one of the accessory brackets with an adjustment slot (like alternator), then can move inboard.
Loosen the tensioning pulley and install new belt. There should be a routing diagram in engine compartment or on hood.
There is no filter:)

my 1993 190E 2.3 is doing the same thing. just replace the switches...they tend to not last
You will first need to loosen the serpentine belt in order to remove it from the drive pulley. After that, it is bolted to the engine in 2 locations, which should be rather obvious, then remove electrical connections.
Looks like you have to loosen the tension on the serpentine belt first. Only one bolt is not easily accessed. If you don't loosen the belt, you have to hold the belt out the way (with tension on it) and try to get the bolt in and hold the housing up at the same time (good luck with that unless you have three hands), it can be done though. I am not much of a mechanic and it took me about 1.5 hours with the serpentine belt in place.
