Any ideas as to what I can do to hold the tensioner in place? I don't have another person to help, and I cannot manage to hold the tension down as far as I need to get the newer, slightly smaller belt on. It's pissing me off, something so simple and I can't accomplish. This is has been going on for a day now.

And I have been trying to use things as a wedge to hold the the cheater bar I have on my on wrench.
I don't like how there isn't a slot for a drift like there is for the supercharger belt. Great logic, let's design a lock mechanism on the most accessible pulley on the vehicle but not one on the bottom of the engine. Brilliant! The engineers must have went to community college.

Disregard. I made an extra hand to hold the tensioner while I could use both hands to force the belt into place.. It's running fine now, now on to cleaning this engine bay...

Is your cheater bar angled or something? I only ask because the accessory tensioner is further to the right.
Also, I hope that s/c belt is being replaced!

No that's a bar resting on top of the actual cheater bar lol, almost like an elbow except it's not welded so it's EXTREMELY iffy...I had to be really quick and careful because one wrong move and everything is spring loaded so it'll slip right off...
I'm glad I got it on, and yes! s/c belt is replaced. I think I'm going to replace the s/c tensioner pulley bearing soon, it's has a slight squeal to it occasionally

Get one. You'll never have this issue with the belt again.
I also have one of these sets, but it's too shallow for use on the accessory tensioner.

Belt Diagram
Super DIY here is a picture of the belts
picture one SC Belt Purple
Serpentine belt black
Picture 2 SP Belt Red sry did the drawing on my mobile with my little Finger
this helped me a lot the feeling it back took me approx 15 min from up and down W splitted IC TANK mounted even less room was easy but trying to guess your way DON'T just print and use this
start bottom always and finish At the top I always do generator last
START Feed it back over
4 AC Compressor and over 3 Power Steering pump
2: continue over 5 Crank and around 2 belt tensioner - 6 coolant pump.
8 back to top over idler pulley and put on your 17mm pull back and feed it over Generator/Alternator is tight yes is a new belt )
Clean up with Wurth Brake cleaner and dobbelt check belt sits properly on all pulleys, fire up the beast!

I noticed you still have the OEM idlers on your car. You may want to upgrade to billet idlers as the OEM bearings fail all the time, and at the worst time. The Gates HD green belt is also a nice upgrade for the supercharger belt. Nice write up and good details.

I worked on this today and I want to add this tip:
I had access to it from below (car on jack stands and the tray removed), but it was much much easier to do it like I mention above.
- Remove the fan shroud. Everything gets easier with it out of the way.
- I used a long 17mm attached to a torque wrench that I use for wheels.
- The lower tensioner (for the serpentine belt) very easy to do from the top with the left hand holding the bar pressing the tensioner open and the right hand slipping the belt over. VERY EASY.
- A breaker bar will work just as well, but this is nice because you can ratchet it up nice and close before starting the push to press the spring in the tensioner.

I apologize for bringing up this old thread. I had a similar issue with my vehicle recently; I had a visible crack in my serpentine belt. I get a proper tool for the DIY then follow certain procedure on how to replace it. I came across an in-depth article that may be worth reading. Search for "Mercedes-Benz Serpentine Belt Replacement Guide on YOUCANIC" and you will see an article that goes over common causes and possible fixes. You can read about it yourself. I hope this information can assist someone else with a similar issue.
