Starting from the crankshaft inner pulley, the larger belt goes counterclockwise to the upper mechanical tensioner, then to the water pump, upside down to the idler roller, and then right-side up to the alternator pulley, and down to the power steering pump pulley at bottom right, and then back to the inner crankshaft pulley at bottom center.
The outer belt goes from the outer crankshaft pulley at bottom center counterclockwise upside down to the lower mechanical tensioner rightside up to the air conditioning compressor and then back to the outer crankshaft pulley.
Part at left is just a grounding block, or a nice way to ground a lot of wires as far as I know. Note all the wires going to it are brown. Brown = chassis ground.
The circled part on the right is the expansion tank bleeder screw.
You've helped a lot on this thread; and I appreciate your efforts!
that looks like a starter solenoid with the larger round case below the actual starter motor.[/quote]
Ah, I see what you mean. Thanks for the update. The hope is that we can identify ALL the 'objects' in the E39 M54 engine bay.
This is not only for me; but also for anyone asking where a certain part is. The hope is that this one thread contains pointers to everything visible, so that we can just point 'em to this thread to learn about their engines.

It's located behind the reservoir for the power steering and under the intake manifold--one hose coming in and one going out--there will also be an electrical hook up on it--when I had this code come up I cleared it by tightening the gas cap on the car and that worked for awhile--then I removed the rubber 0 ring on the gas cap and on the 0 ring there on the outer edge of it I filled that area with black Permatex gasket maker and let it sit up overnight. By doing this -it made a tighter seal around the cap.. Year later my purge valve did fail and need replacing at that time though.
Hope that helps
i always wash it while the engine is running....first have a spray nozzle attached to the water hose water the engine while its running then use an engine cleaner spray can leave it for about 2 minutes and keep the engine running the spray it back with water the heat of the engine and the spray cleaner will clean it like its a new engine....after you spray the engine with water get an air hose and dry your engine with an air nozzle and you will see the big difference..
Don't have them in that location in my car.
They look like the "ground shoes" that are bolted to the body just below my RR tail light in my car.
It's a splice point to connect many wires together.
If all the wires in them are brown it's a ground connection.
x2 JimLev is correct, they are splice strips often used from the factory instead of butt splices where wires may need to be added/removed. you can absolutely test from them, assuming you know what your doing.
Regarding spraying down the engine bay: I do not know enough about it to give an opinion myself. But I used to work at a BMW dealership for 5 years, and we used to spray the engines (with a high pressure spray gun) for every car that came through for service, as well as any cars getting detailed. Many people at the dealership would bring up issue with this practice from time to time, and the mechanics reassured us that there was no damage we could do unless we held the nozzle within inches of a radiator hose or something. In fact, we even used to spray degreaser all over the engine before giving it a blast with the high pressure hose. All I can say is that after seeing literally thousands of cars get their engines blasted with the high pressure hose, there was never a problem; at least that we ever heard about.
