Nice, Bluebee.

My goal is to look at my engine compartment, and know at least what the name of everything that can visually be seen is.

Do you also see non-visually? Or is that language from the Department of Redundancy Department?

Good point. My writing mirrors my personality, which is far more loquacious than reticent!

Here is a picture of the auxiliary water pump from underside my M54 engine:
- AAA is towing my car in 30 minutes (total electrical failure)

Here is a clean shot of my M54 engine Bosch 120 OEM alternator, with the airbox removed so it can more easily be seen:
- AAA is towing my car in 30 minutes (total electrical failure)

And, here, circled, is another view of my VANOS solonoid adjusting unit:
- AAA is towing my car in 30 minutes (total electrical failure)

Yet another VANOS solenoid adjusting unit on my M54 engine, this one (gunked up) under the apparently leaking valve cover gasket:

Here is the idle control valve (ICV) on Michel's ( mmm635) M54 engine:

And, circled is a good view of Michel's starter motor:

And, here is my fan clutch as I try to reattach it (crookedly) to the waterpump of my M54 engine:
- AAA is towing my car in 30 minutes (total electrical failure)

Here, from underneath, are the tensioners and pulleys for my M54 belt-drive system:
- AAA is towing my car in 30 minutes (total electrical failure)

And, here is the diagram from the Bentleys of the M54 belt-drive system:
- AAA is towing my car in 30 minutes (total electrical failure)

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.

Looks like others are asking what this part is also:
- P0174, P0128, P0171, P0313.. New Bimmer and need help

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.

Bluebee, that looks like a starter solenoid with the larger round case below the actual starter motor.:thumbup:

Thanks Mark.

You've helped a lot on this thread; and I appreciate your efforts!

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.

Today, I ran into this picture from 16valex of an E39 engine part from this thread:
- E39 (1997 - 2003) > 2001 525i, pcv location-replacement

What it is, though, I'm not sure.

16Valex was responding to this post:

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

So, I 'assume' this is the 'purge valve' from the prior discussion; and, it may be worth noting the picture itself was saved as 'breather valve'.

Maybe we should just stick to engine parts ... but this is pretty:
Wheel speed sensor

Hm, that's the front. How does the one in the back work? (sorry to go off topic).

 

[bluebee]

How does the one in the back work?

Are they not the same?

BTW, today a poster asked about this part below.
- E39 (1997 - 2003) > Help ID this Part??

It turned out to be either the rubber boot at the bottom of his radiator (which means he probably has a tilted radiator) or a part of the air-filter housing.
