Hi cn90,
Looking at your wonderful cooling-system DIY, I noticed my belt(s) were cracked just like yours in your step 6 photograph. Little teeny tiny cracks all over the place. Is that bad?

Actually, I don't think I wanna' know the answer, do I? I'm not in a mood for a complete overhaul (too many other things on my mind right now). Mainly, I dread removing my belt (for all the work it might involve) but I fear I must do it now, in the warm garage, or ...

Any specific advice on what else to do if I get the courage to tackle removing and replacing the belt (on a 525i)?

Hi bluebee,

Cracks on the ribs (the raised edges) is normally seen at 50-70K old.
Best is buy the Conti belts (qty = 2), leave them in the trunk in case you got stranded somewhere.
The only problem is in order to change the belt, you need the 32-mm thin wrench as well.

Then when it comes time for cooling overhaul, you can install the belts then.

Or just change them now and worry about the cooling overhaul later.

Hi cn90,
Good idea to buy the two belts now and leave 'em in the trunk just in case.

I see you also also bought "rollers" & "tensioners"; (I have a noise upon startup which I still haven't identified the cause of yet - maybe it's one of them.)

I'll have to look up why"Conti" is better than, say "Dayton" (which I found more of in my searches) and what exactly "32mm thin wrench" I need ... but that shouldn't be too hard of a search.

In general, I don't mind buying tools or good parts as they're both cheaper than labor. I see you replaced for your 98 525i about $175 in parts, namely:
* $9 - AC belt 5PK0906 $9
* $13 - WP-Alt-PS belt 6PK1560 $13
* $34 - Rollers x 2 PN 11281748131
* $23 - Idler Roller PN 11281738605
* $39 Hydraulic Tensioner PN 11281717210
* $50 Hydraulic Tensioner PN 11281717188


Searching a bit, I notice in the picture below that some try to sell v belts to replace the serpentine belt, apparently - and that there was a change in belts at 9/2002 (my 2002 E39 was built in late 2001) ... so I think I need to be careful exactly which belt I end up ordering.

PS: Searching, I found this E36 belt-only DIY and this E38 belt R&R and this M5 belt replacement and this

The thin 32-mm wrench is need to remove the Fan Cluth in order to change the belts.

If you have more than 80-100K, do a cooling overhaul anyway. The DIY I wrote is for 98 528i. Your car (2002 525) is slightly different, so you may have to look for some other DIYs for completeness. I think someone wrote a DIY for M54 cooling overhaul recently but I cannot remember who.

Yes Conti = Continental = OEM supplier for BMW.
Dayton is a USA company, probably good too, I just don't know enough about Dayton to say anything.

PS: "edjack" is also in San Jose CA, maybe you can PM him to see if he can offer you a hand???

Is that thin-32 mm wrench somewhere in this set of diagrams?

115040 is the thin wrench.
You can buy it online or somewhere locally.

I sourced my parts at autohausaz.com for the tensioners and belts.
