Just in case anyone with an M3 is looking at this, our fans are NOT electric, and do NOT slide right out (with shroud) with ease, like they do in this DIY.

You'll want a 32mm open ended wrench, and a fan clutch tool to hold the fan shaft while you loosen the bolt (it's a left hand bolt, so you turn it to the right as you face the car to loosen).

The other parts recommended here work just the same, but the fan and shroud are different. Also, there is part of the shroud near the airbox that is integrated AROUND the top radiator hose (!), so it tends to get in the way when trying to get the radiator fan shroud off).

It's a PITA. Plan ahead. Be patient.

My Ride: E46 320d 02
Hey guys... NEED HELP!

sorry i am new on this. Recently bought a 320d 02 Auto with 87k on the clock. On the way home the other night the climate control belt just came off... thought it wud be easy to put back on but wrong.

I could reach in and take the belt completely off, no tear marks or cracks and it had an inspection II (worth nothing!) when i bought it, but i thought might as well replace it now. So now to get to the drive belts... On my old E36 u cud undo the screws for the fan housing and lift it out. But on the fan housing for this it is a full housing and the fan just stops it coming/lifting straight out. RealOEM link below...

http://www.realoem.com/bmw/showparts...17&hg=17&fg=05

I know i must be missing something simple but how do i get it out? I thought maybe u might have to go underneath, undo the fan bolt then take out together but the fan housing will stop you getting at it. Am really confused and seriously need help on this... (yeh yeh shake ur heads while saying noooob - i deserve it!)




I've got other power issues with this car, replaced the maf bit better but still no turbo till 2.1k revs... might try the pierburg MAF heard good things about it. otherwise still no power uphill and in 5th on the motorway can barely manaage 70 mph up any sort of incline. Its like the turbo is dumping pressure so no boost?? changed pressure convertors and vac lines, turbo breather air filter... But this problem is for another day....

That's funny. That's the problem I was running into. But, I have a 330i. I'm assuming mine is like that because I have an auto and the fans seem to be setup differently.

My Ride: '02 325ci & '04 r6
...

replaced my belts today on a 02 325ci. took me about 2 hours because my fan is not one piece with the shroud.

my fan is belt driven and what i did was loosen the shroud and looking between the radiator and the shroud you can see that the fan attaches to the belt driven shaft with 3 screws. to avoid running to the store again, i used a 27 or 30mm torx bit to unscrew the 3 bolts (i don't know the actual bit needed, but my technique worked)

after doing that you can remove the shroud and fan and finish up using the DIY. i didn't need any other specialty tools but that shroud is a ***** to get seated correctly again.

good luck guys... its harder, not impossible...

Ok, trying to do this, however, I cannot (for the life of me) figure out how to get the belt back on. I've got it (the serpantine) threaded properly and sitting over the hex nut like it was suggested but I cannot figure out how to get enough tension to get it over the pulley. Any help????

Thanks.

Ok, thanks for posting this great DIY but I wanted to add something which had me stumped for a few days. When you're putting the new serpentine belt back on, in order to release the tension enough in order to get the new one on, you have to put your torx head into bolt number 7 (see below) and tighten it. Then, once it's all the way as tight as it can go, you must keep trying to turn it in order to release the tension. It's not easy to do, you'll need to put some omph into it. I used a breaker bar which made it quite easy. But that's a trick I've not had explained anywhere in any of the DIY articles for changing the belts.



Thanks again for a great article!

Will be doing this in the next month or so, excellent write-up!

I noticed the belts were looking worn when I did the thermostat about 15k ago... was picked up on the Insp 1 last week so need to get on with it really! Main dealer quote was amusing - 65 (approx $90) just for the altenator belt. No labour...

My Ride: 99 323i
Let me add my 2 cents. This is a great writeup, since I just had my 99 323i towed back to the house after breaking the water pump/power steering belt and leaving me stranded. Fortunately it was 4PM when I called triple A and I was back home by 4:30. This E46 forum was the first place I went for help and if I can get the belts in the morning, I'll be sure I have the right torx bits and will do this tomorrow. I replaced the wiper motor assembly on Tuesday with the idea of posting a DIY. As soon as I get the belts replaced I'll do the motor DIY and post it.

Sorry about your 323i.. Yeah the E46 forum has helped me a lot since I joined.

Definitely post that DIY! Why did you have to replace ur wiper motors anyway?

My Ride: 99 323i
Went to the snow area around Lake Arrowhead for romantic Valentines Day getaway. Snowed, roads plugged up, crappy cable chains just barely better than nothing and to add to that, the windshield wipers quit. The snow was wet and kind of heavy but didn't seem that bad and I thought that maybe they had frozen to the windshield. I freed them up but still no luck, then as I was about to pull over and stay until summer, they started working again only the rest position was straight up and down. They still wiped, but from the 12 o'clock position, they went to 3 and than back to 12. Sooooo, I got a replacement from a recycler and replaced the trim at the bottom of the windshield while I was at it.

Oh lol. Interesting story. Records show that my windshield wiper motors were replaced around 8700 miles... so I was wondering.

For my car, an '02 325i Sedan, the main drive belt tensioner (not the A/C belt tensioner) used an 8mm hex bolt for the center tension release mechanism. Some cars use a T-50 here also (in addition to the one for the A/C). But not mine.

If you look at the diagram in post #67 above, bolt #7 was an 8mm hex on my car. Hope this helps

My Ride: 2003 330 Ci converti
the tensioners have an easier way to 'de-tension' ...

If you look at the tensioners, there will be a fitting to put a bit/breaker bar without needing to take the cap off and/or use the center of the pulley.


first, the A/C tensioner has a recessed torx T-60/T-55 slot [the T-55 was the biggest one I had; it was a tiny bit loose but worked ok]. The pictures are from below, front side 'creeper' angle.

The main tensioner uses a stud for a 16mm socket - approx 18" long 1/2" breaker bar works just fine to loosen.
