So are these instructions applicable to a '04 330i ZHP? One of the posts on page 4 made it sound like the 330 is different from the 325 (and for sure the M3). Did I read that right?

I know it's repetitive, but great DIY write-up and fantastic photos!

Sorry. Auto. Just did a visual and it appears my fan is attached to the engine. Looks like I need to buy the tools from BimmerTools (32mm Fan Clutch Wrench
and Water Pump Pulley Holder). Or are these tools I can borrow from an auto parts store?

Many thanks, dude! Saved me about $170. I have a 325i automatic so I had more work to do to get the fan/shroud off. Someone else had a post showing this process using a solid whack with a 32mm wrench on the fan clutch nut so you don't need the fancy clutch-holding tool. Worked great! The photos were outstanding.

I just finished checking my pulleys and changing my belts. I found it better to get a 16mm socket on the spot between the A/C and the tensioner pulley instead of directly on the tensioner pulley.

Thanks for the excellent job on this DIY. Serpentine belt was in shreds - no question what the problem was! Followed your directions to a 'T' and then notice that I don't have an idler pulley! (aha! The source of the shreded belt - didnt notice that until I looked at the good pics from the article).... The bearing assembly must have failed completely - found the pulley in the engine pan...no sign of the bearing assembly anywhere! The Autozone up the street had one in stock for $38 (thank god) - rushed back, put on the new idler pulley and had both belts on in under 10 minutes. Thanks again!

How much coolant did you bleed when repl. w. pump?

Hate to start a thread just for that ... searched and couldn't find it ... How much coolant did you guys have to bleed to replace the water pump? ....and while I'm at it; a little heads up ... an 01 with a production date 00 supposedly have mechanical tensioner. Mine was hydraulic!!! Go figure.

Started noticing a squealing coming from my belts/pulleys. Whats the best way to diagnose which pulleys need to be replaced (Belts are OEM and I replaced about 15k miles ago so they should be good)? In particular, what kind of "play" should I be feeling for? Btw, I have an '01 330xi w/ mechanical tensioner, and pulleys and tensioner are originals.

the bottom belt (forget which it is) can be done with the car on ramps from the under the car - took about 10-15 minutes

for anyone who has the fan bolted to the engine - please post some pics/a how to on its removal

I am having a hell of a time try to get a wrench to fit around the bolt to unscrew it - i just cant seem to get it down there in good position and get it turning

some pics and a short writeup would go a long way to assuring me that I am doing the right thing, and to assist me in actually doing it

I'm going to be replacing my mechanical belt tensioner with another mechanical one, as well as the deflection pulley

I have a few questions before i proceed this weekend:

In order to release the tension to release the belt, i must turn the following hex nubbin on the mechanical tensioner clockwise. Ofcourse it wont turn cause its part of the metal mold of the tensioner body??.... but it decreases the tension enough to allow the belt to be released, correct?

The following pics show what reffering to:





Attached below is a pic of a new mechanical tensioner, showing the hex nubbin, from here it appears as though there is an outer and inner section, and so when the hex nubbin is turned clockwise IT WILL ROTATE . I'm picking the part up tomorrow so maybe it'll become clear then.


SECONDLY in order to get the belt back on, first do i tighten up bolts #3 to their corect torque specs or torque them fully later (in diagram below). Then do i ROTATE the same hex nubbin CLOCKWISE again, to decrease the tension allowing the belt to slide back on??

Wow, great write up. I laughed at a few parts because the way you wrote stuff is exactly the way I thought it in my head as I was doing it. Getting the wire off the fan was the hardest part!
