i guess you have 2000 323i. Not sure if they used trox bolts back in 2000, what engine is that? I know for sure you have totally different engine so you could have bolts .

Bought a used pump off eBay for 80$...should be here tuesday. I am going to put it in either this next weekend or the one after that. I'm putting in a new reservoir too. Looks pretty straight forward.

OK did the job on Saturday, a big thanks to my friend Dave that lent me a nice propane heater so that I didn't freeze my a$$ off. I didn't take any pics sorry but I can confirm that there are 3 TORX bolts holding the pump on to the bracket that it is bolted to. The bracket has bolts holding it on to what looks like and accessory drive bracket, the pump is right underneath the alternator. The job was pretty straight forward a few things to note for people thinking about doing this job. 1. loosen the pulley bolts with the belt on, 2 replace the reservoir with the pump, not sure how many people know this but there is a filter in the reservoir. So on high mileage cars this should be mandatory. 3. Flush your system, now I was able to do this with the pump disconnected (and the car on jack stand of course) turning the wheel from right to left lock to lock the old oil will come out the reservoir to pump feed line have someone ready to catch it as it comes out. Assembly is straight forward, well worth the time as shops will charge you $500 easy or more to do this job. My cost $200 in parts Nice!

LOVE THIS FORUM

beside Pump reservoir and Pump itself, anything else needs to buy together?

just to be sure we have a List of Material needed, which will made this post a great DIY bible for changing steering pump.

certainly, nice, I find out it maybe good to have a pair of clamps too (for the hose connect to the pump), right?
I will try to buy the pump from pelican, which is from Atlantic enterprise, says it's enhance the shaft, looks not bad, and seeing some positive feedback for non-OEM part since OEM LF-20 is not a real "high quality" stuff at all, and and much higher price.

it's really a pain having an aged BMW, just do not have that much time dealing with them and really annoying sometimes.

i bought mine used and the first year i had mine it was like a slot machine every time i got in the car. but after pushing through it i can't get enough of this thing lol the diy stuff is great now that i'm at a point where if something comes up i can replace it by myself, unlike the first year where i had to be dependent on a shop because it broke down so much. partly my fault since it was a VERY impulsive buy (no regrets though) and i didn't do enough research on the vehicle at all.
stick with it, it pays off.

Same here. I bought mine in terrible condition. It lookedas if a prevous owner ddnt care about it at all. He didnt even change window wipers , which made a big scratch on the windshield. I find his black qurly hair , i knew right then it was a black owner. So the windshield wipers were scratching the glass with clear lastic scotch tape, tires were burned until the metal armor was shown. The splash guards were missing. The ignition was giving false codes. Spark plugs were bad. The cooling system leaked. power steering rack was patched with duckt tape. wheels rims were bent and had 4 different size tires on it. I can tell for sure the car also was in an accident, because the way bumper is set. And the grill clamps were brocken off. And i restored it all. Now i have a good car. Much of the work i did myself.

Going to start on this today. I am also going to replace the idler pulley. I have never made a DIY but I have a feeling I might shoot a video. Don't hold me to it!

Last week I changed the OFHG, I was a pretty dirty fellow after cleaning the engine bay and undercarriage after the change. I need to put all the beauty covers and cabin filter holder back on (Changed CCV as well) after this job.

I found a place in Miami that will rebuild my original pump for 125.00 and get it back to me in 3 hours. Power Steering Systems (Hialeah) I believe was there name. They only deal in Power Steering Parts nothing else, so I believe them to be reputable, also they have been in business for a looong time. Will update with results.

1) Is that the serpentine belt? Does anyone know what part number it is?

2) Do you have to loosen both tensioners in that diagram you have above as well? And is it counter-clockwise to loosen that?

3) Do you have to torque it to a certain spec or will I know when it is back in tension?

4) I have an '02 330i automatic, so I believe I have that fan shroud in the front. Will I have to remove that in order to do this DIY? Also meaning I have to buy that special tool to remove it?

Sorry for all the questions, this is unfamiliar territory for me. I appreciate any help you guys can provide.

There are two belts, one for the a/c and one for everything else. The BMW part number is 11281706545. Realoem.com is a good resource to pick up part numbers.

There's only one tensioner to loosen on the main belt. You're not torquing and re-torquing anything. The pulley is under spring/hydraulic pressure, so you're just moving it out of the way to be able to slip the belt out from under it.

It will be easier if you remove the fan shroud, to give yourself some more space to work. Scan these discussions and you'll find how to remove the water pump-mounted fan without the special tool. The tool makes it easier, but it can be done without it.

Just did this but FAIL on my part.
Got everything apart just to find out that my 99 328i comes with LF30.
The one I got online was LF20, I tried to make it fit on the bracket but couldn't find a way.
Thanks for the write up.

Just a suggestion. If anyone forgets to loosen the bolts on the PS pulley before you remove the belt, you can just throw the old belt around the pulley like a noose, and that gives you plenty of leverage to loosen the bolts. No need to completely put it back on and tension it.

I'd definitely use that over vice grips.

Also, in terms of getting the pulley off, if it's stuck on, you can either rent a PS pulley puller (which I did), or just wiggle it off (which I wound up doing when I got tired of messing with the puller).

Lastly, I wasn't changing the pump, just the pulley, and was having a hard time lining up the new pulley with the holes the 13mm bolts go into. I wound up using the two bolts from the PS reservoir up top as guides (they're longer), then putting in the third, shorter 13 mm bolt, then switching out the first two for the proper bolt. Worked like a charm.

My shop only wants $145 for the labor and I can bring my own part. They can get me a remanned pump for $240. So, what do I do? Does someone have a good source for a pump ~$100? I see a few on ebay but it's always questionable....

FYI realoem says I need LUK LF-20

TIA!

I have a question, my car started making this loud nose when turning the wheel to either side. It's not a whine but more like thumping sound can't really explain it. It only makes the noise when I turn the wheel, even slightly. When I give the car gas the noise minimizes.

Power steering pump?
