323i: Changed power steering pump in 2000 bmw 323i. Still not

This answer was rated:

Changed power steering pump in 2000 bmw 323i. Still not working and now car overheating. Changed steering rack too do to a wreck.

Fidhle007 :

Hi There! My name is XXXXX XXXXX I'm a BMW Tech!

Fidhle007 :

There are two different pumps for your car, one is a higher pressure pump and is probably the one you need. I ran into this issue with a customer's 323i last year.

Fidhle007 :

As for overheating, I'd look elsewhere especially since it's been in a wreck.

Customer: Hi. My name isXXXXX if son Davey who wrecked this car 3 weeks ago. Do U have any idea what they might have done wrong putting new pump and pully in?
Fidhle007 :

Thermostats are common failure points on E46 cars and I'm starting to see radiators fail as well.

Fidhle007 :

Hi Nikki! How bad was the crash? Is everyone ok?

Customer: But it wasn't over heating till we changed pump?. U think because wrong pump in?
Customer: He was ok..:). But broke steering rack and bent the arm, which all been replaced too.
Fidhle007 :

Do you have the VIN of the car at hand?

Customer: I can get it
Fidhle007 :

Thanks, XXXXX XXXXX be helpful!

Customer: Wbaan3340ync92530
Fidhle007 :

Thanks!

Fidhle007 :

One second...

Customer: We got pump from autozone. I told my son and his dad that I bet they have us wrong pump. His dad pretty good mechanic too. But he couldn't fig this out at all.. L
Customer: Did I give u correct vin?
Fidhle007 :

Yes, I'm just checking some part numbers

Customer: Ok thanks
Fidhle007 :

How quickly is the car overheating? Right away or is it just after driving a ways?

Customer: Just after driving it for a few. And he said fans running too. He changed oil and put new antifreeze in as well when he was done
Fidhle007 :

Ok, that's it!

Fidhle007 :

These cooling systems need to be bled in a specific order

Fidhle007 :

otherwise they trap air and will overheat which is probably what you're observing

Customer: I build Hondas here in Ohio. I tried to talk that boy out of this car. Told him it would be a pain in the butt to get parts and fix. But I guess I'm bias.. Lol
Fidhle007 :

Haha, and here I have no idea how to work on Hondas!

Fidhle007 :

Anyway, simple procedure:

Fidhle007 :

Remove the radiator cap and the large bleed screw next to it.

Fidhle007 :

Fill the expansion tank slowly until coolant pours out the bleed screw

Fidhle007 :

close said bleed screw.

Customer: Ok. While car running?
Fidhle007 :

No, with the car off.

Fidhle007 :

I'm sure there's a special tool for this but at my shop we use an old turkey baster to suck some coolant BACK OUT of the tank.

Fidhle007 :

Just until the little red float stick is just above the top of the cap.

Fidhle007 :

Then close the cap and go drive with the heat on. If the car doesn't make any heat, try it again!

Customer: Will this make power steering pump turn on?. Or u think they gave us wrong one?
Fidhle007 :

That's for the overheating. The power steering pump is probably the wrong one unfortunately.

Fidhle007 :

You're looking for either 32416760036 or 32411094965 BMW part #s

Fidhle007 :

and while you're in there I'd replace all the hoses as well if you haven't already

Customer: Ok. U have helped so much. Thank u., can I email this to my sons dads email so he can read it and understand it better than me.. Lol
Customer: All hoses which are?
Fidhle007 :

There's a link to the pump part numbers and some of the hoses as well

Customer: Are those part #'s for the pump we need?
Fidhle007 :

You'll have to cross reference which one came out, there are two and I can't tell you which one you need from here

Fidhle007 :

But if you can't figure it out, go for the Luk 30

Fidhle007 :

it's the more powerful one and probably the one that's supposed to be in the car.

Customer: Ok. I'm sure that's not to hard to fig out. I think I can handle that part. Lol Thank u
Fidhle007 :

Like I said, I had the same situation on a 323i last year. The pump failed, I replaced it and it didn't work. Ordered the more powerful one and it was golden!

Fidhle007 :

There's some more of the hoses

Customer: Good!. I hope that fixes it. Just hard cuz he works and football. And I work 2nd shift. And his dad always running my younger son. So him not having a car has been a pain..
Fidhle007 :

Between those two diagrams you should be able to cross-reference all the parts you'll need! And like I said, bleeding the coolant should help and if it doesn't, go after the thermostat. It is common to have them fail and they are easy to replace.

Fidhle007 :

Good luck, let me know how it goes! I know how it is to be stuck without a car!

Customer: I will. Appreciate it help!. Thanks again
Fidhle007 :

Thanks! Please don't forget to leave me a positive rating!

Fidhle007 :

If I have been helpful, please accept my answer and leave me a positive rating! If you have other questions I'd be happy answer them!

Fidhle007 :

Thanks and good luck! ~Brendan
