Power Steering Pump Replacement

Hi, this is my first post and I appreciate the helpful information others have made available on other issues. I intend to post a description of my latest adventures when all of this is over or I am at least a little farther along, but right now I could use a little help on removing my old power steering pump from my 2003 325ci convertible that recently turned over 100,000 miles.

I have searched the internet looking for something that will tell me exactly how the pump for my car is attached, but haven't found anything for my model. My new pump and fluid reservoir are due to be delivered today and I spent an hour Saturday getting everything ready to install them. I removed the fan and shroud as well as the old fluid reservoir and the pulley on the pump. I then removed the 3 torx bolts that were behind the pulley and the metal fluid tube going into the pump and have drained most of the old fluid. So, I know I'm close, but I can't see what is still holding the pump firmly in place.

When I get the new pump, I hope I will be able to see what other bolt or bolts need to be removed so I will know more about where to look, but I thought it would be a good idea to see if anyone out there can offer some advice or direction just in case. I believe there is a bracket that the pump is mounted to, but I can't tell if the bracket has to be removed with the pump or whether I can remove the pump from the bracket and leave the bracket mounted to the engine.

The heat exchanger for the transmission fluid is blocking my view a little, but I had rather not have to drain the coolant again (more on that later) if I can avoid it. Thanks in advance to anyone who has been through this and can tell me what I need to do now.

Thanks, but I had already seen that post. That is on a 1999 car and the pump is similar, but significantly different from the one on my car.

Have you tried hitting it? I'm serious. If it's anything like that other car, it's corroded on. Don't hit it too hard, but since you're replacing it, it's not hurting anything. If there really isn't anything else connected to the pump, then this won't pose a problem.

I did tap on it a few times, but I didn't want to get too rambunctious until I confirmed that those three bolts were all that's holding the pump on. You're right that I have nothing to lose as far as the pump is concerned, but I didn't want to damage something I couldn't see, so I thought the prudent thing to do was confirm first, hammer away later. If someone tells me that those three bolts are all there is, then I'll know. Or, when I get home I may be able to determine that by looking at the new pump. This looks like it is a pretty straight-forward operation. The local dealer, who tends to be fairly reasonable compared to some others, wanted $1,030 to replace the pump. I was able to get the new pump, reservoir and the hose that connects them for $262. After I'm finished I will post a report for anyone who is interested. Thanks
