Long story short my power steeing pump is heading south. I have a new one on hand and hoses and o-rings on the way. So has anyone had to do this yet? It doesn't look very easy to do as it's situated above the aircon compressor.

 

Any tips or tricks would be greatly appreciated.

 

Thanks,

John

Sorry I can't help with replacing the pump as I've never had to do one yet but just wanted to give a word of warning about the fluid, be very careful as it can damage plastic,rubber and some painted surfaces so if you spill any be sure to throughly clean the area.

 

What are the symptoms your P/S pump is displaying that it needs replacing?

I really don't want to admit this publicly but I did on another forum anyway so, I pulled a REAL bonehead move when doing my brakes and pumped my power steering full of brake fluid. What can I say, it was late at night after a full weekend of working on the brakes and I just wanted to get done. I figured out what I had done a couple days later and cleaned it out and replaced with new PS fluid but I think the damage was already done.

 

Now the pump makes noise and is getting notchy. Looks like either the pump or the hose lines are leaking now too so am replacing them at the same time.

 

The rest of the parts are supposed to be here Thursday so I may tackle it this weekend. I just replaced most of the presure hoses too but am still having issues with boost loss so I need to look at getting all the vacuum lines done too. One thing after another!!

Same with me. Pump is gone. Loosing Fluid and making unusual noises. I guess this part has to be replaced.

You did it by yourself?

I have the pump, new supply and return lines, o-rings, and serpentine belt but haven't tackled this project yet. Yes I plan on doing it myself. It doesn't look too complicated except getting to the pump itself. It's up above the AC compressor. I'm afraid the steering pump won't come out without removing the compressor but I'm hoping it will. My CTT is my daily driver so this will have to be a weekend project and this coming weekend doesn't look good, too much other stuff going on.I'll try to remember to come back an update when I do get it done though.

The pump will come out without taking out the compressor.  I went in from the drivers side wheel well and from the engine bay to get it out.  You must remove a great deal of items.  It took me about 8 hard hours is a real bear but is doable.

8 hours!!! Jesus thats a lot. Looks like i need the shop . Thank you

 

 

Yeah it doesn't look like fun. After my last post I did some more searching and did find this that should be helpful....http://workshop-manuals.com/porsche/cayenne_turbo_s_(9pa)/v8-4.5l_turbo/steering_and_suspension/steering/power_steering/power_steering_pump/component_information/service_and_repair/

 

I still don't think I'll have time this weekend. Saturday I am going to see a tech session with a 918 that should be fun!! If I'm feeling really brave I might attempt it Friday night. I've already got the lower and upper covers off the engine bay from previous work so that will save me some time. (edit) I have also become very proficient at removing the filter airbox since I spent some time chasing boost leaks. A tip here is to make sure you only turn the plastic screws that fasten the pipe to the box until they line up with the opposite mark. I broke the ones on the intake plenum the first time I took it apart.

Thanks. Any tips other than how to get at it? From the link I posted above one important one that I hadn't thought of was to loosen the pulley bolts BEFORE taking off the belt. Makes a lot of sense!

Not really, I found a low mileage used pump that came with the pulley so I did not have to remove mine.  It is very straight forward as to what you have to take off, just takes time.  Bleeding the air just takes a few full locks of the wheel after you get everything back together.
