DIY- PS Pump and Reservoir change

adam699 · 09-04-2008, 02:06 PM #1

I'll edit this with media in a bit. Here's the step by step it's actually quite easy if you are mechanically inclined. I'm not gonna go into details on Air Filter or Belt removal as I think that if you cannot master this one yourself you got no business going further

I take no responsibility if you damage something or hurt yourself.

(There is excellend writeups on rennlist that covers these 2 steps)

1. Remove the Air Filter Assembly

2. Remove the 2 bolts retaining the Y-pipe, Loosen 1 clamp by the throttle body, disconnect the boost hoses from the y pipe, slide off a clamp on the drivers side connecting the F pipe, remove 1 bolt attaching the AC clamp to y pipe. Yank the Y pipe but be careful as just under the throttle body there's a tiny vacum tube going to a selenoid that needs to be disconnected.

3. Losen the bolts to the Pumps pulley

4. Release the belt ( you dont have to remove it but just slide it of off the pulley)

5. Remove the pulley. It will come out but you might have to stick your hand behind ther pulley to turn the pumo 1/3 of a turn to clear the frame.

6. Look closely for a wire that goes to the front of the AC compressors clutch. This will determine if you can remove the reservoir and pump as one complete assembly. If the wire passes between the pump and the reservoir you will have to remove them seperatelly.

7. Have plenty of rags as there will be some spillage and Pentosin is not nice to rubber hoses. If it comes in contact with coolant/boost hoses wipe it off and rinse with water immidiatelly.

8. Suck out as much fluid as possible from the reservoir. I used a nice $20 vacum pump with a little jar used primarely for bleeding brakes. At one point you will notice that you cannot go any deeper because of the strainer. I noticed that if you stick your finger in there you can patiently wiggle it out. Just try not to damage it so be gentle

Once the strainer is out siphon the rest of the fluid out of the reservoir. The more you get out the less of a mess.

IF REMOVING THE RESERVOIR SEPERATELY

9a. Remove the return line going into the lid of the reservoir by pressing in the red ring and pulling on it at the same time. It should release like butter.

9b. Remove 1X 10mm bolt hidden behind the reservoir. Remove the 2 13mm bolts on both sides of the reservoir. (the one on the drivers side is a pita to get to, I'll post a video of my wrench rig that I used to get it out).

9c. With the rags ready, yank the reservoir sttright up and fish it out to safety

9d. Install in reverse order.

IF REMOVING RESERVOIR AND PUMP AS AN ASSEMBLY

9a. Remove the return line going into the lid of the reservoir by pressing in the red ring and pulling on it at the same time. It should release like butter.

9b.Unscrew the hi pressure line from the pump at the "bronze" junction using 2 flat 15mm wrenches. Have rags ready and i used the vacum pump to keep suckingg out the fluid until it stopped draining.

9c. Unscrew the 3 bolts that attach the pump to the bracket. Yes there's 3...the third one is hidden under the pump shaft and is hard to get to. I used my "wrench rig" to get to it.

9d. Remove the 2 13mm bolts on both sides of the reservoir. (the one on the drivers side is a pita to get to, I'll post a video of my wrench rig that I used to get it out).

9e. Now you should be able to lift the pump(you might have to pull on the AC lines to get clearance) to clear the bracket, turn it clockwise 1/4 turn vetrically, and slide it towards you from the bottom (pump first).

Installation is in reverse order.

any tips on how to remove this bolt??

smistry007 · 10-18-2008, 09:42 AM #3

excellent write up- thanks for posting!

Lowered the engine and replaced my secondary air pump, change over valve and 3 check valves-and I forgot to take pictures. You saved my life!

Looks like I missed this post a few months back. Looks like your car is a manual. Mine was a tip and didn't have these lines. They do look like "brake line" type fittings. I'd either use a flat wrench or if it is really stuck, vise grips usually work best for me.

Hey guys, I still can't get that one bolt off that I circled in the picture.
I've even tried a brake line wrench.. any other tools I can use???
if i turn it anymore then it'll just strip.

Brake line wrenches suck as althou they are HEX they still flex because of the slit and will round these out. Vise grips set up right will grip it strongly enough not to strip it. Also, since the fitting is steel and the reservoir is aluminum, soak it with a penetrator first. Worst case scenario, you'll learn how to use a double flaring tool

Thanks for the tips.
I finally did it. I officially hate Porsches.. so far I've replaced spark plugs, intercoolers, clutch accumulator and the power steering reservoir.
ALL of those are harder than any car I've ever worked on.

Also, when I took the drive belt off.. I didn't line the pulleys in the same spot as they were before.. now they're all outta whack.. is that ok???

SXN,

How did you finally manage to get the lines off? I just started hearing this noise today and I think I may try to tackle this job in the near future. When I changed the alternator I didnt line the pulleys up and have not noticed any ill effect. Did you change both the pump and reservoir or just the reservoir? Has the noise gone away with the change?

Thanks

I took adams advice and used vise grips. Worked like a charm.
I replaced the reservoir, there's no need to change the pump.
It's a 997 reservoir that you replace it.
put aside a lot of time for when you do this. There's some tricky bolts man.

Glad it worked

Make sure you guys tighten them up pretty good, but not too much. Also you have to be very careful not to cross thread them. It's best to just clean'em up real good and use your fingers for the first few turns. Also, triple check for leaks after you run it and use the clutch/PS.
