Does anymore know where the Power Steering Resevoir is located on a 2010 Porsche Cayman? I need to added some Power Steering Fluid and/or flush it. Thanx in advance ...

 

You have to take the engine cover off and I believe there are 2 resivoir caps in there ,1 is the coolant overflow and the other is the power steering filler
As far as my memory goes its the black one!make sure you use the proper fluid

 

And that is the Pentosin CHF 202 Synthetic Hydraulic Fluid?

 

Yes ...with lots of German written words on the can

 

if it is like the gen 1, it is toward the front left of the engine (behind driver seat)

 

My write up here...the last page has picture of PS dipstick/filler location picture. While you're in the engine, worth it to check and possibly replace the air filter.

Good ATF is way better than CHF as a PS fluid. ATF+4 is what Mercedes uses. VAG uses CHF 11S in the same hard parts, and the thing die like flies. Leaks are common from over heating and warping the seals.

CHF is simply too thin to protect the pump under real world conditions. It's more like an aircraft hydrolic fluid for extreme cold. Once the lubricating properties break down from heat, it allows more and more metal scuffing in the pump....causing runaway heating, even hotter. Guys pull shrapnel out of busted system by the handful.

Keeping it short, ATF is thicker and contains more and better anti-scuffing additives. ATF also has a slight seal-swelling effect, helping with worn or dirty seals.

I changed to ATF+4 in the 2002 Boxster (43k). I used the easy turkey baster method. I could only extract a small amount at a time, unlike most vehicles w/a normal reservior. Refill, then run the motor to mix it all, extract and repeat. You'll know the progress as the fluid goes from burnt tan to red. I believe it too me 10 cycles to use 2q. A helper is a plus. There are other methods to get a full flush....like when your unit dies!


TRUST me on ATF as PSF. I don't want to labour it, but clean fluid with robust additives, that's a hair thicker is a very good idea. I've seen dozens of cars switch over, no one had a failure.

ATF+4, a licenced formula, all brands are the same, $4 at WalMart. Used by MB and Chrysler.

New M1 ATF

Dexron VI Used by GM (or good Dex III, like older M1 ATF)

"Multivehicle ATF"

Mercon V should be good if that's what you happen to have.

You can flush it with ANY ATF, old Dex 3 even.....for the first quart.

Don't use Hi-Miles ATF, too much seal swell.

Not that I had any concern in the world, but the Boxster's been on fresh ATF-PSF for 3 months, 5k miles...still nice and quiet. It's instantly smoother.
