What was that fluid?
Discussion
Hi All, hoping someone can provide some info.
Got an SLK55 2005 (R171) M113 V8.
Took the front wheels off to clean them properly, and the brembo brakes. While wheels off and up on stands I turned the steering wheel lock to lock a handful of times to get better access to the back and sides of the calipers to clean them. Engine was not running and no power steering operating obviously, and as wheels off, not much resistance thru the wheel.
Put wheels back on, off stands, car in garage job done.
Noticed a small stain (side plate in size) on the floor, seemed to be clear fluid and oily in nature, not water based.
Some dribbles noticed on the under tray as well. Nothing on floor in garage since car has been put back so I can only assume it 'weeped' out of the steering system when I was turning the wheel to aid cleaning.
Anyone care to advise what might be the case.
As I say no leak or weeping now, either on garage floor or on under tray.
When a power steering system is not pressurised and is turned lock to lock, is it prone to weeping some fluid? I thought P/S fluid was red?
Cheers in advance,
Adam.

Okay the fluid seems to be the same as what is housed in reservoir A0004600183 part number embossed on it. This is a power steering reservoir. The fluid is a clearish light urine color (sorry!) And has an oily texture. Cap off, and it has a dipstick on the cap, with a max min at 80degrees range,and a max min at 20 degrees range. The level is reading at max mark in the 80degrees range on the dipstick when engine and fluid is all cool and at ambient temp.
Gut feeling is it is overfilled and spuing out / pushed out of PS system somehow when not under pressure and turning the wheel per original post.
So, with this info now added to thread, be interested in further comments.
