Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
This is a light oil type fluid - not clear. There are now two leak 200mm wide patches that have penetrated the concrete slabs of the drive. One patch is immediately in front of the front n/s wheel coming from the under tray (below the ABC pump?)and the other next to this in front of n/s wheel but just inside.
I haven't started or moved the car since I sent the first enquiry.
The 'dipstick' in the larger front unit with ABC label shows fluid mid-way min - max. However there is a conical pot behind with a stubby dipstick which does not register although I can see some fluid in the pot.
Is the main reservoir the conical pot with low fluid level or the ABC front unit which has a filler and dipstick? I will need to top up as I have made an appointment to get it looked at next week at a specialist and will need to drop the car off
I will look later at the hp pump behind the wheelarch liner - no doubt that is the culprit which I understand is costly to replace and cannot be repaired?
Do I top up the larger main reservoir (front unit) labelled ABC with the small filler neck with dipstick which has still got fluid up to between min-max or do I top up the near empty conical pot sitting behind (is that a header tank?) as the diagram doesn't show both pots. I note that there are 2 pipes off this conical pot - a 30mm pipe heads to a nearby pump driven by the main pulley and the 2nd about 15mm pipe heads towards the front grille area?
Sorry I'm still asking questions...
Im sure that the larger main reservoir is the front unit and marked A..B..C. It has the two sided dipstick but the fluid level is within the indentation i.e ok. So I cant top this up with Pentosin without overfilling??
However the conical pot behind which I think may be for the power steering is virtually empty and one of the outlet pipe heads towards the lower front wheel arch where I believe there may be a radiator? Can I use Pentosin for topping up that container to check loss?
Yes I need to remove the inner wheel arch liner to see the culprit of the leak.
The image shown is different from my SL500 engine bay. Mine does not have the smaller (PS) vessel in the front. Also the box shaped thing with the 4 bent metal pipes is on the offside wheel arch. The larger main unit (Oil Reservoir) marked A..B...C on the label and Hydraulic Fluid on the hose cap is the same as mine but I have a black conical pot, marked on both sides PA 66-GF, immediately behind which is virtually empty of fluid which I assumed is the power steering reservoir?
Can you see in my picture?
Sorry I should be adding Ratings
Hellothats right the pot to the rear is for power steering fluidhowever the Dextron is a dark red so don't think thats your fluid leakbut yes it sounds like it needs filling upchecking the level of this should be performed after a drive so as to warm the fluid as it expands a lotso top it up to about halfway before driving then cehck again afterwards
