Power Steering fluid

The fluid required by the power steering pump and I believe the ABC system was quoted by my dealer at $60 for a small container. I found that the local NAPA store sold Pentosin CHF 11S for $21/liter. A Volvo dealer also sells is for about $25.

Check out ebay. I was able to purchase a pint for $11 and $4 shipping. This was the same product that MB was selling for $60 a pint.

My $.02

I use the stuff they have at Napa on my SL55 and my CL500.
Just make sure its the CHF11S Pentosin in the Green Can.

Power Steering Fluid/Reservoir Question

The 2005 SL500 manual makes no mention of the PS reservoir or fluid except to list the fluid in the specs.

Just to be sure.....I think the PS reservoir is right behind the ABC control unit. The very short "stick" in the cap is not showing fluid at all when the car is cold.

Is it time to add some CHF 11S Pentosin from NAPA ?

Any advice will be helpful.

Thanks in advance

The level should be at the correct on the stick. The stick is graduated by 4 lines and two temperature ranges. The lower lines are the high/low level for cold/ambient and the upper lines are for when the fluid is hot. It is a little confusing for some. To make it easy, check the fluid when the car is cold. Just be sure your fluid is showing on the stick and not too high or too low. So yes add fluid.

My 2004 SL55 had only 3500 miles so low PS fluid was not something I would have looked for. There was a stored PS fluid fault that my buddy found when scanning my car with a special diagnostic tool. He had to clear a bunch of faults I assume were due to the car sitting for a very long long time with dead batteries. Most of the faults were never displayed. The big red battery fault that required you to go to a dealer was the one I wanted cleared. He found a bunch of stored faults for virtually every system in the car. I wanted all cleared to see if any come back. My next goal is to get the SOS and Phone systems disabled. Im looking for a shop that can do that. My buddy does not think his tool can do it.

Found local NAPA has it for $21 so I'll get some and add a litle at a time when cold to hit the lower two hashmarks.

Thanks for the advice.

Had to buy the liter can for $20.99 + tx. Reservoir needed only about 2-3 ounces to hit the hashmarks on the short stick.
The rest of the can will sit on the garage shelf for a long time.

I believe the ABC system uses the same fluid. You may need to top off it at some future date too. It won't be wasted.
