Wondering if Pentosin CHF 11S is a suitable fluid for the power steering system on an M103 (1991 300E). Thanks.
Can anyone else confirm that Dexron III is a suitable PS fluid for this particular W124? I'd much rather pay $3/qt for Dexron III ATF to flush/fill the PS reservoir than paying $12/qt? for MB PS fluid. And Red Line make good products too, but $11/qt is not much of a break either.Apparently not (look at the document that was attached in the 3rd or 4th post: http://www.benzworld.org/forums/w202-c-class/1273555-question-about-power-steering-fluid.html
It's used for the newer models. According to MB, dextron transmission fluid is a better alternative.
According to my records, ATF has been in my power steering system for close to 120k miles. I show no signs of leakage, wear or abnormal noises.DO NOT use ATF for your power steering fluid. Mercedes specified ATF in the W123 series and changed to power steering fluid for the W124 series (not certain of the date). ATF, with it's friction enhancers, has been found to cause premature wear to internal parts of the steering box over time. GM and many other manufacturers changed their recommendation many years ago. Ask any steering box rebuilder about the difference in demand for steering boxes between the W123 and W124 series - dramatically higher replacement percentage in W123s. My '77 W123 went through two steering boxes in 155K miles with gentle, mostly highway driving. No abnormal wear on any other steering parts. I flushed the system and it now has power steering fluid along with the original steering box that was rebuilt. Power steering fluid is available everywhere and is not expensive. No need to buy the high priced stuff. Any name brand will do. I use Valvoline in both my cars.
