Hey all,

Can somebody please let me know the proper power steering fluid for a 97 S600? I thinks I have seen 3 or 4 different types listed for this car, some synthetic some non-sysnthetic. Can I add synthetic if I have non-synthetic?

Thanks,

To be safe I'd just go to the dealer and get a bottle. The P/S reservoir only holds 1/4 quart or less, so cost isn't really a big part of it.

Have you flushed out the steering or replaced the filter lately? Always good to do that.

The answer is NO, mixing will contaminate the system, and generally damages parts.

Thanks whunter for your reply, very good info but I don't suppose this procedure applies to a 97 V12, right?

I assume you have an S600 (Coupe), chassis: W140.076, Years:1994-1997, Engine: M120

Answer:

No.
Yours has a screen/filter inside the power steering pump tank, and is not a regular maintenence item.

Filter, power steering
MB# 000 466 19 04
$110.00

tank seal ring
MB# 022 997 19 48
$1.40

Mine is sedan (140.057 I think) with M120. So I'm guessing I shouldn't worry about flushing/filter for PS. Thanks.
