"Change power steering fluid? We've never done that."

Discussion in 'General Motoring' started by Percival P. Cassidy, May 3, 2007.

  1. Looking at the recommended maintenance schedule for our '02 300M, I
    noticed that it was recommended to change the power steering fluid at
    48K miles (now past on our vehicle). The service adviser at our 5-Star
    dealership looked it up and said, "You're right: it is recommended, but
    I don't think we've ever done it on any vehicle."

    How important is that steering fluid change? Do dealerships commonly
    overlook or ignore recommended maintenance items?

    It's a good idea to do, as is flushing old fluid from brake systems.
    Not very many shops will do steering system flushes.

    I had mine done by a Tunex. I think that they charged about $59.

    I didn't flush the PS on my Chrysler LH Concord, I didn't notice a flush
    recommendation in my info and it felt OK.
    At age 10 yrs when turning full lock out of a parking space the fluid
    hose connector blew and I had to get a rebuilt rack.
    The (non Chrysler) garage which did the repair said I should have
    flushed it.

    I've seen many posts on this and other forums in which strange noises in
    the power steering were eliminated by a fluid flush. Most (all?) later
    model Chryslers should be switched over to ATF+4 (I think *all* come out
    of the factory with it now). There's a TSB that covers this subject
    (lists of which vehicles should be switched over if flushed) - a search
    of this news group will find the TSB number if not the vehicle listings.

    You can find the TSB here:

  6. Okay, so how does one flush the PS system? The only thing I could
    think is to disconnect the return to the pump, and drain it into a
    bucket... run the engine to pump the rest out, and then fill with
    new.... flush again.......

    I would advise not to go to that site. The TSB's are bogus - they list
    TSB's for things like '95 300M, '96 300M, '97 300M, '98 300M.

    There was no 300M made in any of those years. The late model 300M was
    not in production until '98 ('99 MY). Plus there is no information on
    the TSB's other than title.

    IOW - the information on that site is worthless from at least two
    points. Makes me suspicious that that site may have malicious code.

    There's nothing bogus about the site at all.
    I built the site and the TSB data comes from databases provided by
    NHTSA .

    There are some anomalies in the data, as you point out above.
    No one with a 1995 300M is going to be searching for a TSB on a 1995
    300M because that car does not exist.
    But someone with a 2001 300M will find the most recent TSBs on their

    As I say, the data comes right from the National Highway Traffic
    Safety Administration.

    I disagree. I see a list of TSB's. I do not see the TSB's themselves -
    unless I missed something.

    For example - here's one item in the list:
    "2000 CHRYSLER 300M
    NHTSA* TSB Technical Service Bulletin Number: 621898 Bulletin Date:


    It includes a link to the NHTSA site.

    That is not a TSB. It is a TSB title and brief subject. Again - that
    does not a TSB make - at all.

    There were a number of TSBs issued, here is the gist of the latest one:

    Between 1998 and 2002, the second generation LH cars were factory filled with
    one of three fluids for power steering. The earlier fluid was the traditional
    Chrysler fluid that had been used for years. It is *not* compatible with
    ATF+4. By 1999-2000, cars were getting an intermediate fluid that *is*
    compatible with ATF+4. By 2004 +/-, ATF+4 was the factory fill power steering
    fluid and is preferred. I don't think the intermediate fluid is available

    The catch is that you cannot add ATF+4 to a vehicle with the oldest fluid, a
    complete flush would have be performed. I think I've posted the relevant TSB
    here in the past.

    I'm not sure what to do with my own car, a 1999 LH. It was factory filled
    with the intermediate fluid and should have been changed to the ATF+4 fluid.
    Unfortunatlely, according to my dealer receipt, it was replaced with the older
    fluid(!) That means I cannot just do a regular fluid change to ATF+4. I
    didn't catch this until much later, I had just assumed the dealer would use
    the right fluid for my model year.
