    Default Power steering fluid

    Hi guys

    My 2011 Hyundai Santa Fe power steering fluid level has dropped to the minimum level. Not sure how long its been at that level but presumably when it was serviced a few months back they would would have checked all fluids and topped up if necessary.

    I admit I do not look under the hood often, and have not noticed the fluid level drop before.

    Any Idea what fluid Hyundai uses. Should I be looking to flush the system and replace with fresh fluid? The fluid looks pretty dark through the reservoir.

    Should I be concerned that that the fluid level is down to the minimum level, I cannot see any leaks or spots on the floor.

    Appreciate all advice.

    Thanks

    I spoke to a mechanic at Hyundai and he suggested a flush. He also said that they use an expensive fluid but a good AFT made by Castrol should be fine.

    What do you guys think? I am a little nervous with his advice.

    Rather buy the Hyundai stuff at the dealer, then take it to any decent workshop and let them drain the old stuff and do the flush with ATF and then drain and put in the Hyundai steering fluid.

    I've seen cases where ATF doesn't work well with old seals and then you have a leak.

    This baffles me. I sent my Sorento for a service. One item is "top up fluids"... Why should fluids be topped up in a closed system. If fluid disappears then it must be leaking = problem right?

    Some systems like hydraulics ''sweat'' and degrade and over time, lowers fluid levels.

    yep, volatile components evaporate under pressure and heat

    Thanks for the reply.

    I complex is the job? I am fairly handy around the car and tend try to do what I can to save a buck.

    If not a complex process I would like to attempt myself.

    How much fluid is required (I suppose Hyundai can confirm) and I would still need to flush with ATF? How much ATF would the flush require?

    I agree, the invoice after a service always states all fluids were topped up, although I have never confirmed this myself.
    In my 8 years of owning the vehicles they have never advised that the power steering fluid should be flushed.
