    Default Power Steering Pump & Hose Repair

    Another transfered article.

    Since it's such a common problem, here's my collection of three Power Steering Pump articles for the 4th Gen ST16X series (ST18X is similar).
    Enjoy

    1) PS Pump & Hose Removal (from the BGB):

    Note: Don't worry about the SST (below). A monkey wrench, regular crescent wrench or best of all, 17mm flare nut wrench work just as well.










    *Note:
    You may find it easier to remove/loosen the top bolt first because the bottom bolt will support the pump, keeping the weight and tension off the top bolt.

    A socket doesn't fit properly into that restrictive area where the PS pump top bolt lives; no clearance. I find it easier with obstruction wrenches, (like "S" or "C" shaped ones), offset box, crow's foot and/or Gear or ratcheting flex-head wrenches.




    2) Tensioning the PS Belt:
    I've always found it difficult to get enough tension on the PS belt in that cramped space.
    Try this trick: wedge the wide flat part of a screwdriver or prybar into the slot of lower mounting bracket. Apply leverage by pushing the handle towards the front of the car and the blade against the PS pump body. Tighten the bolt and you're done.



    3) Custom Built PS hose:
    Here's a tip that's not very hard to do and will save you $$ when repairing the Power Steering High Pressure Hose.

    I used a grinder and Dremel tool to remove the old crimps from my leaky OEM PS high pressure hose but retained the factory OEM fittings. Took me a little over an hour or so. Work carefully and try not to cut or grind into the original fittings. I nicked mine a few times but it was still OK.

    Took it to my friendly neighbourhood hydraulic hose shop. They crimped on new ferrules and a higher-than-spec, wire-reinforced hose for only $14, taxes in. Sure beats paying $80 for a jobber hose or $150+ for a weak, non-reinforced Toyota OEM hose.



    Here's how the fittings look disassembled below:



    The hose is double-wire braid reinforced, rated @ 4800 psi.


    Funny, the shop guy realized after he made it that it was a bit of over engineering, but it'll never leak again
    Previously, I've also used the single-wire hose that was rated @ 2600 psi - more than adequate and what I'd recommend because it has a bit more flex.

    Good work Nitro! I love the article. I never thought of making my own hoses, but now I will next time that problem arises.

    Step one, pull engine. Step two, remove PS pump. Step three, profit.
