'94 SL2 PS bypass?

    - I'm hoping someone here can give some advice on this one -- my '94
    SL2 has a PS pump that is going out; from the looks of things the
    pulley can be completely bypassed without affecting the belt
    tensioner? I do have AC. Can anyone who has tried this tell me what
    length the belt should be? Unfortunately not a lot of extra time or $
    $ to replace the pump right now.

    thanks -

    I'm not much of a saturn man but i would venture that you could remove the
    pulley or entire unit and measure your new distance sans pump and buy a belt
    that fit. You can buy belts in increments. You'll have to be sure your new
    belt still routes properly and all pulleys are driven the correct way.

    This is a band-aid until you can get the pump. I have never worked on a
    saturn, your model may need the pulley there to route properly.

    I suppose you could also just pull the hoses, cap the outputs on the pump
    and fill it back with fluid (just to lubricate so it doesn't sieze) and not
    mess with the belt routing.

    When you say the pump is going out, do you mean it's about to sieze or its
    losing its ability to generate pressure?

    I have permanently removed the power steering pump on my '92 SC during its
    transformation into a track-only car.

    I would STRONGLY recommend against doing this on a street-driven vehicle.
    Some Saturns came with manual steering from the factory and had a different
    steering rack (plain SL and SW models, I believe). But if you bypass the
    pulley on a car that came with a power steering rack, your stationary pump
    then becomes a restriction. As you turn the steering wheel, I'd imagine the
    rack is trying to push the fluid which will not want to easily go through a
    pump that is not running. When I removed my pump, I put a resorvoir tank in
    its place which allows the fluid to flow freely when turning the wheel.

    If using the steering rack in this way that was meant to be assisted by the
    pump, parallel parking becomes extremely difficult. Unless the car is
    rolling at least 10 mph, it takes a huge amount of effort to turn the wheel.
    How much? Turn your key on but leave the car off. While your car is
    standing still, attempt to turn the wheel lock-to-lock. That's what it will
    feel like all of the time below 10 mph or whenever you try to do any
    low-speed parking.

    In addition, when I removed my pump I had to swap the idler pulley from a
    smooth model to one that had grooves as the belt was now routed differently
    and the opposite side now traveled over the idler. But I removed my AC
    compressor at the same time. I'm not sure if any Saturns over the years
    came without a power steering pump but with air conditioning. If they did,
    you'd need to find a belt routing diagram from one, get that size belt, and
    determine if your current idler pulley will do the job.

    You can find a replacement pump on eBay very cheaply, probably less than $30
    or so. You would save a lot of trouble by just replacing the pump. Good
