    I had to do that on my 1989 3.0 minivan.

    First, you will need to get the water pump, PLUS the tubing and "O" rings
    from a dealership, because the parts houses do not have the entire pump
    assembly, and do not carry the tubing. The timing belt can be bought at a
    parts house, though. You can access the timing belt and water pump through
    the passenger side wheel well, but in order to get the timing belt cover
    off, you will need to remove the compressor, the pulleys, and the power
    steering pump. Removing the passenger side motor mount would also be much
    helpful, so you can manipulate the engine to get the bracket cover off.
    Then remove the timing belt covers. Then go to the top of the engine and
    remove the intake plenum (sp) and intake manifold, in the steps outlined in
    your Haynes repair manual. This will give you access to the rest of the
    water pump assembly tubing, and "O" rings. The timing belt is what drives
    the water pump, so replace the pump assembly first. Make sure that you
    dress the "O" rings before trying to replace them into the water pump, or
    they will slip out of place, and you will waste your time putting things
    back together, only to find you have a major coolant leak when you go to
    refill the coolant.

    Of course, you will have had to make sure all the timing marks are lined
    perfectly before replacing the belt. They are not hard to see, and can be
    adjusted easily.

    BTW, while I was in there replacing the water pump assembly and timing belt,
    I went ahead and replaced the front main seal, behind the harmonic balancer,
    even though it was not leaking. I replaced it because I did not want to
    fool with it when it did fail, and I already had instant access to it. Just
    FYI.

    I did this job by myself over one weekend, but it is a lot of work.

    That is it in a nutshell. I hope this helps. I have part numbers and such
    if you want them, from the dealership, so you can ask for the right parts
    right off the bat.

    Aftermarket pumps indeed are generally sold as only half a pump. You
    have to save the back half of what you remove from the vehicle and put
    it together with what you buy from the store. This is no big deal.

    I would say that removing the motor mount is necessary rather than
    helpful.

    The tube goes under the intake toward the transmission. You can access
    this tube from the transmission side without removing anything from the
    top of the engine. Just take the hoses off and remove the bolts that go
    through the mounting bracket into the bell housing, then pull the tube
    out from under the air intake.

    This can be frustrating. I have found that when you turn the engine and
    tighten the belt, you will be able to see if the marks all line up at
    the same time. If one of them is off, you can turn the crank backwards
    and the belt will jump one tooth at a time on one of the pulleys. This
    is very helpful. Once you figure this out, you can set the other two
    pulleys to match each other, then turn it back and forth until the third
    one comes into line.
