    My truck has been leaking anti-freeze and i am about 99% sure it is from the water pump. My question is how much do they cost and are they hard to install or not?? Thanks in advance.

    you can usually get a remanufactured with warranty for less than $60. New one is not alot more $ usually. They are easy to install. A few things to watch for. unhook hoses. take 4 small bolts loose for pulley/belt, remove 4 9/16 bolts that hold waterpump on. scrape gasket material carefully off of block. make sure area around holes on block are clean. put silicone on bolts when reinstalling waterpump because 3 of the 4 bolts enter water jackets on the block. torque bolts. can't remember how much torque right now..can get back to you on that if needed.put the pulley,belt and hoses back on and ride and look to make sure not leaking. not hard to do at all.

    on my 74 400 it's simple, you neglected to say what it's on, and how much "technology" it has.

    I just got a winch, it takes the fun out of things.

    Yup waterpumps are cheap. I recomend getting a new one for a few dollars more (I sound like an infomercial salesman [​IMG] ). I like the Borg Warners for aftermarkets and AC Delcos. If you need a hand don't be afraid to ask.
