Bad water pump

Discussion in 'General Motoring' started by SteadiSteve, Dec 31, 2003.

  1. No need to assume "stupidity" here.:) We've all gotten cornered with a
    job at one time or another - the first time I did a TB, I took everything
    else apart before I found I couldn't get the pulley bolt out... had the car
    out of action for 2 weeks figuring how to attack it. On the advice of a
    mechanic, I eventually jammed a big screwdriver in the ring gear but it
    scared the sh*t out of me applying all that torque against it.

    Honda started putting the 50mm hex socket in the pulley ~'91-'92 - my '90
    Civic didn't have it, my '92 Integra does. You might want to check the
    next time you're looking there to see if yours has it. The Schley tool
    which fits it can be bought here:
    http://www.autotoolexpress.com/honachardamp.html Snap-On has a similar
    thing:

    Another little burp: the 2nd time I did the job, to get at the water pump,
    you have to take the inner plastic shield off and it's held on with bolts
    in recessed holes in the plastic. My 3/8" drive 10mm socket was to big to
    go in the hole - you need either a 10mm "thin-wall" socket or a 1/4 drive
    10mm socket.

    Good luck when you tackle the job.

  2. Harbor Freight has a very inexpensive torque wrench too. I just bought one
    of these when I did the timing belt and water pump on an 85 CRX. I used the
    low tech approach on the crankshaft pulley. Just inserted a spanner wrench
    in the holes and placed it on a 6 by 12 piece of lumber to hold it in place
    and then used a 3/4" socket adaptor with a 3 foot long breaker bar. Good
    luck wolf.

    I've NEVER pounded on a crankshaft bolt (and do not recommend ever
    doing so) with an air hammer. Honda probably recommends against using
    an impact wrench on the crankbolt because the impact wrench can put
    out far more torque than the bolt should ever be tightened to.
    However, its fine for removal of the bolt and I've been driving around
    on an impact wrench (with the aid of a 120 ft-lb torque stick)
    tightened crank bolt for nearly a year with no problems.

    But that lug nut was fun. And that was just a practice one..

    To get it off, I agree. Whatever it takes. But when putting it back on,
    no. the Helms manual for the '96 Odyssey on page 6-7 says: "Note: Do not
    use an impact wrench when installing"; and again on page 6-8: "... 181
    lbf-ft. Do not use an impact wrench when installing."

    I don't remember where I heard that explanation, or if it is the correct
    reason, but if I am doing it to my own car, I am not going to ignore the
    manufacturers warnings.

    For somethng as critical as tightening a crank pulley bolt, definitely not.
    Ever seen what happens when one of those things comes off? You're stranded
    at the very least. Use a torque wrench.

    But you can't damage the oil seals or bearings by using an air wrench or
    hammer to take the bolt OFF, which is the subject in question here. The
    caution has to do with overtorquing.
