    It's time to change the timing belt in my '98 Impreza [2.2L]. What's the
    easiest way to get the crankshaft pully bolt out without using a strap or
    chain wrench? [I don't have one] It doesn't have the clearance to get an
    impact gun on it unless I take off the radiator and condenser. I tried to
    loosen the bolt with the transaxle in gear and e-break on but the pulley
    turned with the socket. This is my first timing belt change so any insight
    would be helpful.

  2. Hi,

    This subject comes up frequently, so a google on "timing belt" in this
    NG should lead you to some of the hints. Some are aimed at manual
    gearboxes, some at autos, so your car should be covered.

    Good luck,

    I used an appropriate socket on a breaker bar braced against an
    immoveable part of the right side of the engine compartment. I had a
    friend crank the engine for a split second....spun the bolt right off.
    This sounds scary, and it is, but I've been doing it this way for 20
    years as a mechanic and owner and have never had a problem with it.
    You DO need to be very sure which way the engine turns and put the bar
    in an appropriate position. For a little additional safety, slide a
    4-5 foot pipe over the breaker bar. Good luck

    I recall some serviceman hit his head with such breaker bar extended with
    ~2m pipe, also starter on my old Passat Syncro was broken when they cranked
    the engine... Unfortunately I noticed starter problem later.
    Needless to say, I never went back to that service again.

    I did the timing belt for this particular model, I removed the
    radiator (very easy) and let the AC-radiator in place. I then had
    enough space to use an impact gun, but not eough space to use it
    staight. I took an impact universal joint extension, that way I could
    use the imp. wrench in a 35 degree upwards angle. Worked well, the nut
    came loose in 3 seconds.

    On a manual venicle simply put in in 4th gear.

    On an auto, remove the cover from the LHS of the transmission cover near the
    intake manifold. This gives access to the flywheel which has slots cut in it.
    Hold the flywheel with a large screwdriver or bar. Use a long bar on the
    socket for the pulley nut & away you go.
