    OK, another one of my noobish questions. What do you guys use to hold the engine from turning while removing the flexplate?

    there's a special tool you can get that hooks on to your flexplate to hold it while you loosen or tighten the bolts. i don't remember what it's called exactly.

    I use an impact wrench to remove the bolts.

    i stuck a BIG flat screw drive into the starter and wedged it, but an impact would be your best bet.

    I'm pretty sure that the tool that you're refering to is called a Spanner Wrench.
    I don't have one of those, nor do I have an impact gun, instead I usually just put a 1/2 drive extension through one of the holes that's in the flexplate and wedge it against the oilpan to help me crack loose the bolts.
    I do the same when reenstalling them too.
    The same trick works for me when I'm tightening the 3 Torque Converter bolts (which attach to the flexplate /forums/images/graemlins/wink.gif
    Hope this gives you some ideas.

    that's what that thing is called. i've also done it the way your talking about and also the screwdriver trick. the times i have messed with flexplate removal and installation i've mostly just wedged it with a screwdriver.

    You can bend the flesplate by doing that method(sticking a srew driver in one of the holes. Best bet is to go buy the correct tool. You will use it more that once.

    Okay, using an impact gun connected to the crank is not recommended. There is a risk of deforming your soft bearings from the reciprocating vibrations of the impact gun. /forums/images/graemlins/usaflag.gif /forums/images/graemlins/burb.gif /forums/images/graemlins/usaflag.gif

    Sample, check with AutoZone or Checker, see if you can rent that tool.
