Stupid %#@*! crank pulley bolt

Ok, I'm trying to do a timing belt on my car (99 Chrysler Cirrus with a Mitsubishi 2.5L V6) and I cannot get the bolt loose. There seems to be no way (with the tools I have) to get the thing to turn or even put any pressure on it without it trying to turn. I am looking at either renting an electric impact (No air compressor) or buying a chain wrench but I am open to other ideas if anyone has any. The impact is $12/day to rent so I'll try that first and the chain wrench is $100 from the Cornwell truck (only place that has one big enough) so that's my second idea. Any other suggestions?

What have you used to try to stop the pulley from turning? Usually there is a way to stick a large screw driver through a hole in the pulley so that it will wedge itself against the block and stop the pulley from turning.

I'm guessing you don't have access to a large air compressor.Remove the starter and if there is room take a large prybar and wedge it in the flywheel teeth.You will have to have somebody hold this VERY TIGHTLY.You don't want to break off any teeth.Highly unlikely but you know Murphy's law.Your gonna need a long breaker bar and probably a length of pipe to slip over it for leverage.I'm not sure how the Cirrus is setup engine wise but this will work if you have room.Another method is to get a large breaker bar and put the socket on the bar and install it on the balancer bolt.Then wedge the breaker bar against the ground.Then bump the engine over.Now this only works providing the rotation is correct AND the car is not in gear.You didn't say weather the car was auto. or manual.Just use your noodle before doing any of this.Alot of people get hurt not using the right tools or thier brains.If i'm not mistaken that balancer also needs pulled .It's not a slip on like a Honda Civic.Don't lose the key for the balancer once you pull it.Hope this helps.

I have tried to wedge a screwdriver in the pulley as illustrated in the Haynes manual but there is nothing to wedge it against. I hadn't thought of wedging the starter but that may be a possibility but that may work if I can get a decent size screwdriver in there (never looked at where it's at before). Stupid front wheel drive cars make things a lot harder than on my TJ! I mean, I actually had to jack the car up to work on it! Seriously, though, the balancer needs to be pulled as well and I do have the puller for it. Thanks for the ideas and keep them coming. Oh and to clarify, yes, so I can loosen the bolt without the engine moving.

Forget the screwdriver.You need a prybar.It will work.I've done it.Just not on a Cirrus.All the same principal if you can get in there.I had to take off my honda civic's the same way.That son of a gun is on there about 350 ft lbs. and i was to lazy to buy the tool.I had to use half of a floor jack handle on a breaker bar to break it loose while my father wedged the flywheel.Or get a POWER BAR HAND IMPACT WRENCH.Just google it you'll see what i mean.I've used those too.That'a about all i got.

Got a Dewalt electric impact gun from the local rental place and it worked like a charm. I looked up that power barimpact wrench and by looking at it I can't seem it figure out how it works?

Hey cool.With the power bar you just snap the socket on the square like a ratchet .It's hinged.You try to roughly have ithe pieces at a 90 degree angle to each other and smack it with a hammer.It basically mulitplies the torque with the hinge effect.If you had it in your hand you would figure it out easy.Well glad to see you got it off.

Sounds like a cool idea, I'm hoping to get an air compressor when I get some bills paid off though. Then I can have all the cool toys
Progress report: this car sucks! Got the new water pump and timing belt on and now I need a "Special tool" to tension the timing belt. A tool which no one else has. Nice. The battle continues tomorrow...
