Crank pulley bolt removal

[GPmanter]

I know it may sound like an idiot question but I'm at a loss. Trying to remove the crank pulley on my dads 06 Grand Prix and the bolt won't budge. Tried an impact but no luck. Any suggestions?

Stronger impact or use a breaker bar with a long pipe on it.

You'll have to wedge a pry bar or something into the flex plate teeth to stop it from spinning.

Not an idiot question, these things put up quite a fight. Lock the flexplate with a vicegrip and pull on the crank bolt with a 4 foot breaker bar. Should do the trick.

Once you get the bolt out be sure you have the proper bolts/remover for the balancer so you don't damage it. Also, once you go to reinstall the balancer be sure you line up the woodruff key and shove the balancer on by hand to be sure it's correct before you run the bolt back in or you could screw up the key slot in the crankshaft. It happens more than you would think so just a heads up.

breaker bar and the starter, google redneck crank bolt removal.

I thought of trying that but since the car will continue to crank for so many seconds after releasing the key I wasn't too sure about that method

It'll work I have done it on my 05', just turn the key off after it pops loose.

Thanks for the suggestion guys. I bought a new impact and didn't make a lick of difference so I used the redneck method and stopped when I heard it snap loose. Now to buy the bolts for the puller. I had some at one time but my garage is a nightmare. They are probably hiding with my 13mm deepwell. I will go to lowes and get the 1/4" bolts to remove the pulley. Then I can finish this blasted timing cover

They are usually 1/4-28 fine thread.

Also,

Make sure to use hardened bolts. Grade 8 if possible. Grand 5 is better than nothing, but can still break.

Yup that's what I was thinking as well.

fyi, they are not 1/4 inch thread bolts. its metric, and you dont need hardened bolts. bolts are listed here, get some washer cause the heads will be to small and can pull through the puller http://www.grandprixforums.net/threa...a-crank-sensor

Thanks for everyone's help! from breaking the bolt loose with the engine, to the tutorial that showed the crank pulley removal I've got the pulley off the car. I may not have my Grand Prix any longer but am glad I am able to get help when I work on my Dad's car.
