how do people get the pulley crank bolt loose without impact gun..???
mine is NOT even thinking of coming loose.. I have a 2.6cf at 90 psi compressor..
what is the smallest impact gun I could get that would break and install that bolt..??

1/2" impact gun

I read a trick on the internet (it may have even been in this forum) that I used to get mine loose. It's pure ghetto garage and if you try it don't hold me responsible if you break something.

* I jacked the car up a bit, removed everything needed to get at the bolt.
* I placed a cinder block under the car and directly underneath the pulley.
* Grabbed a breaker bar (about 16" - 18") and used a socket made for air impact tools.
* Placed the socket on the head of the bolt so that the handle of the breaker bar went into one of the holes in the cinder block.
* I wedged another cinder block against the first one for a little extra insurance.
* Put the key in the ignition and cranked the engine for a split second (gotta crank it and turn the key all the way off in one swift motion) heard a loud BANG (the breaker bar hitting the cinder block) and the bolt was loose.

Didn't damage anything in the process.

realized that the water pump is Under the shiny wheel that I was calling the tensioner wheel. It has 3 small bolts and shouldnt be hard to break those.
What SUCKS is I almost did serious damage by trying to get the fkn crank pulley
off. It doesnt need to come off for a water pump change. I need to replace the wp
just to get down the road to the dealer. I wouldnt never mess with pulling the whole front off of this little pain in the ass.

Impact wrench is the only way to do it easily. Trying to jam the pulley can easily crack the aluminum parts you'd be bracing it against.

Already went through a water pump?

nothing better than an impact. but, if you got no impact, leave the belts on it and put a breaker bar on there, smack it with a hammer. or, you can always try to lock the pulley down and take a chance of bending the old pulley...i'm assuming you got a new one...

07 Hatch 171K manual
actually my water pump looked perfect, but I already have a new one coming. I'll
put it in... my problem is definitely the cam timing gear. If I could I would get a mechanic to
install a regular non geared cam sprocket and do away with the entire VVTI system.
But I probably couldnt find the right fit, unless someone knows how to do this???
by the way... my AC compressor pulley bearing is bad... I dont need AC so am going to install a smaller belt and bypass the AC. Anyone know the exact size of a smaller belt for that???
otherwise I will measure with a string......

No need to measure - The Toyota part number is: 90916-02499 for the shorter one. You can also get a non-OEM one by having your auto parts store look up the one for a Yaris without AC.

A 1/2" ratchet with a 20" extension got mine off immediately. Didn't even really need any additional leverage. I also put a crowbar in the spokes of the pulley to hold it in place.

You could "rent" these by going to home depot / sears hardware / lowes, buying them, using them, then returning. I didn't see much use for a 1/2" ratchet, so I was quite thrilled to have gotten the install done without paying any additional money.
