Cool, you will definitely need the impact set for many future things.

cpomakita.com has refurbed makita corded and cordless impact wrenches (as well as all kinds of cool tools) for cheap. Just an FYI for those out there that are shying away from projects requiring heavy tools. Thanks for the input mengsta.

On a side note, the torque specs for the crank pulley per the "2006 Scion tC Repair Manual (RM1104U)" under 14-18/Engine Mechanical diagram is 133 ft*lbs. I've seen 110 and 150 mentioned and found that in the diagram while doing my homework for the mod.

Did this today. Took about an hour with the marjority of the time getting the belt back in place because it slipped out. Had the impact wrench do the heavy loosening. The belt was off a little bit on the water pulley and had the tension bolt locked out tight, so I put the transmission in neutral and used my breaker bar to turn the crank by hand to thread the belt back on the pulley. Thanks for the how to and all the additional input folks!

I am removing my crank pulley. The car is in gear but the crank is still spinning when I try to loosen the bolt. The car is automatic. How do I keep the crank from spinning?

Inertia, aka use an air ratchet.

This is incorrect. The destroyed bearings in my old block can attest to this.

I am pretty sure you have to use an impact gun or you will never be able to get it off

thank you for the write up Q for the mods can this posting also be labeled for belt change outs?
As this weekend I could not find a way to release tension on the belt until I read this how to

how come i can only find faqs about crank pulley alone, are the other ones just not sold? cuz i have a feeling changing them all lightweight would do that much more

what if i went smaller or bigger in order to replace all pulleys with lightweight and just got a new belt, could that benefit also?
