SOURCE: change idler pulley

It's a T-40 size, but I removed the bolt by first removing the bracket holding the pulley--I assume you're talking about the alternator idler pulley, the one right below the alternator. The bracket is held in place by three 14 mm bolts which I was able to reach from the top of the engine (after removing the black plastic air tube). I then put the bracket in a vise and "buzzed" off the 14 mm nut using an electric impact wrench ($30 +/- from Heartland of America). Be careful when putting the nut back on--the impact wrench will likely be too much torque!

SOURCE: what size bolt for a 1999 cavalier idler pulley

The proper way to do this since you do obviously need one is to go to O'reilly's or autozone or any auto parts store and buy one. They will tell you what to buy and even will tell you over the phone.

Does anyone know the exact torque spec for a 2014 Scion TC crank pulley bolt? It's the 2arfe engine if that helps.

Torque has to do with the size of the bolt and the thread per inch as well as the thread pitch and is not specific to any vehicle .Its got to do with bolt and the nut .
And seeing you want the crank pulley also known as the harmonic balancer spins in the direction that would tighten the bolt the finer the thread and larger bolt and the harder the metal the more torque it will handle but your in the range of 50 to 60 ft lbs if your worried get some blue loctite don't use red it will never come off with out a torch again .
It will tighten because of the direction the engine spins

Need to replace the idle pulley on a ford f250

if it is a 7.3 or 6.0 turbo diesel it will have a duallie tensioner-pulley setup. use a half inch breaker bar or ratchet to grab a hold of the tensioner then turn it very firmly counter clockwise until you can remove the belt. after that use the corresponding size socket and ratchet to loosen the bolt that retains the idler pulley.

High pitch noise coming from under the hood louder when I push on the gas pedal

This could be a couple of things. There are bearings in the a/c compressor, alternator and p/s pump. One of these could be going out. There is also a bearing in the belt tensioner and in any idler pulleys connected to that belt setup. Check those first. If that's not it maybe check your fan. There is also a bearing in there.... If it's an electric fan disreguard that part. If it's belt driven see if it spins with the engine off, we don't want to loose any fingers. If the fan clutch is seized up that's an easy fix.
