Default Serpentine belt pulley question

Does anyone know what size socket in need for the bottom serpentine belt pully? I could not get a clear enough look at it yesterday, and need to pick one up today so I can remove it. Thanks!!!

WHICH PULLY? crank? water pump? alternator? power steering pump? belt tensioner? air cond. compressor?

belt tensioner is 13mm to mount and 15mm on the pully

You don't want to be foolin' with the big one on the bottom unless you really need to. Pix of some ideas, plus the old breaker bar leaned against the pavement and bump the starter.

The chirp is coming from the pulley I have an arrow drawn to. I'm guessing it's the crank pulley. Does anyone know any secrets about getting it to stop with out removing and cleaning or replacing? Thanks!!!

when is the last time you replaced the belt? and did you use a good one or super cheapo, also be sure the belt is routed correct as in the pic

The harmonic balancer crank pulley does not have small bearings like the others, it is supported by the crankshaft bearings and they most likely are not squeaking. You may want to slip off th belt and turn everything else looking for rough spots. Or poke one end of a yard stick against things, like the pulley bracket, and your ear against the flat side of th other end of the yard stick.

The belt is routed right, I changed it about a month ago. I put a good yr on which stopped the chirp for about a month, and now its back doing the same thing as before. Ill pull the belt today, and get the stethascope out.

Should the power steering pulley spin freely? Mine gets about 1/4 a rotation before hanging up? If this is the case I guess I will be changing the pump out unless there are any other ideas.
