Greetings,

I have a noisy pulley on my 2007 Yaris Hatchback and was told I need to replace my AC Compressor and all that. Another shop made it seem like they would only fix the pulley. Is it possible/practical to replace just the pulley if the AC system is working fine?

Thanks

I expect that it is possible to replace just the pulley. To be honest, I haven't looked at my A/C system closely enough to know if there would be room to attach a puller. I would be surprised if the job could not be done with the compressor on the car. That would be easiest as there would be no need to have to recharge the system.

What is noisy? The A/C pulley? Or the A/C clutch?

Not an easy job to pull the pulley off. This is what the end of our compressor looks like. There are several threads on here which question how to go about trying to get that little buried nut out of there. Space within to work is very confining.

as with what WeeYari stated, I haven't heard of anyone successfully removing just the pulley.

Most tend to just go with an ebay reman'd compressor which are typically around $100. I haven't heard any of the ebay unit blowing up and I currently installed one when I did my engine swap and have had no a/c issues.

Wow, that does look tight. You'd almost need a thin-walled socket. And, then would it withstand the rigor of removing a rusted in bolt. It does sound like a reman compressor would be a better option if one had to replace the pulley.

Belts can squeal. How can a pulley be noisy?

It's a clutch pulley. They can definitely make a lot of noise when they are failing. It was fairly common practice to replace these on the Dodge minivans.

9mm 1/4" drive fits. I suspect you need some type of spanner to hold the pulley assembly stationary while working the socket.

When I talk about working within confines, I'm referring to attempting pulley removal with the compressor still mounted. It should also be noted that the clutch is internal. That outer disk on the pulley that looks like a clutch is not.

Ah, I see. The pulley is solid then. I stand suitably corrected. Much to learn about these fine autos. Thanks.
