Question about Heating & Cooling

I have a 2000 Ford Focus and the A/C compressor pulley is making a scraping noise when he A/C is turned off. The noise stops when the compressor is turned on. When the A/C is off the pulley makes erratic turns.

    Should the pulley be rotating freely while the A/C is not running?

Hi,

if the noise goes away when you turn on the a/c then you either have a bad a/c belt or more likely a problem with the a/c pulley. The pulley and/or clutch may be failing and need to be replaced. Is this something you are planning on fixing yourself?

If you want to get it fixed from a tech, if it is the a/c compressor it can cost as much as $1000 to fix. If it is just a belt it should only be around $75.

If you do not want to get if fixed right now, only option would be to leave the a/c on while driving it until you get it fixed or remove the belt. I would advise to do this as soon as possible to keep anything from breaking.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    The bearing that carries the A/C pulley can act that way. Remove the
    belt and spring the pulley by hand and you should be able to feel the
    roughness.

    Might be a case that Due to Vibration, you might be hearing a noise but when it's running, it's in motion, so you might not hear any noise.

    Thanks.

    DO ACCEPT THE SOLUTION IF 100% SATISFIED!!

The pulley will have to be lubricated on the bearings, or you will have to get gear puller and pull of the pulley and replace

My 2000 Ford focus was making a grinding noise when driving the power stering went out and I look under the hood and the belt was loose what do I do... O battery light is now on.


sounds like your belt broke. replace with a new belt. battery light is on because the belt is not spinning the alternator. If it busted you should be able to pull it right out. Make sure to check the tensioner pulley, alternator pulley, power steering pump pulley and ac compressor pulley for free play(if you can make it spin with your hand it's good) and make sure that they're not binding or making any grinding noises. If the belt has never been replaced, then most likely it gave out.

Grating noise from engine compartment then belt thrown off. Is this the water pump?


I would check a few things before saying its the water pump.I would check the idler pulley and the belt tension er and all the other pulleys on the alternator and power steering pump to see if they wobble or grind because of worn bushings or bearings.Then while you have the belt off free spin the water pump and listen for any noises and wiggle the shaft to check for any movement.If it wobbles and scrapes it would have to be replaced.

2000 Chevy Cavalier making a noise when air is shut off


This problem sounds like the aircompressor pully, the bearing is shot.
With the engine running and the air conditioner off there is a grinding noise, look at the compressor pully, does it wobble? Then turn on the air conditioner and the noise stops, look at the compressor pully again, the wobble stops? If so that's the problem.

If freon was added because of a leak, it could have leaked down again. If freon levels are too low, the compressor will not switch on. Check to see if the center (it is connected to the compressor shaft) of the compressor pulley is turning.
