ac pulley clutch bearing

[v6mOtOrhEAdftOp]

Ok so I can hear a loud clankign noise coming from the pulley system when I start my car. I'm 99.9% sure it's coming from the ac pulley since it starts and stops after something engages (sounds just like shifting). Do I need to just get a new pulley or is there more to this? Also, I need to know the baest place to get one (any place but the stealership)

Re: ac pulley clutch bearing

Before you go blaming the A/C compressor bearing, take the belt off and have a good look at more of the items in the belt rotation group, such as:

1) Belt tensioner assembly for a worn or damaged piviot arm bushing.
2) Idler pullies for seizing and/or wear.
3) Alternator bearings.
4) Harmonic Balancer pully isolation rubber degradation or seperation (Failsafe lug contact)

Anyone of these items can start to make the noise that you described when the A/C is selected on and the compressor pulses are imparted into the belt group.

Ok thanks, there are a few items I didn't check their (meaning alt bearings). I can tell you for sure, it has to be somethign with bearings and/or clutch for the fact it disengages.

take off the belt and spin each pulley, see which one makes noise or doesnt feel right

Re: ac pulley clutch bearing

ok so more news, I just looked at it and I think I may be correct and have to replace the whole pulley. The clanking sound starts up again after I turn the ac off and then when I turn it back on, it stops after about 2-3 seconds (the noise stops that is).

Another update:

I replaced the ac pulley and it fixed the pinging. I decided to look furthur into my car and noticed my coolant was getting kinda old, so I replaced that. Now the only thing left is royal purple ATF, royal purple oil, and replace brake fluid

Mines bad too, it makes a squeaking sound. I just keep the climate control on vent and theres no noise only at startup for like 5 seconds.
