hey sup guys. i have this annoying sound coming from inside the bay near the crank pulley at idle. i cant figure it out but when its at start up idle youll here this hard to explain sound. So randomly one day at idle while getting ready to leave from work i turn on the ac and the noise goes away. when i turn off ac, noise comes back.

do you guys think my ac compressor is going out?
or needs to be recharged all the way?
lmk what you guys think.


here some info on the car and engine:
95 del sol si
w a 95 gsr eng and trans with p/s and ac.
i used the gsr ps pump
using my sohc ac compressor w the crv P7J ac bracket

 

loose belt, bad tensioner pulley, or bad compressor clutch.

 

the belts bend at a 45 degree angle when i tighten the tensioner. where exactly is the compressor clutch? where can i buy a replacement tensioner?

 

dang! majestic honda has just the tensioner pulley for 40. im pretty sure my local honda will sell it to me for 50 sumthing.

 

I think it's probably a bad A/C compressor clutch.

 

will ac still work if the compressor clutch is bad? cuz my ac still works, it still blows cold

 

if it is the clutch, its just a matter of time before it fails. What kind of noise? Bad clutch usually makes a rattling noise. My pulley bearing went bad. It made a "screaming seal" noise. I think I paid like $30 at oreilly for a new pulley

 

If the noise is coming from the pulley area of the compressor, it can only be the clutch or rotor pulley.

 

yeah its hard to tell what noise it made. i wanna say like a bad waterpump sound. ill see...imma go change the pulley since its cheaper than a new or rebuilt ac compressor.

 

hard for me to tell too. i put a long screw driver on the compressor body and listened to the screwdriver. also did it to the idler bracket and they sounded loud compared to the ps pump.

 

A cheap engine stethoscope would help you pinpoint the source of the noise. $4 at Harbor Freight Tools.
