Squealing Aircon Belt during Cold Start

**r1chm0nd** · August 10th, 2011 06:14 PM

Hi guys,

I noticed that one of my belts are squealing intermittently during cold starts. It lasts around a minute or so. I concluded

that it's triggered by the aircon because once I switched it off, the squealing sound is gone. Any inputs as to what might

be the cause of this? This happens most likely after raining, but not everytime it rains. I'm not sure if that's just a

coincidence?

sounds more like a loose belt. but if the belt is at least 4 years old, the drive surfaces are not gummy anymore and will tend to slip and slide. gates, the world's leading belts and hoses manufacturer recommends you replace your belts regardless how they look like.

The compressor or a tensioning pulley might need servicing/replacing. Or some tension adjustment on the belt.

I just replaced my aircon belt along with timing belt and alternator belt a few months ago. Around May to be exact.

How much would a tensioner pulley or compressor pulley cost?

are you using multiribbed belt or the regular v-belt? if your pulleys are multi grooved, check for foreign objects embedded in the pulley grooves preventing the belt from seating properly. these grooves can be cleaned with a pick

Can I do this on my own? I think I have to open the valve cover so I can have access to the belts am i right?

you were talking about the accessory belts. these are: drive-crankshaft pulley, compressor pulley and the tensioner/idler pulley(which hardly cause the squeal unless the bearing is shot). all these pulleys are accessible after removing tire number two and removing thee fairing from behind the tire
