Engine Squeal When Aircon Starting

[sharks]

I have an 08 d22. Occasionally (around once a week) I here a loud screeching when I flick the aircon on. This goes away in a matter of seconds. Any ideas?

Welcome to the forum, I've moved the post into its own thread to make it easier for people to find the answer when searching.

I'd guess belt first too. Try checking the belt tension, and/or applying dri-lube to the belt.

It could be the compressor, or something wrong in the receiver/dryer. Always explore the cheap options first!

Tension/change belt to start.

08 is getting on 5 years old now, I'd just replace all the belts, they're not too expensive...

Hi. I get the squeal intermittently with aircond on. There are no specific conditions when it happens - under load etc. It is the belt running on the stopped compressor pulley. The pulley stops turning intermittently. The belts are all new and tight. I don't think it is a result of lose belts, which is the common remedy. Where exactly did you spray the oil? Did you actually 'spray' oil, or just such as WD40?

Sounds like a dry bearing -the squealing and intermittent seizing. Will wreck ur belt very quickly. The AC compressor is not turning when off.
