Loud screech at startup
Hey Everyone, I have a 2005 RX330 AWD. Every so often when I first start up the RX, there will be loud screeching sound immediately upon start up. Any clues as to what it might be? It's not particularly cold in Seattle vs. Chicago where I used to live. And it happened when it was warmer out too. I will prolly hit 5,000 miles in a couple weeks, so I'll take it in then.
Just wondering if anyone else experiences/experienced this?

The drive belt? Belt tensioner pulley?

There should be 2 belts on the 3MZ-FE V6. A power steering pump belt and an alternator/ A/C compressor belt. Its likely the Alternator/AC Belt (The largest of the 2) is slipping. Have a tech look into it.
