A chirp type noise may be noted from the serpentine belt when the steering wheel is at full lock with the engine idling. Our technicians tell us a revised serpentine belt tensioner is available to correct this concern.

    This chirping has been a problem since we bought the vehicle new. Last year all the pulleys were replaced along with the serpentine belt only to have it start chirping within a month or so. Had the belt replaced in Dec 2013 and it is chirping already, Feb 2, 2014. This is a minor inconvenience in that I could not be happier with this vehicle and it has served my family well.

    Chirp was miner for 30 to 40 days. I thought it was a pulley on the A/C compressor, which was replaced 8 months ago, or the power stering unit. Just a constant tic tic at idle. It got louder, especially 2000 RPM and up. It got so loud it was embarrassing to drive, but I still thought it had to be a pulley. With a spray bottle I sprayed the ribbed side of the serpentine belt (engine running) with water, the screech even got louder. I read that rubbing a bar of soap on the ribbed side of the belt carefully (while the engine was running) may help, or stop it completely. I put a bar of bath( soap in the jaws of a medium sized pair of Chanel locks and gently pressed the soap against the ribbed side of the belt (engine running) for about 15 seconds, and it worked. Not a single squeak. My wife drove about 60 miles, got home and not a peep. We both are very pleased. Letts hope it lasts. The belt has less than 4000 miles on it. so my concern is what causes this, and do I need to do this proceedure every so many miles?
