A couple of days ago I posted the problem of a intermitent metalic chirp on my 2007 V6 when idling/running. Just wanted to share with you my experience in fixing it since it might help someone down the road. Well, becoming very concerned about maybe something major going wrong made me go to the dealer. The service writer actually heard the noise at check in when he turned on the A/C when the car was idling. Seems that using the AC made the noise happen- most like since now there was an additional load on the belt. He suspected a serpentine belt issue. So it was turned over to the tech. I managed to introduce myself to the tech and filled him in on the situation. Lucky for me he turned out to be very experienced and competent. Initially he tried to apply silicone and other liquids to the belt, thinking that the belt was slipping or that the pulleys were dirty/coated. This did not make the chirp go away. A new belt was going in. Since there is no room to work he had to go in from the side after removing the right wheel and fender cover in order to have access to the pulley and belt. A new one was installed in 30 minutes. He also checked all the pulleys and found smooth spinning/operating and declared that all should be fine now. This was a $140 repair job but worth every penny if all will stay quiet. We are keeping our fingers crossed.BTW milage is 95K and I was told that serpentine belts on this model last from 80-100K. Also inquired what else will need to be replaced at 100K. Radiator hoses from Toyota for some reason last a long time but spark plugs are due next at 120K. Well how this all ended was actually a relief- we hope all will stay quiet. There you have it. Take care.
