Have a strange belt noise issue.
Vehicle: 2008 Toyota Camry, 3.5L 2GR-FE V6
Mileage: 62,000
The vehicle has the original serpentine belt (no cracks, no dry-rotting, wear appears acceptable). Based on the VIN cut-off, the vehicle already has the updated pulleys and washers as outlined in TSIB#0385-08.
Issue: During cold start-up, there is noticeable belt-squeal when you place the car into “Reverse.” The noise does NOT occur at idle (in Park), nor does occur when the car is shifted into drive.
If you turn the A/C on while the car is in Reverse, the noise reduces or goes away completely. If the RPM is increased, the noise goes away.
You cannot duplicate the noise once the engine has been warmed up.
I am really puzzled on this one. The symptoms are not typical of a worn pulley, belt or tensioner. The only possibility left would be the alternator decoupler pulley.
What do you guys think?
