Some 2001-04 GS and LS 430s, as well as 2002-04 SC 430 models, may give off an irritating squealing or chirping sound when the engine is first started. Lexus has traced the problem to drive belt slippage at one or more of the pulleys, idlers or tensioner. Installing an updated drive belt with a new rubber compond and improved rib design should help quell the racket immediately. Order Part number 90916-02586 for the GS and LS 430 models 90916-02584 for the SC. Any Vin after JTHBN3#F#40152349 fot the LS will have the new belt.
