Dayco 5060665 serpentine belt for the 2000-2005 Toyota MR2 Spyder and other vehicles carries engine power to the belt-driven accessories. This Dayco drive belt is catalogued for the supercharger main drive.
Cracks across the ribs, frayed edges or a squeal at start-up can mean a belt is worn. Before you replace it, rule out a seized or misaligned pulley and a weak tensioner, since either one can wear out a fresh belt as fast as the old one.
The 2000-2005 Toyota MR2 Spyder, the 1997-2003 Buick Regal and the 1997-2003 Pontiac Grand Prix V6 3.8L are among the cars this belt fits, along with other vehicles. If your car is not named here, enter its year, make and model on the Buyer's Guide tab to see whether this belt is its match.
