What This Belt Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of proper belt tension or tracking on the pulley system
• Reduced accessory drive performance on power steering or A/C/idler circuits
• Belt replacement needs on confirmed Subaru, Honda, Chrysler, Dodge, Nissan, and Saab applications

Installation Notes and Tips

Verify the belt routing and pulley alignment before installation, and compare the old belt’s length and rib count to the replacement. Confirm the vehicle’s accessory drive position and application notes, especially on the 2007 Subaru Forester with the manufacturer cutoff note and on vehicles listed for power steering or air conditioning and idler service. Inspect idler pulleys, tensioners, and accessory pulleys for wear before installing the new belt.

Quality Assurance

Dayco manufactures this belt to SAE J1459 and SAE J2432 standards, with EPDM and aramid reinforcement selected for accessory drive durability and temperature resistance. The 5040353 is specified for confirmed OE-style replacement applications across multiple makes and models.
