Product Line Details

What It Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or visible wear on the existing serpentine belt
• Loss of belt grip affecting alternator or A/C operation
• Incorrect belt length after a previous replacement
• Accessory drive noise caused by belt deterioration

Installation Notes and Tips

Verify the belt routing and compare the existing belt length, rib count, and profile before installation. Confirm the application by vehicle year, make, model, and accessory drive position, since this part is listed for multiple configurations including alternator and air conditioning, air conditioning and alternator, fan and air conditioning, fan and power steering, power steering and water pump, and power steering. Inspect pulleys and tensioner components for wear before installing the new belt.
