Detailed Description

Dayco 15330 is an accessory drive belt for vehicles that use a narrow, cogged belt in the belt drive system. Its synthetic rubber compound and top-cog construction support reliable belt tracking in applications such as power steering, alternator, water pump, air conditioning, and fan drive routing, depending on the vehicle and accessory layout. This part number is used across many older import and domestic platforms, including BMW 325i, Suzuki Samurai, and Chevrolet Sprint applications listed in the fitment data.

This belt cross-references Gates 7330 for the same application. If you are replacing a worn belt on a vehicle that calls for Dayco 15330, match the routing, accessory position, and measured belt length before installation.

What It Helps Address

• Squealing or slipping accessory drive belts
• Cracking, glazing, or visible belt wear
• Loss of alternator, power steering, or water pump drive performance
• Poor belt tracking on cogged accessory drive systems
• Incorrect belt length after a previous replacement

Installation Notes and Tips

• Verify the vehicle’s accessory position before ordering; fitment varies by fan and alternator, power steering, air conditioning, and air pump routing.
• Confirm belt length against the existing belt or service information, especially on older Chevrolet, Ford, BMW, Saab, and Suzuki applications.
• Inspect pulleys, tensioners, and accessory alignment before installing the new belt.
• Check for air conditioning, idler, or engine-option notes in the fitment listing to ensure the correct application.

The 15330 part number is used in OE and aftermarket cross-reference listings for multiple vehicle platforms, including BMW 325i, Suzuki Samurai, and Chevrolet Sprint applications.
