Dayco 17560 Accessory Drive Belt

Accessory Drive Belt for Classic Ford and Jeep Applications

The Dayco 17560 accessory drive belt is built for vehicles that rely on a single belt to drive critical front-end accessories. With a synthetic rubber compound, top-cog construction, and a 36-degree angle, it is suited for accessory drive systems that need consistent grip and stable operation across a wide temperature range.

Compatible With classic Ford F-100, F-150, F-250, F-350, E-Series vans, and select Jeep CJ and J10 applications, this belt is also used on certain Volvo 760 and 780 models. The Dayco 17560 is a direct replacement choice for air conditioning, idler, and fan drive applications where correct belt length and profile matter.

Detailed Description

Dayco 17560 is an accessory drive belt engineered for older belt-driven systems found in Ford trucks and vans, Jeep utility vehicles, and select Volvo passenger cars. Its top-cog construction improves flexibility for routing around accessory pulleys, while the synthetic rubber compound supports dependable performance in hot and cold conditions. This part cross-references Gates 9560 and Bando B3550 for the same application.

Use the Dayco 17560 when replacing a worn belt on vehicles such as the Ford F-150, Ford E-250 Econoline, or Jeep CJ7 with air conditioning and idler drive layouts. It also appears in fan and air conditioning applications on several classic Ford and Mercury models, making correct fitment verification important before installation.

What This Belt Helps Address

• Squealing or slipping accessory drive belts
• Cracking, glazing, or visible belt wear
• Loss of belt tension from age and heat exposure
• Accessory drive noise from a worn belt profile
• Poor belt tracking on pulleys with the wrong length or angle

Installation Notes and Tips

• Verify belt length, top width, and angle against the original belt before installation.
• Inspect pulleys, idlers, and tensioning components for wear or misalignment.
• Confirm the correct application for air conditioning, fan, or idler drive positions listed in the fitment data.
• Check belt routing carefully on Ford truck, van, and Jeep accessory drive systems.
• After installation, run the engine and recheck tracking and tension.

Quality Assurance

The Dayco 17560 is manufactured to SAE J636 and SAE J637 standards, supporting consistent dimensional and performance requirements for accessory drive service. Its construction and temperature range make it a practical replacement for classic Ford, Jeep, and Volvo belt-driven accessory systems.
