Detailed Description
Dayco 5040365 is a black serpentine belt designed for accessory drive systems that require a 4-rib K-section profile. Its EPDM rubber construction helps maintain belt integrity under heat and cold, while aramid reinforcement adds strength for demanding accessory loads. This makes it a practical replacement choice for vehicles using the same belt dimensions and rib count, including Ford Transit-150 and Ford Transit-250 models, as well as Ford Transit-350 and Ford Transit-350 HD applications with air conditioning service.
This part cross-references Gates K040365 and Continental-ContiTech PK040365 for the same application. It also aligns with fitments such as 2006-2009 Chevrolet Trailblazer, air conditioning and tensioner, and 2014-2019 INFINITI Q70, power steering, where the specified belt configuration matches.
What It Helps Fix
- Squealing or slipping accessory drive belt noise
- Cracking, glazing, or visible wear on the belt surface
- Loss of drive to air conditioning, power steering, alternator, or fan systems
- Incorrect belt length or rib profile during replacement service
- Reduced belt performance in hot or cold operating conditions
Installation Notes and Tips

This belt is listed across multiple positions, including air conditioning, power steering, fan and alternator, fan and power steering, and air conditioning and tensioner applications, so confirm the exact engine accessory layout for your vehicle. For fitment-based searches, this part is commonly selected for 2020-2026 Ford Transit-150 air conditioning service and 2014-2019 INFINITI Q70 power steering applications.
