Product Details

Gates Premium OE Micro-V belts are engineered to match OE size, construction, and materials for factory-style accessory drive performance. This belt follows a K-section profile and is specified as an automotive V-ribbed belt, making it suitable for serpentine drive systems where accurate belt geometry matters.

This part cross-references Continental 5K1432 for the same application.

Common Problems This Belt Can Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of proper drive to the alternator or power steering system
• Air conditioning belt wear on factory-equipped Ford Thunderbird and Mercury Cougar applications
• Incorrect belt length or profile after a previous replacement

Installation Notes and Tips

Verify the belt routing, rib count, and measured length against the vehicle’s accessory drive layout before installation. For 2004-2005 Volkswagen Passat alternator and power steering applications, confirm the belt path matches the OE configuration. On 1980-1981 Ford Thunderbird and Mercury Cougar air conditioning applications, confirm the vehicle has the listed factory-installed equipment and the 57 1/8 in. belt outside circumference noted in the fitment data.

Inspect pulleys, tensioners, and idlers for wear before installing a new belt. A damaged pulley surface or weak tensioner can shorten belt life and affect drive performance.
