ContiTech Accessory Drive Belt

ContiTech Accessory Drive Belts: OEM Expertise in Every Rib

When it comes to keeping your engine's accessories spinning — the alternator, power steering pump, air conditioning compressor, and water pump — few names carry the weight of ContiTech. As the engineered rubber products division of Continental AG, ContiTech brings more than 150 years of materials science to the accessory drive belt category, and its products reflect that depth of knowledge at every turn.

What sets ContiTech apart from generic aftermarket alternatives is a simple but powerful fact: these are the belts already on the cars. ContiTech is a leading OE supplier of drive belts to automakers worldwide, meaning the accessory drive belts you find here are engineered to the same specifications as the ones that came off the assembly line. That translates directly to precise fit, form, and function — no guesswork, no compromise.

Product Lines & Technology

ContiTech's accessory drive belt lineup spans several purpose-built product families designed to match specific engine architectures:

• Conti-V Multirib™ Serpentine Belts — The flagship multi-ribbed belt for modern accessory drives. ContiTech's advanced EPDM rubber compounds virtually eliminate the chirps, squeaks, and squeals associated with pulley misalignment, while a specially treated polyester tension member reduces elongation and remains highly compatible with the automatic tensioners used in today's belt drive systems.
• OE Technology Series Multi V-Belts — Built to mirror the exact OE belts installed on vehicles at the factory. These belts are precision-engineered for applications where reliability is non-negotiable.
• Stretch Belts — Designed specifically for accessory drives that lack a mechanical tensioner or an adjustment slot. ContiTech's Stretch Belt uses a polyamide tensile cord that stretches during installation, then recovers to maintain proper tension throughout its service life — all without the need for additional tensioning hardware.
• Dual-Sided Multi V-Belts — Featuring ribs on both sides, this design accommodates smaller-diameter pulleys, backside drive pulleys, and automatic tensioners. Advanced compounds keep the belt flexible and running cooler for greater wear resistance in demanding under-hood environments.
• V-Belts — For older or specialized engine layouts, ContiTech's V-belts deliver higher heat and abrasion resistance. A polyester tensile member improves dimensional stability, controlling elongation and limiting belt slip.

Materials & Quality Standards

ContiTech builds its accessory drive belts using progressive materials including fiberglass, polyester reinforcing fibers, HSN, and EPDM compounds — each chosen to maximize durability and performance in the harsh under-hood environment. Service life on ContiTech serpentine belts can reach up to 150,000 miles, making them one of the longer-lasting options in the aftermarket. As an ISO/TS 16949-certified manufacturer, ContiTech holds every belt to rigorous OEM standards before it ever leaves the production line.

Whether you drive a European import or a domestic vehicle, ContiTech's broad coverage spans all major makes and models. If you're replacing a worn serpentine belt, browse the full accessory drive belt selection or explore everything ContiTech has to offer across its complete product range.
