Dayco 5040490DR Serpentine Belt - 6-Rib 49.0" EPDM Drive Belt

The Dayco 5040490DR is a heavy-duty serpentine belt engineered to deliver reliable power transmission across multiple engine accessories. Designed to OEM specifications, this multi-ribbed drive belt transfers power from the crankshaft to components such as the alternator, power steering pump, air conditioning compressor, and water pump.

Key Features:

• EPDM Construction: Made from Ethylene Propylene Diene Monomer (EPDM) rubber for superior heat, ozone, and wear resistance compared to older neoprene belts
• 6-Rib (6PK) Profile: Provides smooth, efficient power transfer with reduced vibration and noise
• 49.0" Effective Length: Part number encodes key dimensions — "490" denotes the 49.0-inch belt length
• OEM-Quality Fit: Engineered to meet or exceed original equipment specifications for direct, no-modification installation
• Crack & Wear Indicators: Dayco's DR (Drive) series belts feature built-in wear indicators to help identify when replacement is needed
• High-Temperature Resistance: Formulated to withstand the extreme underhood temperatures common in modern engine bays
• Reduced Stretch: High-tensile cord construction minimizes belt elongation over time, maintaining proper tension throughout service life

The Dayco 5040490DR is a direct-fit replacement serpentine belt suitable for a wide range of passenger cars and light trucks. As one of the most trusted names in belt and hose technology, Dayco products meet rigorous quality standards for durability and performance.
