ContiTech K49314A Accessory Drive Belt Kit with Tensioner and Idler Pulleys

The ContiTech K49314A Accessory Drive Belt Kit provides a complete serpentine belt system replacement solution in one convenient package. This OE-quality kit includes a 6-groove serpentine belt measuring 99 inches in length and 0.83 inches in width, along with an automatic belt tensioner and idler pulleys to ensure proper belt tension, guidance, and power transmission.

Kit Includes:

• 6-groove serpentine belt (99 inches long, 0.83 inches wide)
• Automatic belt tensioner
• Grooved surface steel idler pulley (3.54" diameter, 0.670" bore, 1.22" wide)
• Smooth surface steel idler pulley (3.54" diameter, 0.670" bore, 1.19" wide)

Key Features:

• OE-quality construction with polychloroprene rubber cover and body
• Polyester fiber tensile members for superior durability and strength
• Oil-resistant and temperature-stable from -22°F to 176°F (-30°C to 80°C)
• Service life intervals up to 150,000 miles
• Designed to prevent uneven wear, belt slippage, and loss of tension

ContiTech engineers recommend replacing all serpentine belt drive components simultaneously rather than individual parts. This complete system approach prevents premature belt wear, maintains proper tension, and reduces the risk of complete system failure that could lead to costly repairs. The belt's advanced ribbed design handles higher engine speeds, provides cooler running temperatures, and reduces operational noise.
