A-Premium Serpentine Belt 5-Rib 55.13 in — EPDM, OE K Cross-Section for Chevrolet Cruze & Saturn 4-Cyl

The A-Premium 5-rib serpentine belt (55.13 in effective length) is a direct-fit, EPDM replacement designed to restore drive accessory function on compatible Chevrolet and Saturn 4‑cylinder engines.

This heavy-duty serpentine belt from A-Premium is engineered to replace worn factory belts on specific Chevrolet Cruze and Saturn models. Built with EPDM rubber and polyester cord, it matches OE cross-section K sizing and runs quieter with improved resistance to heat, oils and environmental contaminants. The belt ships with a one-year unlimited-mileage guarantee and is intended for gasoline engines only; confirm compatibility with your vehicle year and engine variant before purchase.

Will this belt fit my Chevrolet Cruze or Saturn vehicle?

Compatibility is limited to the listed vehicle and engine combinations; this belt fits several Cruze and Saturn 4-cylinder applications. Verify your model year, engine displacement and accessories (power steering, air conditioning) against the fitment notes before ordering.

• Chevrolet Cruze 2012–2015 L4 1.4L and Cruze Limited 2016 L4 1.4L (Gasoline)
• Saturn SL/SL1 1992–2001 L4 1.9L — manual steering, no A/C
• Saturn SC1/SW1 1993–1999 L4 1.9L — without A/C or power steering
• Cross-reference numbers: K050551, 5PK1398 and OEM equivalents included

How does this belt improve reliability compared with older belts?

A-Premium’s belt uses EPDM compound and a polyester cord to resist cracking, oil degradation and environmental wear that commonly shorten belt life. The design delivers stable tension and reduced vibration, which helps preserve accessory bearings and pulleys.

• EPDM construction for long-term resistance to heat and chemicals
• Polyester cord for consistent tensile strength and stretch control
• Precision K cross-section for correct tensioner alignment and quieter operation
• Manufacturing tolerances matched to OE dimensions to lower failure risk

What should I check before installing the A-Premium serpentine belt?

Inspect pulleys, the tensioner and idler bearings before fitting a new belt; a worn tensioner or misaligned pulley will shorten belt life even if the belt itself is new. Clean pulley grooves and verify pulleys rotate smoothly to ensure correct seating and tension.

• Check tensioner spring tension and pivot smoothness
• Examine idler and accessory pulleys for lateral play or roughness
• Clean grooves of debris and oil to prevent slippage
• Confirm the belt routing and proper tension after installation

What are the key specifications and warranty details I need to know?

The belt measures 55.13 inches effective length with an outside circumference near 55.694 inches and a 5-rib K-profile top width of roughly 0.667 inches. A-Premium backs this part with a one-year unlimited-mileage guarantee for added buyer confidence.

Who is this for: The A-Premium 5-rib 55.13 in serpentine belt is intended for DIY mechanics and professional technicians replacing a worn or damaged belt on compatible Chevrolet Cruze or Saturn 4-cylinder models.
