Product Details

Gates Micro-V belts are engineered for import and domestic cars and trucks that require a precise OE-style serpentine belt. The K050402 uses a K-section, standard automotive V-ribbed profile with five ribs, helping maintain proper belt tracking across accessory pulleys. Its EPDM construction and polyester cord reinforcement support consistent operation in the accessory drive system, while the OE-sized dimensions help ensure the correct fit for the listed applications. This part number is commonly searched for Chevrolet Malibu, Pontiac G6, and BMW X5 belt replacement needs.

This part cross-references Continental (e.g., 5K1023, 5PK1023) for the same application.

Common Problems This Belt Can Address

• Squealing or chirping from a worn serpentine belt
• Cracking, glazing, or rib wear on the existing belt
• Loss of proper drive to alternator and air conditioning accessories
• Belt stretch or poor tracking on the accessory drive system
• Replacement needs during routine maintenance on high-mileage vehicles

Installation Notes and Tips

Verify belt routing against the vehicle’s accessory drive diagram before installation. Confirm the belt length, rib count, and outside circumference match the original belt specification for your application. Inspect pulleys, tensioner condition, and accessory alignment before installing the new belt, since worn components can shorten belt life. Confirm fitment for 2007-2012 Chevrolet Malibu, 2006-2010 Pontiac G6, 2007-2010 Saturn Sky, 2006-2009 Pontiac Solstice, 2008-2009 Saturn Aura, 2005-2006 Chevrolet Malibu, 2005 Chevrolet Classic, 2004 Chevrolet Malibu, and 2002-2003 BMW X5 as listed.
