  • Valeo premium alternators are 100% new products (not remanufactured)
  • 100% new components and core eliminates premature failure for increased durability over remanufactured units
  • All parts are application specific for an exact fit
  • Premium rare earth magnets increase the output of the alternator without increasing the size for better efficiency
  • All applications go under extreme condition testing up to 6 months to ensure reliability under the harshest conditions and electrical demands
  • High resistance to heat, vibration, and contaminating particles helps maintain maximum charge output.
The alternator on your Chevy Silverado keeps the engine running, keeps all the electronics powered, and ensures your battery is fully charged for the next trip. Magnets spinning inside of tightly coiled copper wire create an alternating electrical current that is converted to direct current to power the Silverado’s electrical systems. Failure of the alternator can be due to road debris or leaked engine fluids contaminating the magnets or coiled wire, diodes shorting out, or the internal regulator bushing wearing out. When this happens, the only solution is to replace the alternator. The Valeo 849158 alternator is a new 150amp direct replacement for the original equipment alternator part numbers 19244751 and 19244731 found in various Chevrolet, GM, and Cadillac trucks, vans, and SUVs from 2000 through 2010. Valeo is a top supplier of OEM alternators worldwide, having developed electrical systems for the automotive industry since 1923.
