TSB Document:
Affected Component: ENGINE (PWS)
- Summary
- 17105 - Customer Satisfaction Program. Certain vehicles, equipped with a DuraMax Diesel Engine (L5P) and Dual Generators (KHB), may have been built with an accessory drive belt idler pulley intended for other applications. The pulley?s centerline and capacity differs from the design intent pulley. This difference in alignment and durability may cause the accessory drive belt at some point to come off the accessory drive system. Without an accessory drive belt, the vehicle will lose engine cooling, battery charging, power steering, power brakes, and air conditioning operation. All other systems will function normally. Delaers will replace the idler pulley the belt or both.
