Certain Mack and Navistar trucks equipped with certain Cummins Westport ISL G engines are being recalled for potential oil leaks that pose a fire risk, according to the National Highway Traffic Safety Administration.
Mack Trucks is recalling 2,571 2010-2016 model-year Granite (GU), LR, and TerraPro (LEU, MRU) trucks manufactured from Nov. 17, 2009, to Oct.17 of this year. They all have engines with a turbocharger oil supply line that might contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or air fuel control tube.
As a result, the turbocharger oil supply line might leak oil near the engine exhaust manifold. This increases the risk of a fire, NHTSA said.
In total, the recall affects over 3,000 vehicles equipped with engines potentially at risk.
Cummins will notify truck owners on behalf of Mack, and dealers will inspect for oil supply line interference or damage. If necessary, dealers will eliminate the interference and replace the oil supply line. There will be no charge for this service.
The recall is expected to begin Nov. 30. Truck owners can reach Cummins at (800) 343-7357 or Mack customer service at (800) 866-1177. Cummins’ number for this recall is SC0396.
