WASHINGTON, D.C. --- Caterpillar Inc. is recalling 1,512 C15 6-cylinder, 15L turbocharged, air-to-air after cooled diesel engines of 472 to 585 horsepower, the National Highway Traffic Safety Administration reported.  

The after-treatment regeneration device (ARD) may develop a hole, and heat and flame may escape during a regeneration of the diesel particular filter. This condition could result in a fire, NHTSA said on its website.

Each vehicle manufacturer will file a defect report and remedy plan for their vehicles that included these engines as original equipment. Vehicles will be repaired by Caterpillar at no cost to the owner.

Owners can contact either their vehicle manufacturer or Caterpillar at (800) 447-4986.
