NHTSA recall 06V451000
Engine and engine cooling
Damon Challenger and 3 more
The defect
On certain motor homes built on workhorse chassis and equipped with gm 8.1L V8 engines, improper hardening during the heat treatment process can cause the fuel rail pulse damper retainer clip to fracture, resulting in inadequate retention of the damper. If the damper becomes loose, fuel could be pumped by the fuel pump into the under hood area.
The risk
In the presence of an ignition source, a fire could result.
The remedy
Chevrolet and workhorse are handling the owner notification and remedy for this campaign (please see 06v225 and 06v289). Dealers will replace the fuel rail pulse damper retainer clips on these engines free of charge. Owners may contact chevrolet at 1-800-630-2438, workhorse at 877-294-6773, or damon at 1-574-264-5517.
