IMPORTANT: SAFETY
SAFETY ? RECALL FOR REPLACING THE FUEL PUMP
MODELS INVOLVED - C7 and C9 School Bus Engines
Dear Caterpillar Product Owner:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. This notice is also in accordance with the requirements of the Canadian Motor Vehicle Safety Act. Caterpillar has decided that a defect which relates to motor vehicle safety exists in school buses equipped with certain Caterpillar C7 & C9 engines.
A fuel pump failure will dilute the engine oil with fuel and may cause the turbocharger to fail and cause loss of throttle control and excessive smoke, both of which may result in a situation where a vehicle crash could occur. A new fuel pump will be installed on the engine. You will not be charged for the service performed.
If you would like to identify the Vehicle Identification Number (VIN) that matches the referenced engine serial number(s) please contact Caterpillar at this toll free number (800) 447-4986.
