Warranty
Federal Emission System Warranty
WARRANTY PERIOD
Navistar Inc. warrants your medium-heavy duty diesel engine
conforms with applicable emission regulations and is free from
defects in materials and workmanship which would cause such
engine to fail to conform with applicable emission regulations for
the following warranty period (whichever comes first):
•
5 years
•
100,000 miles (160,000 km)
•
Or if covered by any basic or extended warranty (if greater
than above)
Your medium-heavy duty diesel engine conforms to U.S.
Environmental Protection Agency regulations for emission
systems.
The engine model year, service class, and required emission
information is on the emission label attached on top of the valve
cover. This warranty is based on the engine model year, not the
model year of the vehicle. The warranty period begins on the
date the new vehicle is delivered to the first retail purchaser.
WARRANTY
REQUIRED MAINTENANCE
As the vehicle owner, you are responsible for all required
maintenance described in this manual. Navistar recommends
that you retain all maintenance receipts. Navistar will not deny
an emission warranty claim solely because you have no record
of maintenance. However, a claim may be denied if your failure
to perform proper maintenance resulted in the failure of a
warranted part and you cannot provide appropriate evidence
of maintenance. Take your vehicle to an authorized service
provider when a problem occurs.
WARRANTY REPAIRS AND SERVICE
All emission control system parts proven defective during normal
use will be repaired or replaced during the warranty period.
Warranty repairs and service will be done by an authorized
service provider with no charge for parts, labor, and diagnostics.
Warranty repairs should be completed in a reasonable time, not
to exceed 30 days. Navistar may deny warranty coverage if
your vehicle or a part has failed due to abuse, neglect, improper
maintenance, or unapproved modifications.
