Ford will reimburse you for the cost of these warranty repairs including
diagnosis, if you take the part(s) that are replaced and the repair
receipt(s) to a Ford Motor Company dealer. The reimbursement shall not
exceed Ford's suggested retail price for the warranted parts that are
replaced and labor charges based on Ford's recommended time
allowance for the warranty repair and the geographically appropriate
hourly rate.
WHAT REPLACEMENT PARTS SHOULD I USE?
Ford Motor Company recommends that you use genuine Ford
replacement parts. However, when you are having non-warranty work
done on your vehicle, you may choose to use non-Ford parts.
If you decide to use non-Ford parts, be sure they are equivalent to Ford
parts in performance, quality, and durability. If you use replacement
parts that are not equivalent to Ford parts, your vehicle's emissions
control systems may not work as effectively, and you may jeopardize
your emissions warranty coverage.
For vehicles within the warranty period, Ford will repair at no cost to
the owner, under the Federal Emissions Warranty, covered emission
failures caused by properly installed Ford parts or non-Ford parts that
have been "certified" by the U.S. Environmental Protection Agency
(EPA). Ford is not responsible for the cost of repairing any emission
failures caused by non-Ford parts that have not been "certified" by the
EPA.
The maintenance, replacement, or repair of emissions control
devices or systems can be performed by any automotive repair
establishment or individual using Ford replacement parts or EPA
certified parts without voiding your federal warranty coverage
for future repairs during the warranty period.
