California Proposition 65 Warning: Diesel engine exhaust, some
of its constituents, and certain vehicle components contain or
may emit chemicals known to the State of California to cause cancer or
birth defects or other reproductive harm.
Your new Diesel engine will feel, drive and function somewhat differently
than a gasoline engine. Therefore it is very important that you read and
thoroughly familiarize yourself and others operating the vehicle with this
guide.
This guide will acquaint you with the Power Stroke (7.3L DIT) Diesel
engine. It provides recommendations on engine care and operating
procedures. For complete vehicle information, also refer to the Owner
Guide included with the vehicle. It also describes equipment and gives
specifications for equipment that was in effect when this guide was
approved for printing, and should be considered a permanent part of the
vehicle.
Some aftermarket products may cause severe engine and/or
transmission damage. There are various manufacturers offering
devices to increase turbocharger boost, exhaust brakes to
increase stopping/hauling capacity or other such devices to
increase the power/torque of the 7.3L engine. Many owners’ past
experience with these products has been very poor. Severe
powertrain damage may result from the use of these aftermarket
products which will not be covered by the Ford warranty.
Ford may discontinue models or change specifications without any notice
and without incurring obligations.

with theFord Ambulance Preparation Package.In addition, Ford
urges ambulance manufacturers to follow the recommendation of the
