Additives and Chemicals
This owner’s manual and the Ford Workshop Manual list the
recommended additives and chemicals for your vehicle. We do not
recommend using chemicals or additives not approved by us as part of
your vehicle’s normal maintenance. Please consult your warranty
information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids at the specified
intervals or in conjunction with a repair. Flushing is a viable way to
change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
monthly or at six month intervals.
Daily Owner Checks
EngineAir filter restriction gauge.
Engine oil level.
Engine coolant level.
Brake SystemAir brake reservoir automatic drain valve
operation.
Drain the air brake reservoir (manual valve).
TransmissionVisually check for fluid leakage.
Steering SystemPower steering fluid level.
System for evidence of fluid leaks.

Observation Maintenance Operation
Insufficient power shown in loaded
practice stop.Inspect the automatic slack
adjuster function.
Subpar vehicle handling qualities. Check the operation of the brakes,
clutch and steering.
1,2
Excessive noise from under the
cab or engine compartment.Inspect the vehicle for missing,
damaged or mislocated noise
shields.
Excessive engine noise. Check the engine performance and
the engine governor.
Engine overheats; excessive fan
noise; fan constantly runs at high
speed or wobbles due to worn
bearings.Inspect the fan, fan shroud and fan
clutch.
Excessive exhaust noise; smell of
exhaust fumes is experienced.Inspect the entire exhaust system
for holes, leaks, breakage,
looseness and corrosive damage.
Excessive engine compartment
noise.Inspect the engine air induction
system (including air ducts and air
filter) for loose, damaged or
missing components.
Poor steering; wandering;
excessive tire wear.Check front end alignment, inspect
the tires and tire pressure.
3
Vibration or abnormal tire wear
indicating imbalance.Balance the wheels and the tires.
Hard shifting or excessive
vibration.Check the transmission and engine
mountings.
2
High effort to shift; noisy
transmission.Check and adjust transmission
controls.2
Insufficient full-throttle power;
backfiring.Check fuel pump pressure.
Radiator cap does not hold
pressure.Clean the cap seal and cap surface
on the radiator.
Electrical power supply has
diminished.Check the battery terminals for
corrosion.
