CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
•
Do not spray a hot engine with cold water
to avoid cracking the engine block or
other engine components.
•
Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine Shampoo.
•
Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
•
Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or the
area in and around these locations.
•
Cover the battery, power distribution box,
and air filter assembly to prevent water
damage when cleaning the engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
•
Clean the windshield with a non-abrasive
glass cleaner. When cleaning the interior
of the windshield, avoid getting any glass
cleaner on the instrument panel or door
panels. Wipe any glass cleaner off these
surfaces immediately.
•
For windshields contaminated with tree
sap, chemicals, wax or bugs, clean the
entire windshield using steel wool (no
greater than 0000 grade) in a circular
motion and rinse with water.
•
Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals from
the inside of the heated rear window. The
vehicle warranty does not cover damage
caused to the heated rear window grid lines.
