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
The windows and wiper blades should
be cleaned regularly. If the wipers do
not wipe properly, substances on the
vehicle
’s glass or the wiper blades
may cause squeaking or chatter noise
from the blades, and streaking and
smearing of the windshield.
To clean these items, follow these
tips:
• The windows may be cleaned with
a non-abrasive cleaner such as
Motorcraft® Ultra-Clear Spray
Glass Cleaner.
• The wiper blades can be cleaned
with isopropyl (rubbing) alcohol or
Motorcraft® Premium Windshield
Washer Concentrate in the U.S., or
Premium Quality Windshield
Washer Fluid in Canada. Be sure
to replace wiper blades when they
appear worn or do not function
properly.
• Do not use abrasives, as they may
cause scratches
• Do not use fuel, kerosene, or paint
thinner to clean any parts.
