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 Concentrates in the U.S., or
Motorcraft Premium Quality Windshield Washer Fluid in Canada.
Replace your wiper blades when they appear worn or do not function
properly.
•
Do not use abrasive materials, as they may cause scratches.
•
Do not use fuel, kerosene, or paint thinner to clean any parts.
