2015 FORD FLEX spark plug

•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 (U.S.) or Motorcraft
Premium Glass Cleaner (Canada).
•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.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.
Note:Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause damage
to the rear window defroster’s heated grid lines.
