FORD 2002 Explorer v.3 - Manual (Page 299)

Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
Repairing paint chips
Minor scratches or paint damage from road debris may be repaired with
the Ultra Touch Prep and Finishing Kit (F7AZ-19K507–BA), Lacquer
Touch-up Paint (ALBZ-19500–XXXXA), or Exterior Acrylic Spray
Lacquer (ALAZ-19500–XXXXA) from the Ford Car Care Chemicals line.
Please note that the part numbers (shown as XXXX above) will vary with
your vehicle’s specific coloring. Observe the application instructions on
the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
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 with cold water to avoid cracking the engine block or
other engine components.
• Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
