engine MAZDA MODEL B2300 TRUCK 2008 (in English) Repair Manual

•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
• Always read the instructions before using the products.
ALUMINUM WHEELS AND COVERS
Aluminum wheel rims or covers are coated with a clearcoat paint finish.
In order to maintain their shine:
• Clean with cool or lukewarm water and a neutral pH shampoo.
• Never apply any cleaning chemical to hot or warm wheel rims or
covers.
• Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
• Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
• To remove tar and grease, use Extra Strength Tar and Road Oil
Remover (0000–77–410E-01), available from your authorized Mazda
dealer.
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.
• Never spray the engine or other engine components with water. Water
will damage the engine or other engine components.
• Spray Engine Shampoo and Degreaser (0000–77–410E-09), available at
your authorized Mazda dealer, on all parts that require cleaning and
pressure rinse clean.
• Cover the highlighted areas to prevent water damage when cleaning
the engine.

• Never wash or rinse the engine while it is running; water in the

PLASTIC (NON-PAINTED) EXTERIOR PARTS
Use only approved products to clean plastic parts. These products are
available from your dealer.
• For routine cleaning, use cool or lukewarm water with a neutral pH
shampoo.
• If tar or grease spots are present, use Extra Strength Tar and Road Oil
Remover (0000–77–410E-01), available at your authorized Mazda
dealer.
WINDOWS AND WIPER BLADES
The windshield, rear and side windows and the wiper blades should be
cleaned regularly. If the wipers do not wipe properly, substances on the
vehicle’s glass or the wiper blades may be the cause. These may include
hot wax treatments used by commercial car washes, water repellant
coatings, tree sap, or other organic contamination; these contaminants
may cause squeaking or chatter noise from the blades, and streaking and
smearing of the windshield. To clean these items, follow these tips:
• The windshield, rear windows and side windows may be cleaned with
a non-abrasive cleaner such as Ultra-Clear Spray Glass Cleaner
(0000–77–400E-01 and 0000–77–400E-02), available from your
authorized Mazda dealer.
• The wiper blades can be cleaned with isopropyl (rubbing) alcohol or a
windshield washer concentrate. This washer fluid concentrate contains

SCHEDULE 2 — SPECIAL OPERATING CONDITIONS
If your driving habitsFREQUENTLYinclude one or more of the
following conditions:
• Short trips of less than 10 miles (16 km) when outside temperatures
remain below freezing.
• Towing a trailer, or carrying maximum loads.
• Operating in severe dust conditions.
• Operating during hot weatherin stop-and-go “rush hour” traffic.
• Extensive idling, such as police, taxi or door-to-door delivery service.
• High speed operation with a fully loaded vehicle (max. GVW).
• Off-road operation
Change ENGINE OIL AND OIL FILTER every 3 months or 3,000 miles
(4,800 km) whichever occurs first.
NOTE: Idling the engine for extended periods will accumulate more
hours of use on your vehicle than is actually indicated by the mileage
odometer. Consequently, the odometer reading can be often misleading
when determining the right time to change your engine oil and filter. If
you are using your vehicle in a manner which allows it to remain
stationary while the engine is running for long periods (door-to-door
delivery, taxi, police, power/utility company trucks, or similar duty), then
Mazda recommends you increase the frequency of oil and filter changes
to an interval equivalent to 200 ENGINE HOURS or use. Since most
vehicles are not equipped with hour-meters, it may be necessary for you
to approximate your idle time and plan oil/filter changes accordingly.
