2. Preventive Maintenance
Is the routine care you give your vehicle to avoid
more serious repairs
Tire Maintenance
• Proper size of tire on your car.
• Never mix different types of
tires.

3. Inflation Properly inflating the
tires ensures that
they will grip the road
evenly and wear at
the same rate.
 Under inflated = grip the road only at the
outside edges, which cause the tires to squeal,
makes steering more difficult, leads to heat
buildup, decreases fuel economy, and wears
the tires out faster.
 Over inflating = allows only the center of the
tires to grip the road, which leads to a harder
ride, a reduction in the depth of the tires’ print,
and faster wear.

4.  Check tire pressure at least once a month
or when you stop to get gas.
 Make sure that you do so only when the
tires are cold. Because the heat from friction
with the road causes air in the tires to
expand.
 When you check your regular tires,
remember also to check the spare.
 It is illegal, as well as dangerous, to drive
on tires that are badly worn.

5.  Most tires have tread-wear indicators that
tell you when they should be replaced.
 If your tires do not have tread-wear
indicators, you should replace the when the
tread wears down to no less than 1/8 inch.
 Look for bulges and embedded nails,
glass, or metal.
 For equal wear, tires should be rotated on
a regular basis, which means switching
them from front to rear.

6. Fluid Levels Fluids are
the
lifeblood of
your
vehicle.
Oil
If you have any reason to suspect
a problem with your oil or if the oil
gauge/indicator light is activated,
stop the vehicle immediately!

7.  If you keep driving, you may do
irreparably damage your vehicles engine.
 Running an engine without oil is a sure
death sentence for the engine.
 Check the oil level at least once a
month, more frequently on older cars.
 Change the oil at least every 2 to 3,000
miles.
 The oil level should be checked when
the engine is cool and not running.

8. Transmission Fluid
 The color of the fluid should be a
bright, cherry red.
 Have a mechanic examine the
transmission if the color is dark and
has a burnt smell.
 Transmission fluid should be changed
every 25,000 to 35,000 miles
depending on the type of vehicle.

9. Coolant
 Check the level of the coolant in the
radiator overflow tank.
 The engine could become
overheated and damaged if the level of
coolant is insufficient.
 The engine should be running while
the coolant is being added.

10. Other Fluids
 Make sure that there is enough
battery fluid for your battery.
Make sure that there is also
enough windshield washer
fluid in your car.

11. Brake Fluid
 Have the fluid level in the dual master
cylinder checked every time you have
the oil changed and replace it at least
once a year.
 Brake fluid attracts water from
condensation and humidity in the air,
causing corrosion in the master and
wheel cylinders and shortening their
lives.

12. Belts, Hoses, and Wires
BELTS
 Belts should feel tight when you push
down on them. The belt should be
tightened if you can push it down more
than ½ an inch.
 A loose belt can cause electrical system
problems, inefficient cooling, and
problems with power steering and air
conditioning.

13. HOSES
 Check all the hoses and the hose
connections for leaks.
WIRES
 Check all wires to make sure that they
are not loose, broken, or disconnected.
Also check for cracked insulation on the
wires.
 If there is a problem with the wires,
they should be fixed or replaced.

14. Brake Pads
Test the brakes by stepping on the
brake pedal. You should feel firm
resistance and you should come to
a smooth, direct stop. The pedal
should be well above the floor.

15. You should let a mechanic know if:
 You must depress the brake the brake
pedal very low to get it to work.
 The vehicle pulls to one side when you
brake.
 One tire locks when braking.
 You detect a “spongy” feeling in the
brake pedal.
 Your brakes grab, squeal or chatter.

16. Engine  The quickest way to
diagnose problems with
your engine is from your
exhaust.
 Exhaust changes to a blue or smoky white
color = engine damage.
 Notice a foul, sulfuric odor like rotten eggs,
= a damaged catalytic converter.
 Overheating can result from the breakdown
of you water pump or thermostat. Suspicious
knocking noise, stop and turn off the engine.

17. Steering and
Suspension
 Vibration of the steering wheel.
 Excessive “play” in the wheel.
 Difficulty in steering even though tires are
properly inflated.
 Feel a wobbling.
 Vehicles pulls to one side under normal
conditions.
 Experience considerable sway or bounce when
driving over a bump or turning corners.
 Detect rattling, could be faulty shocks.

18. Routine Maintenance Schedule
 Every week;
 Check oil, windshield washer fluid,
radiator coolant.
 Every month;
 Check the condition of the tires, belts,
hoses, automatic-transmission fluid,
brake fluid, and power-steering fluid.

19.  Once a year;
 Check the air conditioner refrigerant
and shock absorbers.
 Replace the air filter and windshield
wiper blades.
 Flush out the radiator and refill it
with coolant.
 Hose down the undercarriage to
remove dirt and salt after a cold
driving season.
Check the headlight alignment.
