Is the routine care you give your vehicle to avoid
more serious repairs
• Proper size of tire on your car.
• Never mix different types of tires.
Properly inflating the
tires ensures that they
will grip the road evenly
and wear at the same
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.
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
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.
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.
Fluids are the
lifeblood of your
If you have any reason to
suspect a problem with your
oil or if the oil gauge/indicator
light is activated, stop the
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
The oil level should be checked when
the engine is cool and not running.
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
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.
Make sure that there is enough
battery fluid for your battery.
Make sure that there is also
enough windshield washer
fluid in your car.
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.
Belts, Hoses, and Wires
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
Check all the hoses and the hose
connections for leaks.
Check all wires to make sure that they
are not loose, broken, or disconnected.
Also check for cracked insulation on the
If there is a problem with the wires,
they should be fixed or replaced.
The brakes are one
of the most
on your car!!
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.
You should let a mechanic know if:
You must depress the brake the
brake pedal very low to get it to

Your brakes grab, squeal or chatter.
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
Overheating can result from the
breakdown of you water pump or
thermostat. Suspicious knocking
noise, stop and turn off the engine.
Be alert to problems!

Experience considerable sway or bounce when
driving over a bump or turning corners.

Routine Maintenance Schedule
Check oil, windshield washer
fluid, radiator coolant.
Check the condition of the tires,
belts, hoses, automatic-
transmission fluid, brake fluid, and
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.
