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
Properly inflating the tires ensures that they
will grip the road evenly and wear at the same
rate.
Inflation
  • 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
Fluids are the lifeblood of your vehicle.
Fluid Levels
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
The brakes are one of the most important features
on your car!!
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
  • The quickest way to diagnose problems with your
    engine is from your exhaust.

Engine
  • 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
Be alert to problems!
  • 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.
