2Preventive 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.
3Properly 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.
6Fluids 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.
8Transmission 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.
9Coolant
- 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.
10Other 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.
11Brake 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.
12Belts, 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.
13HOSES
- 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.
14The 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.
17Steering 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.
18Routine 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.
