This lesson will focus upon
things the average person, with

Power Systems
Ignition/Electrical
System
Involved in the ignition process and
provides electrical power needed to
operate a vehicle.
Lubrication System
The use of oil, grease, and other
substances to reduce damage to
moving parts from heat caused by
friction.
Cooling Systems
Provides additional cooling and source
of heat for your vehicle’s interior in
cold weather.
Emission System
Takes the exhaust created by burning
fuel and forces it through the
exhaust system to outside of the
vehicle.

you should add air to your
tire as recommended.
Checking
Tire Pressure
• Some newer cars will
alert you when your
tire pressure is low
by displaying it on
the dash board.
• It is also a very
convenient way to
check your tire
pressure.
Tire Rotation
(usually about every 5000 miles)
• Tire rotation will allow
your tires to last much
longer.

• Remove the oil fill cap.
• Add the proper type
of oil according to
the owners manual
for your car.
(an oil funnel will keep
drips to a minimum)
When To Change Your Oil
About every 3,000 - 5,000 miles or 3 months
See owners manual for specifics
Checking
Brake Fluid

the brake fluid?
• If your brake
warning light is on
and your parking
brake is not set then
you may have a
problem with your
braking system
• If you notice a
squealing noise when
braking it could
mean your brake
pads are worn and
need replacing.

hot weather you should
turn on the heater and
fan on high; if the

should pull over and let
your car cool down.

Testing?
• Pull off the road so that

• Try to stop on a straight

are needed
to change
a tire?
Spare tire
Safety Note: A car can slip off of a jack, so
never put yourself in a position where the
car could fall on you.
1. Shift to Park
Set the parking brake
2. Block the wheel that is
diagonally opposite the flat
tire. Use a block of wood or a
large rock to firmly secure the
wheel.
3. Take out spare tire, jack, and lug
wrench. (they may be in the truck – consult
owner’s manual for exact location)
Position jack under the car
according to instructions.
4. Jack up the car high enough so the
flat tire still touches the ground.
5. Remove the wheel cover or
hubcap and loosen the lug nuts.
Some cars do not have
hubcaps...consult your owner’s
manual for proper instructions
in removing the tire
Sometimes the lug nuts are tight
and difficult to loosen…
If you can't loosen them, try
putting some of your weight on
the lug wrench to loosen them
6. Jack up the car until the flat tire
completely clears the ground.
Use the lug wrench to completely
remove the nuts and place
them in the wheel cover.
You will want the flat
tire about 6 inches off the
ground because the spare
tire is fully inflated and
will require more ground
clearance
7. Removing the wheel
– It’s easiest to grab the tire at
the 9 and 3 o’clock positions
- Pull the wheel straight
toward you, and off the car
• 8. Position the spare tire directly
in front of the wheel well
• Lift the spare tire and position it
on the threaded bolts
• Push the tire onto the car until it
cannot go any farther
• Replace the lug nuts on the bolts
and tighten them, but not too
tight...just enough to hold the tire
in place while you lower the car
• 10. Lower the car with the
jack until the car is again
resting on all four tires
• Alternately tighten the
lug nuts
• Lower the car with the jack
until the car is again
resting on all four tires
• Alternately tighten the
lug nuts
• Lower the car and put
on the wheel cover
