What does the automobile rely on to function?
several systems to maintain function
Which of the following is the best way to diagnose a system failure in your car?
look for specific components in the system that are not working
What makes up a system?
A system is comprised of a few or many individual components that act together for a
greater purpose.
components
What does the coolant do?
The heat from the engine is transferred into the coolant.
Which of the following best describes what the thermostat does in the cooling
system?
The thermostat measures the temperature of the engine and, based on that
temperature, tells the water pump when to cycle coolant through the engine.
What is the main function of the radiator?
The main purpose for the radiator is to allow the heat from the antifreeze to be
transferred to the air that is being blown by the fan located directly beside it.
Where is the power generated that is transferred in the power train system?
The power for this system is generated in the engine of the system. The transmission is
connected directly to the engine.
What does the power train system do?
The power train system transfers the power that is generated in the engine through the
transmission, along the driveshaft, and then through the axles that connect to the drive
wheels.
Which one of the following components is a component of the power train
system?
transmission
radiator
brakes
steering wheel
transmission
What are the two inflation problems that cause premature wear on your tire, and
how can these problems be fixed?
Over-inflation, under-inflation. Both problems can be fixed by bringing the tire to its
appropriate pressure.
What causes the one-sided wear pattern?
The one-sided wear pattern occurs when the tires are out of alignment.
Why should you check your tire pressure regularly?
The fluctuation in the tire pressure is damaging to the tires and should be fixed as
quickly as possible.
, Which of the following can help even out the wear on all tires to increase their
life?
Rotate the tires every 6,000 miles.
When your wheels get out of alignment, what can be done to realign the tires?
A service technician will use specialized measuring tools and wrenches to reposition the
wheels.
How can you determine the appropriate pressure for your tires?
All tires have this information located on the outside wall of the tire. The manufacturer
places this information there.
Which two wear patterns can be fixed by adding or releasing air from the tire?
The only two patterns that can be fixed by adding or releasing air from the tire are
center wear and double-sided wear.
Why should the vehicle be in park or in gear during the process of changing the
tire?
When the vehicle is in park or in gear the wheels are held in position by gears and
cannot spin on their own.
How should the lug nuts be removed from the wheel?
in a star pattern
What is the purpose of a wheel chock?
to prevent the car from rolling
What are the four strokes of the engine called?
intake, compression, power, exhaust
During which stroke does the cylinder fill with flammable vapor?
intake stroke
Where in the engine does combustion occur?
cylinders
Besides lubricating the engine, what else does oil do?
Engine oil also cleans the engine, seals cylinders and valves, and helps keep the
engine cool.
What could happen to the metal parts of the engine if there were no oil?
If there is no oil in the engine there will be a lot of friction. Friction creates heat and the
metal parts of the engine can only support a certain amount of heat before they become
molten or grind themselves up.
What component of the lubrication system initiates the flow of oil through the
engine?
oil pump
Where can you find out which oil is recommended for your vehicle's engine?
The owner's manual contains all the information from the manufacturer including the
type of oil recommended for your vehicle.
What does viscosity mean?
The word viscosity refers to the physical property of the oil that allows it to resist flow
when pressure is applied. In simplest terms, it describes the thickness or thinness of the
oil.
What is the specific name for the additives in a type of oil called?
additive package
Why should you let the car run before you drain the oil?
