Basic Car Safety Inspection
Introduction
A car operates using a variety of systems from the air conditioner to the power
steering and everything in between. Some systems require little maintenance so a
basic visual safety inspection is necessary. Other systems need a routine maintenance
schedule where a particular service or replacement is required. A car safety check
is included at all service intervals and is used to detect any malfunction do to
out side forces such as road debris and failed system components. In between service
intervals safety inspection are also necessary before a long journey to ensure safe
passage. Start with the vehicle in park on level ground, in cool condition with
the engine off. Next, release the hood latch and lift the hood, the hood will only
open slightly because all hoods have been designed with a secondary safety latch
that must be activated before the hood will open completely. Follow the checklist
below:
-
Checking
Fluid Levels - Check the engine oil level (engine off) the engine oil
level dip stick is usually indicated by a yellow handle. There are two level
indicator marks, upper level and lower level. The distance in between these
marks represent a quart, if the oil is in between the marks the level is ok.
If the oil level is below the lower level mark or not on the dip stick at all
engine oil must be added until between the inductor lines. Other Additional
fluid level inspections can include: transmission fluid, either standard or
automatic transmission fluid, power steering fluid, brake fluid, front and rear
differential fluids on some models. All fluids must be maintained to a proper
level, while some are easily checked others will require a lift. A standard
list of fluid level checks would be: engine oil, engine coolant, windshield
washer fluid, transmission fluid, brake system, power steering system (if equipped)
and differentials.
- Checking
Tire Wear Condition - Car tires are made out of flexible rubber which
is incorporated with wire and fabric. The tires of an automobile support the
braking, load, traction, and steering. Tires also absorb shock caused by bumps
in the road and help provide a smooth ride to the passengers. Tires need to
maintained at a prescribed air pressure and rotated at scheduled intervals.
Most vehicle tire pressure recommendations are located on a sticker in the driver's
door jam or on the side wall of the tire. While tire and car manufacturers recommend
a prescribed tire pressure, it has been shown that slightly more tire pressure
is optimal for achieving higher fuel economy by reducing rolling resistance.
Some hybrid cars are manufactured with tires that can hold up to 55 P.S.I. as
compared with the usual 32 P.S.I. For safety and better gas mileage always keep
your tires properly inflated. Tire rotation patterns are dependent on the vehicle
driving conditions and inflation. Most vehicle rotation pattern is straight
front wheels to rear wheels. Also check the air in your spare tire located in
the trunk, you never know when you will need it.
-
Checking Multi Rib Belt - A multi rib belt or drive belt is used to
supply power to the many accessories such as the alternator or water pump. These
belts are a normal service item and must be replace when signs of wear are present.
To inspect the multi rib belt release the hood latch and open the hood. The
belt is connected to the drive pulley of the engine to supply power. If the
belt fails it will almost always render your vehicle inoperable until the drive
belt is replaced. Typically most people are able to replace a serpentine belt
themselves with basic automotive repair knowledge. When replacing the belt draw
a diagram of the belt routing before you start to avoid confusion. If you have
removed the drive belt and need the belt routing you can look it up on a
belt routing
diagram.
- Checking
Engine Coolant Hoses - Engine coolant is used to transfer heat from
the engine to the radiator, if a
coolant leak
is present the engine will eventually overheat. Inspect the
engine coolant
level in the coolant reservoir tank, coolant level should be between the hot
and cold marks. Always check the coolant level when the engine is cold, preferably
over night. If the coolant level is not between the reservoir marks the cooling
system may have a leak.
-
Checking Safety Belt and
Air Bag
System - The safety systems in your car are designed to help prevent
injury in an event of a accident. There is no maintenance for these items just
visual and operational inspections. To check test the air bag safety system
start by sitting in the drivers seat with all doors closed. Turn the ignition
key to start the engine and allow to idle, the air bag warning light should
illuminate for about five seconds and then go out. If the air bag warring light
stays illuminated the system has shut down. (note: if an air bag warning light
is illuminated while driving the air bag safety system has been disabled and
will not activate in case of an accident.) Next, inspect all seat safety belts,
with the car engine off on level ground take each belt and pull it out completely.
Inspect the belt material for defects, tears or burn marks. Next check the retraction
action of the belt it should retract fully with no rough or weak spots. Replace
any seat belt that is damaged or shows signs of wear.
-
Checking Horn, Headlight and External Lighting Systems - The lights
in and around your vehicle are not only a convenience they are a safety precaution.
All lights on your vehicle should be working at all times, if fact it's against
the law for any exterior lights on your car not to be working. If it was designed
by the manufacturer to work on your vehicle it must work at all times. Make
it a regular check for your vehicle to assure the proper operation for your
lights.
-
Checking Wiper Blades - In foul weather is essential to have
new wiper blades to ensure proper windshield vision and control of the car.
Replacing car wiper blades is relatively simple, first move the wiper arm to
the upright position, next release the clip the attaches the wiper blade to
the wiper arm. check blades for cracking or tears in the wiper rubber. Then,
match up the new wiper blade to the old blade, next snap the new wiper blade
in place and lower the wiper arm, repeat this operation on the opposite side.

Travel Tips
Getting the Most from Your Gas?
It is no secret gas prices are up and putting a big pinch on our pocket books.
Car maintenance and driving habits significantly affect fuel economy. Here
are a few tips to help you get the most for your buck. First, check the air
pressure in your car's tires. Most vehicle tire pressure recommendations are
located on a sticker in the driver's door jam or on the side wall of the tire.
While tire and car manufacturers recommend a prescribed tire pressure, it has been
shown that slightly more tire pressure is optimal for achieving higher fuel economy
by reducing rolling resistance. Some hybrid cars are manufactured with tires
that can hold up to 55 P.S.I. as compared with the usual 32 P.S.I. For safety and
better gas mileage always keep your tires properly inflated. Next, analyze your
driving habits. Do you take off quickly from a stop? Try easing into the throttle
and allow the vehicle to accelerate slowly. Observe the traffic and signals
in front of you. If a stop is imminent release the gas peddle and allow the car
to coast the remainder of the distance before braking. Finally, proper maintenance
of your car's engine is essential for optimum performance. If your engine is misfiring
it will decease mileage. If engine oil and filter changes have been neglected it
will cause additional friction inside the engine and hinder performance and gas
mileage. Inspect your engine service records and perform a tune up or oil
change as recommended. Following these gas saving tips will increase your mileage
and save you money. To post your own gas saving tips please join our

Flat Tire on Freeway
A flat tire on the freeway or any other busy high can be very dangerous. There
are mainly two kinds of flat tires, either the tire is very low on air or the tire
is already flat and starting to fall apart. In the first condition (tire very low)
you have a chance to get off the freeway and into a safe place to change the tire
or wait for service. In the second case (flat and falling apart) is it best to not
worry about saving the tire, your main objective is to get to an freeway off-ramp
or other safe position to change the tire or wait for service. The car will have
more rolling resistance but will still move with a flat tire, proceed very slow
and use caution. When pulling off the the road to a safe place make sure your as
far off the road as possible. Most of the time when a tire is run very low on air
it will breakdown the inner layers and render the tire useless. If there is no close
off-ramp or safe place to stop get out of the car and walk to a more protected area.
Be conscientious about the tire worth or the tire and the safety of you and your
family. To many times people try to save a sixty five dollar tire and get hurt in
the process.
Car Storage Tips
If a car sits for a long period of time or in storage it
can have some of the same problems as a car that has been driven daily. If
a car is not prepared for storage properly it can create additional and unusual
problems. First of all the fuel system should be emptied to avoid fuel that can
gum up and clog the injectors or on older cars the carburetor. Next, disconnect
the battery and remove it. If the vehicle is in storage for any length of time
the battery wouldn’t be any good and you don't want excess battery acid leaking
out and onto the car’s chassis. When a stored car is put back into action
inspect the hoses and all other rubber components. Rubber components such as
hoses and intake boots are subject to natural discomposure. Always replace all
service filters such as air, oil and air cabin filters. Replace the engine oil
and coolant also.
Dim Instrument Cluster at Night
When driving at night where outside light is low it is
better to lower your instrument cluster lighting to avoid glare. Once the light
has been dimmed your eyes can better adjust to the darkness outside of the car
to increase visibility. Return dash lighting level back to normal when returning
to a more well lit area.
