Estimating
What must be done with damaged fuel lines, exhaust/emission
systems? - ✔ ✔ Federal and state laws mandate they must be put
back in thier original condition and REPLACED, not repaired, since the
safety of the passengers are at risk.
Whats more hazardous, welding near a full tank of gas or an empty
one? - ✔ ✔ An empty tank is more hazardous. So never just
"empty" the gas tank, make sure you remove it if you're doing any
welding nearby.
What is a vapor canister? (fuel related) - ✔ ✔ It contains charcoal
granules that absorb fuel vapors and is often damaged during collisions.
Exhaust components consist of... - ✔ ✔ exhaust pipes, catalytic
converters, mufflers, resonators and tailpipes. (oxygen sensors are
apart of the engine management controls)
Most unitized body vehicles are equipped with what type of
suspensions and steering systems? - ✔ ✔ Strut-type suspensions
and rack and pinion steering systems. Although, multi-link front
suspensions are becoming increasingly common as vehicles assume the
lower hood profiles
Anytime there is structural damage to a unitized vehicle, or if a wheel
or tire is damaged or shows signs of impact, what should be included
on your estimate? - ✔ ✔ a 4 wheel alignment.
,What are the major steering and suspension angles you must be
familair with? - ✔ ✔ Toe, camber, caster and steering axis
inclination (SAI)
Whats the most common type of engine/transaxle design in front
wheel drive passenger cars? - ✔ ✔ "The Transversely Mounted
Engine/Transaxle" (transmission on the left or right of the engine and
no driveshaft)
A CV joint is also known as a... - ✔ ✔ Constant velocity Joint.
Bearing damage is often undetected until the vehicle is..... - ✔ ✔
operated on the road.
What is a Parallelogram type steering system? - ✔ ✔ The kind you
find on most old cars, with the big center link, tie rods, pitman arm and
adjustment sleeve (what we see on tractor trailers all the time)
What is rack and pinion steering? - ✔ ✔ What we see on most front
wheel drive cars, with tie rods, boots covering the rack housing and the
rack gear that moves the Pinion gear.
It is not unusual for a Hybrid vehicle to contain a charge of ______
volts. - ✔ ✔ 650 volts. Even a dead Hybrid battery can have a charge
of 300 volts, which can be lethal to humans. Always disable the service
link plug before working on a Hybrid, which is usually bright orange in
color
When is the removal of the Nickel Metal Hydride battery on a Hybrid
vehicle required? - ✔ ✔ 1: When welding within 12 inches of the
battery. 2: When access behind or under the battery is required.
(remember this when doing your estimate, as it takes a lot of time to
, remove these batteries). 3: When painting the car (this is because any
temperatures above 150 degrees F will cause damage.) Another option
is to let it air dry and not use the oven.
Technicians working on the vehicle electrical system should wear a
_____ _____ , to prevent any static charge. - ✔ ✔ static strap -
which is worn around the wrist and connected to a point on the
vehicles body.
What is the most common function of an electronic component? - ✔
✔ A Sensor, which sends data to the ECM.
Supplemental restraint systems (SRS) include: - ✔ ✔
driver/passenger airbags, side impact air bags and seat-belts.
Airbag system components include: - ✔ ✔ Airbag module, side
curtain module, clock spring, harness, cable, reel, control unit, labeling,
sensors and a harness to the sensors.
Seat-belts consist of: - ✔ ✔ Pre-Tensioners, reels and points of
attachment.
When servicing an airbag system, the components must be .... - ✔ ✔
Replaced, not repaired. Only some insurance companies will require
you to write for a salvage airbag and use should get a "hold harmless"
agreement if they require that.
TTY stands for... - ✔ ✔ Torque to Yield
Torque to Yield (TTY) bolts stretch when torque is applied and deform,
which makes them a .... - ✔ ✔ one time use bolt and must be
