CAADE - Certified Automotive Appraisal and Damage Estimator Vehicle Construction and Parts Questions and Answers

Question 1

An estimator is inspecting a bumper cover and cannot find an SAE identification code.
They perform an abrasion test on a hidden area of the part, and the material produces a powder rather than smearing.
Based on this test, what type of plastic is the bumper cover most likely made from, and what is the implication for its repair?

Accepted Answer

Thermoset; it can be repaired with a flexible two-part epoxy/adhesive.

Answer

Thermoplastic; it can be welded with a hot iron and plastic filler.

Answer

Polycarbonate; it requires replacement and cannot be repaired.

Answer

Fiber-Reinforced Plastic (FRP); it requires specialized fiberglass repair kits.

Question 2

A vehicle's radiator core support has been moderately damaged in a front-end collision. Which of the following best describes the primary functions of this component, beyond simply holding the radiator?

Accepted Answer

It aligns the front fenders and hood latch, and provides mounting points for headlights and the A/C condenser.

Answer

It acts as the primary crumple zone and houses the engine control unit (ECU).

Answer

It only serves to mount the radiator and cooling fans.

Answer

It is a non-structural cosmetic panel designed to direct airflow.

Question 3

Which of the following vehicle systems is considered an 'active' safety system, as opposed to a 'passive' one?

Accepted Answer

Automatic Emergency Braking (AEB)

Answer

Seatbelts

Answer

Airbags

Answer

Crumple Zones

Question 4

An estimator is assessing damage to a B-pillar and identifies it as being constructed from press-hardened steel (PHS), also known as Boron steel. According to most manufacturer repair guidelines, what is the generally accepted repair method for this component?

Accepted Answer

Repair is not recommended; the part must be replaced at factory seams.

Answer

Heat the area to 500°F and straighten using hydraulics.

Answer

Section the damaged area and weld in a replacement piece.

Answer

Use a stud welder and pull the damage out, then finish with body filler.

Question 5

In a unibody vehicle, the front frame rails are designed with specific indentations and shapes along their length. What is the primary purpose of these engineered features?

Accepted Answer

To control and absorb energy by collapsing in a predetermined manner during a collision.

Answer

To provide mounting points for suspension components.

Answer

To reduce the overall weight of the vehicle for fuel efficiency.

Answer

To allow for easier measurement during frame alignment checks.

Question 6

A technician is assessing a frame rail on a heavy-duty truck and notes it was manufactured using a hydroforming process. What is a key characteristic of a hydroformed rail that an estimator must consider when planning a repair?

Accepted Answer

They typically have variable thickness and complex, seamless shapes, often requiring specific sectioning procedures or full replacement.

Answer

They are always made of aluminum and require special welding techniques.

Answer

They are filled with a foam material that must be replaced after any repairs.

Answer

They can be heated and straightened without restriction due to their high flexibility.
