Question 13

16)The rubber material in timing belts can be either high-temperature ____________________ or highly saturated nitrile (HSN).

Question 14

12)All of the following statements are true EXCEPT:

A) when a belt is overtightened, parts can be overloaded.
B) a slipping belt can result in several problems, including severe engine damage.

15)Which of the following statements is LEAST-Likely true?

A) Power steering reservoirs are made of steel.
B) Do not pry on the power steering reservoir or any other delicate part.
C) Prying against unreinforced sheet metal will cause a dent, which can damage internal components of the pump.

Question 16

11)While having a discussion, Technician A says that a glazed belt must be replaced because it will not grip the pulley tightly. Technician B says that if tension on a glazed belt is adjusted at specification, there is no need to replace it. Who is correct?
