Select one:
True
False
Which of the following statements regarding the “Pre-Emission Inspection Check” Of a diesel powered vehicle that is subject to Opacity (Smoke Meter) testing is not true?
The governor (if equipped), the exhaust system, and the emissions control devices must all be checked.
The exhaust system must be checked for any missing sections which would prevent collection of a valid exhaust sample.
Vehicles not meeting requirements cannot be inspected. This is not considered an inspection or rejection and no fee is to be charged.
The governor, if originally equipped, must be checked for presence, connection, and operation.
A vehicle has had several radiator
replacements, and each time there has been
pinhole leaks in the aluminum. Technician A
states that the engine coolant may need to be
exchanged more often. Technician B states
that the engine grounds should be inspected
closely since this could be the cause. Who is
correct?
Select one:
a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B
