Two technicians are discussing cooling system hose
replacement. Tech A says to make sure that the hose clamps
get installed just inside the flared or barbed segment of the
fitting, not on top of it. Tech B says that it is good practice
to install new hose clamps at the same time as new hoses.
Who is correct?
a. Tech A
b. Tech B
c. Both A and B
d. Neither A nor B
