Question

Quizplus · Accepted Answer

Technician B is correct. Late model cars use electric fans that sometimes continue to run after the engine is shut off to cool the engine down. Technician A is incorrect because temperature-controlled fan clutches use a bimetallic spring, not a spring that shrinks when heated and expands when cooled.
