A) a pump that is driven by a belt from the crankshaft supplies hydraulic power to assist steering effort.
B) most power steering is hydraulic, with pressure supplied from the crankshaft by a belt-driven pump.
C) steering assist is needed most when the car is stopped or nearly stopped.
D) the power steering pump develops more unneeded flow at lower engine rpm and vehicle speeds.

Question

Quizplus · Accepted Answer

The power steering pump actually develops more flow at higher engine RPMs, which can lead to unneeded flow at higher speeds, not lower. The statement in D is incorrect because the pump's flow rate typically increases with engine speed, and most systems are designed to manage or bypass the excess flow at high speeds to prevent over-assistance.
