Exam 12: Power Steering Pumps

All of these statements about a serpentine belt are true EXCEPT:

Where is the machined venturi located in the power steering pump?

What is the purpose of the vanes in the power steering pump rotor?

A loose power steering belt may cause belt squealing when cornering.

Excessive wear on the power steering pump mounting bolts may cause misalignment of the power steering belt.

What type of fluid do most car manufacturers recommend in power steering systems?

Explain the location and operation of a wear indicator on a multi-ribbed belt system.

Explain the type of vehicle that a hydro-boost power system is used on and the reasons for the use of this system.

When testing power steering pump pressure, the pressure gauge valve should be closed for no more than:

A press-on type power steering pump pulley may be installed by tapping on the pulley with a soft hammer.

Power steering pump pressure is highest when driving a vehicle straight ahead.

All of these statements about power steering pump design and operation are true EXCEPT:

A loose power steering belt may cause all of these problems EXCEPT:

Technician A says the same tool kit is used to remove and install a press-on-type power steering pump pulley. Technician B says power steering pump pulleys retained with a nut and lock washer have a woodruff key mounted in matching slots in the pulley and shaft. Who is correct?

When checking power steering belt tension by measuring the belt deflection, the maximum allowable belt deflection per foot of belt free span is:

What can cause excessive belt wear?

How is poor steering provided on hybrid electric vehicles when the engine is not running?

What happens to the pressure in the venturi as the fluid flow increases in the power steering pump?

A hydroboost power steering system:

Increased steering effort may be the result of air in the power steering system.
