PUMP - SERVICE INFORMATION
DESCRIPTION
Hydraulic pressure for the power steering system is
provided by a belt driven power steering pump (4).
The pump shaft has a pressed-on drive pulley (5) that
is belt driven by the crankshaft pulley. The power
steering reservoir (1) is mounted to the pump body
(4), except if the vehicle has 5.7L or Diesel engines
then it has a remote reservoir mounted to the fan
shroud.
OPERATION
The power steering pump (4) is a constant flow rate
and displacement, vane-type pump. The pump internal
parts operate submerged in fluid. The flow control ori-
fice is part of the high pressure line fitting. The pres-
sure relief valve inside the flow control valve limits the
pump pressure. The reservoir is attached to the pump
body with three bolts (7), except if the vehicle is
equipped with a 5.7L or Diesel engine then it has a
remote reservoir mounted to the fan shroud. The
power steering pump is connected to the steering gear
by the pressure and return hoses.
NOTE: Power steering pumps have different pressure rates and are not interchangeable with other pumps.
