PUMP
DESCRIPTION
Hydraulic pressure for the operation of the power
steering system is provided by a belt driven rotary
power steering pump. The power steering pump is a
constant flow rate and displacement vane type pump.
Vehicles equipped with the 2.7 liter engine use a
power steering pump that has an integral reservoir
for the power steering fluid (Fig. 1). Vehicles
equipped with the 3.5 liter engine use a power steer-
ing pump (Fig. 2) that has a remotely mounted res-
ervoir for the power steering fluid.
Both power steering pumps mount to the front of
the engine on the driver's side.
The service procedures for the power steering
pump are limited to the areas and components listed
below.
• Power steering fluid reservoirs, related compo-
nents and attaching hardware.
• Power steering pump pulley.
No repair procedures are to be done on the internal
components of the power steering pump. Repair of a
