PUMP
DESCRIPTION
DESCRIPTION - PUMP (2.4L/3.3L/3.8L
ENGINE)
Hydraulic pressure for the operation of the power
steering gear is provided by a belt driven power
steering pump. The power steering pump is mounted
on the back side of the engine on all engine applica-
tions. The pumps are different depending on the
engine option. The pump for the 2.4L engine is madeout of cast iron and steel (Fig. 1). The pump used on
the 3.3L/3.8L engine is made of aluminum (Fig. 2).
The pump for the 3.3L/3.8L engine does not have a
return fitting as the pump for the 2.4L engine does.
The power steering return hose on the 3.3L/3.8L
engine goes to the reservoir instead of the pump.DESCRIPTION - PUMP (2.5L DIESEL)
Hydraulic pressure for the operation of the power
steering gear is provided by a belt driven power
steering pump. The power steering pump is mounted
front lower right corner of the engine (Fig. 13).
The pump has a supply fitting for fluid coming
from the reservoir and a pressure port for exiting
fluid that is headed for the steering gear.
