Power Steering Pump: Description and Operation
DESCRIPTION
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 applications. The pumps are different depending on the engine option. The pump for the 2.4L
engine is made out of cast iron and steel. The pump used on the 3.3L/3.8L engine is made of aluminum.
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.
OPERATION
The power steering pump is a constant flow rate and displacement vane type pump. The power steering pump used on all applications is the
Vane-Submerged remote reservoir style power steering pump.
The remote reservoir type pump has the pump housing and internal components combined with the fluid housing. It has a remote reservoir for the
power steering fluid supply.
