Steering System - Electronic - Variable Power Assist: 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 steering pump (Fig 2) that has a remotely mounted reservoir 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 components 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 power steering fluid leak from any area of the power steering pump is not allowed.
