TORQUE SPECIFICATIONS
The power steering system consists of
- power steering pump
- fluid reservoir
- rack-and-pinion steering gear
- fluid cooler
- power steering pressure and return lines/hoses
- inner tie-rod
The power steering system uses a vane-type pump to pump the fluid from the reservoir to the rack-and-pinion steering gear. The power steering pump is mounted to the engine and is driven by the accessory belt from the engine crankshaft. Power steering fluid is pulled into one side of the pump from the reservoir by vacuum. The power steering fluid is then trapped and squeezed into a smaller area inside the pump. This action pressurizes the fluid as it flows to the rest of the system. A pressure relief/flow valve is built into the pump to control the maximum pressure. The relief pressure is between 9,200-10,205 kPa (1,334-1,480 psi). This action prevents damage to the system during different engine speeds. The power steering fluid, while under pressure, flows through the high pressure power steering line to the rack-and-pinion steering gear.
