In the current automotive market, hydraulic power steering systems (HPS) and electronic hydraulic power steering systems (EHPS) are still widely used, and both systems rely on power steering pumps.

As a luxury car, the replacement cost of the power steering pump of Buick LaCrosse is relatively high. The total cost is usually between $300 and $800.

A power steering pump is a device specifically used to provide hydraulic power to a vehicle's power steering system. Its main function is to convert the engine's mechanical energy into hydraulic energy, and through the flow and pressure of hydraulic oil, the auxiliary steering system reduces the force required by the driver to turn the steering wheel.

The power steering pump (Power Steering Pump) is one of the key components in the power steering system. Its main function is to generate hydraulic oil flow through mechanical force to provide power to the steering system.

Due to the different viscosities and compositions of the transmission fluid, it may not provide the ideal lubrication required by the power steering system. This will cause increased friction inside the pump and pipes, and long-term use may accelerate wear and shorten the life of the pump.
