Steering Vane Pump Functions, Failure Symptoms, and Replacement Cost

In this article, we are going to go over the basic functions of a steering vane pump, bad steering vane pump symptoms, and the average cost to replace a steering vane pump. So here we go:

Basic Functions of steering vane pump

All modern-day cars have power steering capabilities in them. In order for this ability to work, it needs a rotary vane pump to provide the steering with hydraulic power. The belt and pulley of the vehicle’s engine are what drives this pump to work properly. The vane pump is basically an oval chamber which has spinning retractable vanes inside of it. These spinning vanes turn low-pressure hydraulic fluid into high-pressure fluid. The pump regulates the flow of this fluid based on the speed that is demanded by the car’s engine. The faster the speed, the more fluid that is moved by the pump. However, there is a pressure-relief valve in the pump which ensures the pressure stays within a healthy range and doesn’t get too high.

Failure Steering Vane Pump Symptoms

If you have a failing steering vane pump, then there are a few symptoms you should watch out for. The first symptom is a whining noise that you hear each time you turn the wheel of your car. This is a clear indication that your power steering system is faulty. Usually, there is either a low level of power steering fluid in the system or your vane pump is leaking fluid. Another symptom of a faulty vane pump is when the steering wheel does not respond right away when you try to turn it. You may also hear a whining noise from this as well. Other symptoms you could experience are a stiff steering wheel when you turn the wheel and squealing noises when you first turn on the vehicle. As you drive, there may even be groaning noises made too. But no matter what noises there are, they will surely be noticeable and they’ll be a clear sign that you need to take your vehicle to the nearest auto body shop right away for repair.

The average Steering Vane Pump Replacement Cost

To get the best deal, you should choose a mechanic that has the lowest hourly rate. If you bring the vehicle to the auto body shop of a big time dealership, then they’ll likely charge you $99 per hour minimum. So, take that into consideration when you shop around for a mechanic.
