Troubleshooting a Squealing Power Steering Pump Noise
Power steering pump noise it not only irritating, but it is also a sign that something could be wrong with the power steering system. There are some troubleshooting tips you can follow to help find out where the problem lies and how to solve it.
Tip 1 – Belts
If the belts are loose you will hear a squeal, especially when the engine is cold. Check all the belts on the vehicle, including the timing belt and fan belt. Tighten where appropriate and see if that makes a difference.
Tip 2 – Low Fluid
You may have a fluid leak. Check under the car and look for signs of leakage. As power steering fluid doesn’t get used by the system, the levels should not drop, so if there is no leak, just check the levels and top them up if needed.
Tip 3 – Air
You may have an air lock in the system. The best solution to combat this is to drain the system and free up any potential locks. Restock the fluid in the system.
Tip 4 – Worn Pump
The pump could actually have worn out. Maybe caused by age or simple wear and tear, so if this is the result in your findings, then replacing the pump is the only solution.
