If you’re ever out driving in the cold and hear a loud groaning noise coming from your power steering pump, there’s a good chance it’s because of a cold site. This is when the power steering pump’s seals start to wear down, making weird noises as liquid and air flow inside the pump.
What is the Power Steering Pump Groaning Noise?
Power steering pumps make a groaning noise when cold, due to the reduced flow of fluid. The fluid is squeezed out of the pump by the engine as it starts and operates. This squeezing action makes the metal parts in the pump expand and contract, which creates the groaning noise.
Causes and Solutions to the Power Steering Pump Groaning Noise
If you are experiencing a power steering pump moaning noise when cold, there are several potential causes to consider. Some of the more common reasons for this type of noise include:
-A worn or defective pump seal
-A seized or frozen pump impeller
-Squeaky or collapsing suspension components
-Damaged or improperly installed steering gear
-Engineered fluid leaks
Conclusion
Your power steering pump may be groaning when you’re driving in cold weather, and there is a simple solution. Check to see if your power steering fluid level is low by adding a little more to the reservoir. If the problem persists after adding fluid, then your pump may need to be replaced.
