What to do if power steering whines when cold?
Gently lubricate the new O-ring with clean power steering fluid, and carefully install in the fitting. Insert the fitting into the pump, and tighten with the wrench. Start the engine and top off the power-steering pump with clean fluid. Bleed the system to remove any trapped air. hand on steering whell image by Andrzej Borowicz from Fotolia.com
What to do if your power steering pump is making noise?
If your power steering pump is making noise and you can’t get a new one, the best thing to do will be to keep it full of fluid to make sure no further damage occurs. Sometimes power steering pumps can get noise and last for a long time continuing to make that noise.
Why does my steering whine when I change the fluid?
If you’ve kept up with regular maintenance on your car including changing your power steering fluid as recommended, then the whine is most likely due to air bubbles in your system. Air can get in your power steering system from a few different sources. First, you could have air bubbles in your power steering fluid due to a loose low pressure hose.
How does a power steering pump work on a car?
Your power steering pump is required to take the rotary motion of your engine’s crankshaft and convert it into high pressure fluid that can be used to assist you in turning the heavy wheels of your car. Your power steering pump does this by attaching a belt and pulley to a rotary vane pump.

Why do I hear a whine from my power steering pump?
Inside the pump housing is a rotor with vanes or blades attached to it. When spinning, these vanes throw the power steering fluid into the outlet hose on the pump creating the high pressure needed for the system. It is the special design of the vane and rotor that creates the unique whine you hear when your power steering isn’t operating correctly.

Why does my power steering make a whining noise?
Check the level of your power steering fluid, it may be low. This will cause a short-lived whining noise on startup. If it’s not low, you may try having the power steering fluid flushed.
When do you turn the steering wheel does the noise go away?
Generally, the noise is worse when you turn the steering wheel and goes away once you drive off. The power steering makes an unmistakable noise that the experienced mechanics can distinguish in a matter of seconds. The noise is very unique and no other component in your car will make similar noise to the power steering pump.
Why is my power steering so low after starting the car?
Could be related to the alternator, which works harder for a minute after starting. It can be heard outside the car. It doesn’t exactly match the speed of the engine. A good possibility here is fluid cavitation (aeration) in the power steering system. Check the level of your power steering fluid, it may be low.
Why does my power steering only work when its cold?
As temperatures dip into the -30°C range, conventional power steering fluids become all but useless. At best, they flow poorly in winter and starve the power steering pump of lubrication at start-up. That growling noise you hear after a cold start is the power steering pump running dry.
Why does power steering growl when cold?
That growling noise you hear after a cold start is the power steering pump running dry. At worst, the power steering oil can be completely frozen and the result can be the fiasco described above. Our synthetic power steering fluids flow below -50°C, so even in the -40s, your steering pump receives fast oil circulation and disasters like blown power steering hoses are averted.
Does cold affect the power steering?
Power steering fluid becomes more viscous in very cold temperatures, and doesn’t flow as well as it normally would. Some vehicle systems require a bit of time for the fluid to warm up. Be sure the power steering fluid is completely up to the full line. If not, add fluid. Proper fluid levels are particularly important in cold weather.
What are the symptoms of a bad power steering pump?
Stiff steering in cold weather or while turning at low speeds is a symptom of a bad power-steering pump. Erratic functioning, such as a bit of slippage while turning the wheel, can indicate a bad power-steering pump.
