Hi Patsy

Sounds very much like your P/Steering Fluid is contaminated.

Possibly condensation, or someone is playing tricks on you ?

I had a friend with a BMW, ask me for help, few weeks back.

He had put just a little brake fluid in by mistake, and it gave exactly your problem.

You will have to change the Power Steering Fluid in the system.

Good Luck !

John.

How to replace power steering pump on 1998 Volvo v70


Place the vehicle in park or neutral with the emergency brake. Let the engine idle. Raise the hood and remove the cap on the power steering pump reservoir. The cap will have a plastic dipstick on the end of it. Wipe the dipstick portion with a rag and screw it back down on the reservoir. Unscrew the lid and check the level indicated on a marked scale on the dipstick. The level should read at the top "Hot" mark. Low fluid level will cause the pump to whine. Fill to the appropriate level and listen for noise.
Inspect the condition of the power steering fluid with the cap off the reservoir. It should be translucent red and slightly thick to the touch. Brown, black or sudsy-looking fluid indicates contamination. Power steering fluid that has lost its viscosity (thickness) cannot properly lubricate the seals, bearings and vanes inside the pump, which will cause a high-pitched whine or squealing noise. If the fluid feels gritty between the fingers, it means rust, metal shavings and dirt has entered the reservoir.
Use a slot screwdriver to loosen the low-pressure rubber hose clamp on the bottom side of the power steering pump reservoir. Catch any drippings in a pan. Loosen the high-pressure metallic line nut on the power steering pump body with a fuel line wrench. Let the fluid drain into a pan. Remove the reservoir cap and use a used turkey baster to suck out all of the power steering fluid. Clean the inside of the reservoir with a rag wrapped around a screwdriver.
Reconnect the rubber low-pressure side hose and tighten the clamp with a slot screwdriver. Screw the metallic line nut on by hand and finish tightening it with a fuel line wrench. Fill the reservoir with new (manufacturer's recommended) power steering fluid to the top mark. Start the engine and listen for noise.
Test the tension and condition of the serpentine belt, or the individual power steering belt. The belt should not be cracked or contaminated with oil or power steering fluid. Clean the belt with alcohol. Adjust the (individual) belt for tension, using an end wrench to loosen the adjusting bolt, and a socket and wrench to slightly loosen the pump mounting bolts. Pry the pump outward with a screwdriver to tighten the slack in the belt. Tighten the adjusting bolt with an end wrench. Tighten the mounting bolts with a socket and wrench.

Powersteering milky in 02 Lincoln


Time to change the power steering fluid. Some cars use power steering fluid, while other cars use transmission fluid. Do not use the wrong fluid in your car or you will have even bigger problems.

I just recently replaced the power steering pump in my car after that we bleed the line and everything seemed fine the next day power steering fluid was spewing out the cap and I can't figure out why now...


there is still air in the system-jack the front of the car off the ground turn the key just until steering unlocks and turn the steering wheel completly side to side at least a dozen times-watch the fluid level it most not run out of the reservoir or it will suck more air into system and continue to foam-cheers Denny

When your power steering pump goes out does it lock up your steering wheel


I doubt it.
Usually when the pump fails it smokes the belt.
If the steering wheel will not turn and the fluid is contaminated, I would say the problem is the gear box or rack and pinion depending on the make model and year.

What would cause power steering fluid turn milky in 2000 chrysler 300?


The power steering is a sealed system. No way coolant could get in there. It might be contaminated by moisture from the air though. So you could suction it out (a turkey baster works great), and replace with clean fluid.
Wasw the engine overheating from low coolant level? Hopefully, thats all it was. Keep it full!

2006 ford focus power steering whine and foming


I have a 06 SES ZX4, same foaming and whining, burped fluid out the cap, progressively worsening in the cold weather. After reading several blogs, found the Ford TSB 08-18-9, and looked at my reservoir O-rings. The outboard ring looked bad, inboard was visibly OK. Replaced both, fixed my problem (Oreilly Auto Parts). Another blogger said he found a filter in his reservoir, mine did not have one. Also, fluid is dark, will be flushing very soon. Car has 130K miles.

that is signs of a leak
