Sounds like the system is getting air in it from somewhere. Check to see if you see fluid leaking from any point of the system.
on a1995 ford windstar was running fine until power steering fluid leaked and foam up on to the engine
One or two thing can be happen I have 1999 lincoln it can be steering pump but for sure it's the rack opinion My lincoln dose the same
It really depends on the vehicle you put it in. ATF can sometimes "foam up" and cause air to get in the system. (PTB) To clarify: you may use ATF in some power steering, but do not even think about using power steering fluid in your transmission.
Frankly, any parts store power steering fluid will work fine in this application. GM uses robust power steering pumps, and they do not require any special fluid. However, do not use transmission fluid, it does not have the appropriate anti-foam additives, and can cause pump cavitation, which will damage the pump.
Passenger side fender, 2 tubes run feont to back. The high side is on top the low side is right under it. They both have foam on them. If you feel the low side it has 2sections of foam on it about 8" apart. If you squeeze it you will feel the connections inside the foam. This section is where your orifice tube will be.
I don't know what you mean by " specs ' for p\s fluid. If you are talking about what to use,I suggest Power steering fluid. You can substitute trany fluid,but it has a tendency to foam. In " normal " steering systems this isn't awful,but in a rack and pinion system it could cause problems.
It could mean it's time to change the fluid in the power steering system. This is best done by a professional shop that can properly flush and purge the system. I would advise spending a few dollars extra for SYNTHETIC power steering fluid as it lasts longer. Your vehicle should never "use up" power steering fluid. If it's low you have a leak somewhere and it needs to be addressed ASAP. If you let the power steering pump run with low fluid you will ruin the pump very quickly.
A metal inner surrounded by foam and plastic or leather.
There is no known bleed port.The foam [frawth]will dissapate. Most of the time you only need to "let it set awhile". Most likely by the time you came in to ask your question the foam trapped in the system has mostly dissapated. by moving the wheel from side to the other side a few times will get all the air out. dont over fill the tank since it will spill out and it needs the extra space. you may have gotten the oil low and need more to stop the foam.
Water in the oil! lack of power and foam on the dip stick or white smoke: Head gasket?No loss of power lots of foam, gets hot rainbow on the water surface: crack in the engine or head? ouch!
I had this on my 1994 Ford Fairmont (Australian) - turns out the horn pad in the center of the steering wheel is heald out from the contacts by some soft foam rubber, which breaks down after a while, so that the contacts are always touching. Step 1. pull the plugs out from the horns themselves to shut the thing up! Step 2. Get a new horn 'pad' (center of steering wheel) to replace the old one. Hope this helps.
On a 1996 Taurus, it's the smaller line located above the passenger fenderwell right below the low pressure line (hidden by the larger line). It has a foam wrap around the junction (2 nuts) that can be separated and the orifice tube removed.
