Power steering leaks from the cap

You have Air in the Power steering System and it needs to be bleed out, And to do this if you Jack the two front wheels off the ground and Let them Hang free so there is No Load on the steering at all. please put some type of stands under the car, You will need more power steering fluid but before you add this you need to start your Car and turn the steering Wheel Slow from left to Right a few times, You will hear a wearing Notice come from the pump and you will see more fluid come out of the pump as well, that is the air trying to bleed its self out. The fluid coming out will be air rated lots of bubbles in it, Now that you have done this the Noise from the pump should start to go quite at this Point you can start to Add the New power steering fluid slow to the reservoir and keep turning the steering wheel from left to right slow (Never Fast but slow ) Have a lot of rags to clean the Mess. Hope this helps you. :)

to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.

It's probally low on power steering fluid. If you open the hood, look on the left side right over the passenger tire. Theres a resivore there for power steering fluid. Unscrew the cap and wipe the dip stick clean. Then put it back in and pull it back out and see how far up the stick the fluid reaches. Make sure you put it in all the way so you get an accurate reading. If its low, add some until it says full on the dip stick. then put the cover back on, start the van and turn the steering all the way left and then all the way right a few times. The noise should stop as long as that was the problem. Windstars and known for having power steering leaks so I am going to bet that is the noise your hearing. It's a low toned, whining noise if it is low on power steering fluid. Hope that works for you. Good Luck.

The noise is due to air in the power steering system. It will come out once you fix the leak, by setting the fluid level, install the cap and start and rotate the wheel left and right for a minute...shut off and check level again.

IF your unit has POWER steering, it might be low on fluid, check this first. taking off the cap on the power steering unit itself,,,fill it with correct power steering fluid, IF it continues to make this noise, you might need to replace it??

check to see if you have power steering fluid. if your low fill it up. (most cases thats all it is) check around for any leaks or parts to the power steering unit for and damage (hoses, pump, rer, rack and pinion, any seals or such. you might have a leak somewhere. when your looking for leaks fill the res up with power steering fluid. turn the car on. and have someone turn the wheel so get the fluid to build up pressure in the system.

The power steering leak is creating bubbles in your power steering pump which gets strained more when turning, which causes it to be louder when turning. If you know where your leak is, then fix that, then try to bleed your ps system by filling up with the cap off the resevoir and turning the steering wheel max left to max left with trans fluid. if the noise is still there then your ps pump needs to be replaced along with the ps vsv located on the side of the pump.

Could be either a loose belt or you are low on power steering fluid,or the power steering pump could just be worn out.

To find out witch it is,pump or rack and pinion,break loose the presure line on the power steering pump with a wench.Start the car and turn the steering wheel back and forth,you may need to loosen the nut on the power steering hose two or three turns to get the fluid to shoot out.It should come out pretty forceful.If it doesn`t,then replace the pump.If it does come out really powerful,replace the rack and pinion.

Check your power steering fluid level, and system for leaks. May be a bad p/s pump as well. Hope this helps
