Find the leak and repair it. Could be the pump, hose or the rack and pinion. The foam is from sucking air into the system from being low. Same as the noise.

Spray down pump and hoses with degreaser and wash off. After its dry, use recomended fluid to fill. Start engine and turn steering wheel all the way left, and all the way right a couple of times. This will blead the air from the system. Now shut off and check fluid. Make sure it is full. Now drive the car down the road and make turns, and drive it back and check fluid level. If its still foamy and not leaking fluid, your pump ma be bad.

How do you bleed the air out of the power steering system?


If the pump went dry there is a chance that it was damaged....replace the line, re-fill with the proper power steering fluid to the full mark, cap it, start the car and turn the wheel all the way right, then left a few times to help fill the rack with fluid. check the level and top it off as necessary. drive the car a few miles and re-check the level. Whining after the reservoir is full indicates damage to the pump, steering rack or both.
Good luck

Tip

Sound like your power steering pump is going bad? Not necessarily...


I had a customer that told me their power steering pump was going out. They described the typical power steering whine and difficulty steering. When I went to verify the complaint, I discovered that it didn't whine or have trouble right away. It took a minute or two to actually appear. I had to do some research and what I discovered was that, while a typical vehicle would have the return hose connect directly to the bottom of the reservoir, in the volvo it connects near the top. Inside the reservoir, to keep the fluid from becoming aerated, there is a small, plastic, "L" shaped tube that connects to the p/s return on the INSIDE of the reservoir. In the case of the vehicle I was working on, this tube had popped off causing the fluid to become severely aerated. The air would enter the system (after developing from running for a short bit) causing it to sound like it had a bad pump.

So, if you suspect that the power steering pump is bad, check the fluid level first (as you always should) and examine the condition of it right after running it. The cap might be pressurized and pop off, which is a very good indication of the problem I'm speaking of. The fluid may pour out as well. In any case, if it's foamy, though otherwise at least filled to the minimum line, look inside the reservoir towards the engine side of it where the return line enters to see if you see either a black plastic tube running to the bottom or a beveled, metal tube that has nothing connected. If you check and see the latter, fish around in the reservoir for the plastic tube. You should find it and can likely pop it back on to the return tube. Bleed the system as you normally would and you should find that the problem goes away. Hope that helps!

How to bleed air from power steering 02 kia optima


Make sure there are no leaks in the return hose. If there are leaks in the return line it could be pulling in air and causing the foaming and noise. If there are no leaks you fill the reservoir with power steering fluid and crank the car then turn the steering wheel all the way to the right then all the way to the left a couple of times and that should get rid of all the air in the lines.

Power steering foam


If its foamy than its cavitation. Let it sit overnight and see if it fluid is full in the reservoir. If it is than I would try flushing the power steering fluid. If its low top it off and check for leaks

The oil in my power steering is black how do I change it


First thing you need to do is remove thwe return line from your power steering reservoir. Thats the thing you put the power steering fluid in. Run that hose to a large container where you can catch a lot of fluid in. Now you want to make sure you have your new power steering fluid on hand before you start and another person would be very helpful also. Have your helper start the car and turn the wheel back and forth while you pour power steering fluid in the reservoir. Do not let your power steering fluid run completely out you can ruin your pump and or steering box. Continue to pour in new steering fluid until the fluid coming out of the hose thats in the bucket is clean fluid. Turn vehicle off reconect the hose to the reservoir and top off. With the lid off reservoir start the vehicle back up and turn wheel all the way back and forth many times(do not turn it to its furthest position where it bumps) continue to make sure the fluid level is always full. By turning the wheel back and forth you are bleeding the lines to get all the air out. Do that a few times, refill and put the cap back on. You just changed your power steering fluid. I f your vehicle is old you may want to get new rubber hoses for your power steering system. hoses degrade over time and eventually they start to flake off into your fluid which can damage parts. Always a good idea to replace hoses especially if they are soft.

After I replaced the power steering pump and reservoir on my 2002 Jeep, I still get air in the system. Where could it be coming from?


Your problem could be a pressure side hose that has a rupture that only leaks in extreme conditions. Inspect to replace with new to repair problem. First make sure you have removed the pump caps off of the hose fittings. If ok, it appears you may have a stuck valve in the rack assembly. Replacing the rack should solve your problem. ------- The new pump should be self-bleeding by turning the wheels left and right. Let sit over night to release air bubbles, recheck fluid level.------ Check the tension of the drive belts on the pump, as they may be loose. The power steering pump and reservoir is located on the front of the engine driven by one of the fan belts. There is a removable cap on the top with a dipstick attached. With the engine off, fill this up to the full mark with power steering fluid. Replace the cap, start the engine and check for leaks. On the back of the pump are two hoses either one could be leaking. REPAIR PROCEDURE:
1. Wipe the power steering cap and area free of dirt. Remove the power steering cap.

2. Use a siphon pump to remove as much fluid as possible from the power steering fluid reservoir.

3. With a helper in the vehicle, raise the vehicle on an appropriate hoist.

WARNING :POWER STEERING FLUID, ENGINE PARTS, AND THE EXHAUST SYSTEM MAY BE EXTREMELY HOT IF THE ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES OR POWER STEERING FLUID TO TOUCH HOT EXHAUST MANI FOLD OR CATALYST.
4. Locate the power steering cooler attached to the crossmember support plate. Slide back the clamp and disconnect one of the two power steering return hoses at the power steering oil cooler and drain fluid in an appropriate container.
5. Have the helper turn the steering wheel back and forth quickly several times to force as much fluid as possible from the steering gear.
6. Reconnect the hose at the oil cooler using the original clamp.
7. Lower vehicle so the vehicle tires are not contacting the ground.
9. For proper fluid fill and bleeding air from the power steering system:

a. Fill the power steering reservoir to the top of the fill range using Mopar power steering fluid (ATF+4) p/n 05013458AA.

b. With the engine OFF and the vehicles tires off the ground, slowly turn the steering wheel back and forth (lock to lock) slowly 20 times to force fluid into the steering gear.

c. Fill the power steering reservoir to the top of the fill range.

d. Start engine and let run for a few seconds, then turn oft engine.

e. Check fluid level and add if necessary.

f. Start engine, and slowly turn the steering wheel lightly contacting the left and right stops.

g. Stop the engine and check fluid level. Add fluid if necessary.

h. Lower vehicle, start engine and slowly turn steering wheel lock-to-lock.

I. Stop engine and check fluid level. Add fluid if necessary.

j. If fluid is extremely foamy, allow vehicle to stabilize a few minutes, then repeat steps "i" and "j" until the fluid level remains constant after running the engine and turning the steering wheel from lock to lock.

10. Inform the vehicle owner/operator that a steering vibration may be noted for a few hundred miles until the air is completely removed from the steering system.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Get someone to help you with this. If you start the car with the reservoir half full and slowly turn the steering from left to right lock and back 4 or 5 times it should expel all the air from the system.
Get you helper to add fluid to the reservoir as needed during this process to keep it at least half full.
Top up to correct level when all air is out.
