1. Do NOT start the engine until the system is fully bled, doing so may cause damage to the power steering components. Pump internals are metal to metal so any air in the system can cause metal to metal contact and resulting damage.
2. Raise the front wheels off the ground
3. Turn the steering wheel fully to the RIGHT
4. Fill the reservoir to the "full cold" level & leave the cap off. Use only XADO CHF or Honda PSF-S fluid. Do NOT use automatic transmission fluid as transmission fluid does not contain the same friction inhibitors/additives and tends to breakdown and overheat. The use of transmission fluid will VOID the warranty
5. With an assistant checking the fluid level, turn the steering wheel slowly and smoothly lock to lock until the level drops in the reservoir. If the fluid level does not drop no fluid has moved through the system, this indicates an air bubble in the reservoir or pump. Until this bubble passes no fluid will circulate through the system. ? On systems with coolers you may need to cycle in excess of 40 times ? Do NOT turn the steering wheel fast as this will cause the fluid to overflow the reservoir, trapped air may cause the fluid to overflow. Thoroughly clean any spilled fluid so you can check later for any leaks
6. Check the fluid constantly to ensure proper level and that no bubbles exist. ? If you see any signs of bubbles recheck all hose connections then repeat the steps above. ? The fluid level should be steady
7. Disable the engine from starting ? Crank the engine several revolutions, if the fluid level drops there is compressed air trapped in the system, repeat the above steps until the fluid level remains stable. ? If the fluid foams while cranking wait at least 10 minutes or more until dispersed air has time to accumulate and purge through the reservoir.
8. Continue to repeat the steps above until the fluid level remains constant and no air bubbles are visible.
9. Now start the engine and check that the fluid remains at level and stable
10. Reinstall the reservoir cap
11. Return wheels to centre and lower wheels to the ground
12. Run the engine for two minutes and turn steering wheel in both directions
13. Do NOT hold the steering wheel against the stops
14. Verify the following conditions ? The steering is smooth ? Noiseless operation ? Proper fluid level ? No leaks ? Proper fluid condition ? No bubbles, foaming or fluid discolouration
15. If all of the above conditions are satisfied the bleeding procedure is complete
16. If any problem exists then turn off the engine and see special conditions below Special Conditions If you experience any of the conditions listed below then there is still air in the system. ? Foam or bubbles in the fluid ? Power steering fluid should not rise in the reservoir when the engine is turned off, if this occurs there is air trapped in the system ? Be aware of any periodic bubbles that could indicate a loose connection, leaky o-ring or a bad flare seat in either the pressure or return hose ? Discoloured fluid (milky, opaque or light tan colour) If you have any questions regarding this procedure please contact us before you install the replacement power steering pump that you have purchased from us, we will be happy to help you.
Check up the hydraulic power steering pump. See picture below for 1.6, 1.8 liters Audi (4 cyl.) engines:
If you find leaks and noise when runing, the hydraulic vane type pump is damaged. The pump inputs air inside and mix air with oil resulting foam. Therefore fluid volume inside steering instalation rises. Then pressure overflows oil from the reservoir. You need repair or replace hydraulic vane type steering pump.
Air is getting into the fluid. This is usually from a bad o-ring on the pump where the return hose from the reservoir connects. Replace that hose and the o-ring. You don't say what year, some had a recall for this problem.
The power steering reservoir (I believe) is on the drivers side just behind the headlight. about mid-way down the side of the reservoir are a high and low mark. The reservoir should be just at or below the high mark when the vehicle is off. ONLY USE HONDA POWER STEERING FLUID. There are certain conditioners and additives in the Honda fluid that keep seals in the system in good condition. Using a generic/aftermarket fluid will cause the seals to shrink and the system will likely develop leaks.
It sounds as if you have a volume of air in your power steering system. This is causing the bubbling and also some of the noise you might be generating when you turn the wheels hard right or hard left. This air might have been introduced if your old belt was slipping so much that the pump was essentially not operating and fluid wasn't regularly circulating throughout the system. Another, more expensive possibility is that your old belt was slipping because the power steering pump itself was starting to fail, and the new, grippier belt is turning the damaged pump and showing you its lack of functionality.
The first and easiest thing to do would be to bleed the system. Open the hood and take the cover of the power steering fluid reservoir. With the engine off but the steering wheel unlocked, slowly turn the steering wheel all the way to one side and then to the other. Repeat this several times while watching the power steering reservoir. Is the fluid bubbling? If so, good, you're purging air out of your system. In general, this is easier with the front wheels off the ground, but that is not absolutely necessary (if you have strong arms).
Once you have purged the system, put the cap back on the power steering reservoir, topping it off if the fluid level has dropped to the fill mark. Now, restart your car and observe the power steering pump. Does it seem to be operating quietly and smoothly? If you touch the pump 1-2 minutes after the engine has been running, is it hot to the touch? It will probably be warm, but _hot_ is an indication that something is overheating inside the pump. Is the power steering fluid very dark colored or does it smell burned? This is also a sign that the fluid should be changed ASAP and that some internal damage may have occurred. Burned fluid isn't necessarily an indication that your power steering pump is bad. However, if after changing your PS fluid the new fluid quickly becomes dark and starts smelling burned, then it's probably time to start saving money for a new or rebuilt power steering pump.
You should never have to replace the power steering fluid in your vehicle. But if you still want to, the best way is to use a turkey baster and pull as much fluid out of the reservoir and into a suitable container, then refill the power steering reservoir.
The Power Steering Reservoir is foaming the fluid, causing the noise. Honda's solution is to replace the reservoir with a new one that does not foam the fluid. You can do the same by punching a hole in the screen at the bottom of the reservoir. Then idle the car for a moment or two and flush the fluid. WalMart PS fluid will work fine.

Check the level in the power steering fluid reservoir. You most likely need a top up. The noise is caused by the pump effectively pumping air through the system. Top up to the level marked in the reservoir then turn on the engine and move the steering wheel around for a wile then turn off an re top up to the level marked in the reservoir and all should then be OK. Make sure you use the correct fluid for the car – usually a Red Dexron Hydraulic Fluid.
