Unhappy Air bubbles in Power Steering Reservoir

Hello,

I have an 8th Gen 4 Door EX-L automatic with about 90k miles on it.

Searched the forum for power steering issues and I found the o-ring fix for the 7th gen, but not the 8th gen.

I cannot see any leaks. My car only makes a loud reving sound when I turn Left only and straighten the wheel the noise goes away.

Popped the hood open with car running and removed the cap to the power steering reservoir and see air bubbles.


Any idea what the fix should be?


Replace power steering pump? Replace hose? Do the 7th gen o ring thing?

I read others replaced the rack for a whole lot of money.

Try Lucas power steering stop leak. I had a range rover that was literally pissing out power steering fluid and this stuff stopped the leak.

OK, you say you don't "see any leaks", but are you in fact losing power steering fluid?

Air bubbles are normal if the power steering fluid level is within low/high levels. It is a pump, after all, and pushing that fluid around a non air-tight system will mean there will be a few bubbles. What you don't want is frothing. If you have a frothy mixture when you remove the little reservoir cap for a second or two to look inside while the car is running, then that means you are getting way too much air in there.

But the issue here is a groaning noise, is that correct? Only when turning left?

A new O-ring is under 2 bucks, and will take you about 5 minutes to swap. When is the last time you changed out your power steering fluid? If you did, did you use Honda PS fluid or which brand/type?

Hey folks.

Not losing fluid. reservoir level has been in the middle of max and low.

I do honda power steering fluid. I could top it off to max and see if it drops over period of time.

No foaming in the tank when the engine is running.

I hear about the o ring. Anyone got a link to the o -ring repair?

I watched a video of a complete power steering over haul. not sure if that what you folks are implying on need to do.


i think this is what you guys are referring too.

I saw the 7th gen o ring fix, but didn't think that would be the same for the 8th gen?

Never changed PS fluid.

Changed o-ring today and the noise went away! Works on the 8th Gen I4 Honda accord.


emptied the reservoir tank and disconnect the hose from it to clean it out.

Removed the 10 mm bolt on the hose on the front of the power steering pump.

The original o-ring was black and the new one was orange.

Turn wheel left to right and back a couple times until the noise went away. turned off car and checked for fluid leaks and filled the tank between min and full.

Sweet. I don't have this issue but if it pops up now I'll know what to do. Did you replace the PS fluid that you took out with new fluid or just put it back in after changing the o-ring?

Do you still see bubbles in the reservoir after replacing the o-ring?

Honda changed the color to orange for the new improved O-ring to differentiate from the old black one. PS fluid should be changed 25K, from AAA.

I don't believe that is an exact true statement. I believe the 7th gen o-ring is orange in color. It is also mentioned in a TSB.

However, the 8th gen o-ring is still black. The correct part number for the 8th gen is 91345-R70-A11.

I replaced mine about 7-8 months ago because I also experienced foaming in the reservoir. I changed the fluid as well, and now my steering is quiet and no foaming. Check out the part number I posted. It should be about 2 bucks at your local dealer.

You are right, was thinking about the 7th. gen. I stand corrected.
