Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello Im Chris and I will assist you.
Can you look into your power steering reservoir and tell me if you see little bubbles?
No bubbles and he used an Acura pump already. Does the whine get louder with engine speed?
Acura makes an updated inlet O-ring for that pump that is orange. That usually takes care of the problem. Did he install the orange O-ring?
Are you there Mike?
There are a few other things that can make these pumps wine. Try replacing the Feed hose between the pump and power steering tank as well as the tank itself. If the hose gets hard with age it can suck air into the system and cause the pump to wine. There is a screen in the bottom of the tank that can get plugged and cause the pump to wine as well. Also the fan belt tensioner pulleys can wine as well as the alternator. It would be a good idea to try a mechanic stethascope to try to pinpoint the sound if this has not already been tried.
