When the car is started in the morning and the engine is cold, the steering make noise when it is turned. When the engine gets warmed up, the noise stops. No noise when the steering wheel is turned either left or right.

    try getting the fluid changed. when old fluid is cold, it does not circulate well. a good flush may solve your problem. if not, you may be replacing the pump.

    There is a Acura TSB on this. There is an updated "o" ring for inlet pipe. What is happening is air is being sucked into the pump when the ring is cold. The ring is less the $1.00 and it takes about 15 mins to install.
    As follows;
    Under REPAIR PROCEDURE, a note was added to check the color of the inlet joint O-ring if the vehicle was previously repaired under S/B 08-016
    A moan or whine is heard when turning the steering wheel when the engine is cold. There may be air bubbles or foam in the power steering reservoir. The noise usually goes away when the engine warms up.
    Air is entering the power steering pump through the inlet joint O-ring. This causes bubbles to form in the power steering fluid, leading to reduced pump performance.

    Replace the O-ring on the power steering pump inlet joint.

    hello- is it hard to replace? can I do it myself? how do you do it? where can I buy it? do I need to flush and replace the power steering fluid when I do it? thank you!
