I am trying my first time to flush the power steering fluid on my 2003 Infinity Q45.
This is the procedure I have followed:
Disconnect return hose to the power steering fluid tank.
Drain power steering fluid from tank.
Refill tank with new power steering fluid. I use AMSOIL ATFQT. It is recommended on their website.
Turn steering wheel very fast and lightly touch each stop.
Refill tank as necessary.
Stop when clean fluid comes out of return hose.
One problem I made was one time I emptied the tank on accident after turning the wheel too many times, so I just refilled and keep going.
After this I started the car and the pump makes a lot of noise, so I turn it off.
The two problem I made was that now a bunch of bubbly ATF is coming out of the tank.
So now I also notice in the bottom of the manual it states to bleed the system using this procedure:
Turn wheel back and forth quickly and lightly touch each stop, watching fluid level. So I keep track and the fluid level does drop lower than the tank cap can measure, so I put more fluid in until it is in the cold range and not lowering any more.
I turn the engine on and the pump makes a bunch of noise. I turn the engine off and the tank is overflowing again with bubbles.
After some time the bubbles go away and the oil returns to prvious level.
I am wondering if Amsoil recommends the wrong fluid or if I am doing something wrong or maybe I break something?
