Hi, I have a 2006 pontiac montana sv6 AWD
Once everything warms up the steering looses power at low rpm and starts making whistling noises around the steering wheel and can also be herd outside the car somewhere.
I have just replaced the power steering pump and flushed the system. I also replaced the belt and tensioner at the same time.
Air has been bled from the system and i have checked everywhere for leaks and cant see any and im not loosing any fluids. But I still have a lack of power and the whistle noise sounds like it is sucking air into the system somewhere...WTF!
I still get some small bubbles coming up in the reservoir even tho i have bled the system soo many times now..
What is going on?
I am at a loss, can someone please help??
Thanks in advance
