Hello, searched many related links but didnt hear anything about this.
Accelerating half throttle or more in each gear after 3300 rpm I begin to hear a whine akin to a turbo or moreso like a whiney powersteering pump thats empty.
Checked the fluid its fine done it since ive owned it 6 mo ago 150000 to now 160000 03 esv.
Any ideas?

Has the tensioner pulley been replaced lately?

The idler pulley can also cause a whine

Check the power steering tranny fluid both can also cause a whine

Hi thanks I checked trans and ps.
Good point on the pully bearings though.
Ill have to take the belts off and check.
I did have some nearly annoying belt noise in the cooler months but its quite now i think it was the ac belt.
Thanks for that. Ill get back to you with results.

If you haven't changed the a/c belt I suggest changing it ASAP
If it snaps it can damage the tranny cooler lines just below the a/c
Trust me you don't want to have to replace those(NOT CHEAP)
