thanks all for your help and advice....i put on the new lower pulley that i had to order that came in this morning and turns out that was the problem....no more noise....it's weird though....tensioner pulley that i first replaced was $21.....bottom pulley was over $60
It's a V6.....I have not tried belt dressing I will replace the pulley I have off of it now then try the belt dressing.....if it is the alternator how can I tell if that is what's making the sound if all the electrical system is acting normal?
I have an 06 Runner...I have a whining noise from engine compartment..does it in park and neutral. I'm pretty sure it's not tranny, power steering, or water pump related. i checked out other posts and replaced the tensioner pulley...didn't work...still had the noise. I pulled the other...
