Okay, I've narrowed down the whine in the engine...it's either the alternator, the tensioner or the idler pully...and I'm leaning toward the tensioner or idler pully, since that's where the sound seems the louded.
I might just change them all...they're all original with 157,000 miles.
Any tricks or hints on the idler pully? Looks like I have to pull the engine mount to do that job.
I can do the alternator and tensioner together. Part's aren't very expensive.
And...what does the idler pully DO?
Thanks.
