I'm trying to figure out what this 'whizzing' sound is. Wondering if anyone has ever heard anything like it?
Best I can describe it's a kind of soft buzzing / whizzing tone, linked directly to engine speed. It's not exactly a whine, at least, I've watched 100 videos demonstrating different whines and none of them sound like what I've got going on.
Doesn't occur when cold. Doesn't start as soon as engine is up to operating temp - takes a bit more driving than that for it to start.
Happens in Park / Neutral and in gear while driving.
I'm hesitant to pull the serpentine belt and eliminate those components since it only occurs when hot, and I don't know if it's OK to startup from hot without the water pump running. I also notice that if the car is sat for only 10 minutes it won't immediately return upon restart, so I don't know if I can get the air tube off, serpentine belt off and airtube back on fast enough to be sure it hasn't just cooled down in that time.
