2009 Yaris rattling/growling from engine bay
Hey YW, my 2009 Yaris sedan has 110k miles on the odo. I noticed a rattling/growling noise when I parked it last night. Took a short video of it. is this timing chain rattle?

Is it the original water pump? I'd pop the belt off and check the water pump first. Also not sure if your model had them but I've seen 2 Avensis models where the over unning clutch on the alternator has gone bad and started making noise. Not sure if your particular Yaris model has one or not. My 06 doesn't.

I replaced the water pump about 40k miles ago, but it's possible it could have gone again. Hadn't heard of that screwdriver trick before, I'll see if I can find one that's metal through and through at harbor freight. Thanks for the suggestions guys.

I'd pop the belt off and have a feel of all the driven accessories. Hopefully it isn't the supercharger.

Definitely sounds like the supercharger... Noise is getting more noticeable as well. Blitz USA still lists the 1NZ supercharger on their site. Maybe they can help me out.
