Hello all,

I'm trying to find what's causing this sound from the front of my engine, it's sort of a ticking but increases with acceleration. So far I've changed out the belt, idle puller, tension pulley and drive pulley but the sound still appears. I'm thinking crankshaft pulley area or even the radiator? I've also attempted to use the funnel trick to pinpoint the sound but that seems to work best with finding vacuum leaks...

I'm la bit lost and need some direction if you all could help? Engine is the M272 3.0 V6 from 2008.

Thanks a ton in advance! Attached is a video of it.

Take the belt off, start the car. If the noise is still there, you got a problem.
