Diagnosing a noise

[RustyMojo]

Hey guys,
So trying to diagnose a noise which appears to be coming from the PAS pump on my 182. But before I go to the time and expense of paying someone to fix or attempting myself. I am chucking this out there for thoughts. Timing belt and dephaser were changed last year. The noise appears to be coming from PAS pulley. So I wonder if it’s on it’s way out. However when looking at the pulley there appears to be a weight or clutch style system on the pulley itself. Which is loose and when moved as per the video creates the noise. I expected the noise to be the belt tensioner pulley. Obviously if I have to replace the pump then I have to replace the AUX belt and therefore tensioner anyway. Any thoughts??

Whip the aux belt off and then see if the noise is there

The AC should do that as it's on a clutch so when you turn the AC on the pump clutch locks up and in turn engages the AC pump

thanks good to know The clutch on the AC is meant to sound like that. It just sounds very much like the noise the car makes when I move it by hand.

That doesn't sound like the noise a failing PAS pump makes.

Certainly sounds like somethings loose though, ive had a number of bolts back themselves out in that area.

To be honest that’s my thought, it’s either a bearing or something loose. He more I look and think the more I’m going to suggest it’s the belt tensioner.
