z19dth alternator tensioner chirp

[unreal_event_horizon]

Hi all,
Altenator Belt seems to make a chirp noise at idle when the engine was warm, not heard when driving and if I raise the revs to just above idle it goes away, I changed the belt yesterday and the exact same sound is there, I inspected the tensioners but the tensioner that leans on the belt I found hard to rotate, is this normal?

Thanks in advance
Dave

Thanks

Should be freely spinning when not pushing against the belt...

How was the clutch on the alternator pulley?

you have me there lee, is there a centrifugal clutch within this pully?? , i could barely get my spanner and hands up there to lock it out with an alan key (slipped an alan key in the two holes, had no blasted drill bit to do same)

it was a bit hard to rotate, sprayed some penetrative release oil (wd40 equivalent but i find it better), seemed to move a bit more freely but maybe i didn't use enough.

oh by the way lee, how are you man, long time since i spoke to you, are all your astra's gone? including, i could have your significant others name wrong..Lauras?

sold my astra and went to northern ireland for my vectra cdti. very happy with her, she has a few bits i want changed, would love a vxr front bumper

You are correct with my wifes name

Yeah all Astra's gone and down to a Saxo (Just a run about), Corsa CDTi and my Signum CDTi

The alternator pulley should rotate one way only and it be quite firm to turn,

Sorry to ask a daft q, but you certain its the aux/drive belt and not cambelt / waterpump?

Got the timing belt and waterpump done at 90k , she has 110k on it now, all opel/vaux parts, pump should hardly fail that soon! I hope! Lol

Agree it shouldnt mate.. Just wanted to check - seen too many failed pumps.

You can of course run the car with the aux belt off to 100% check for a min...

Just out of curiosity how long can I run her? And how many starts would I get before the bat gets shot
