annoying squeak
 

my shed is playing up , , I'm just throwing this out for you guys for your opinions
I'm getting an annoying belt squeak , replaced. new serp belt and tensioner,. still squeaking,
removed AC belt , fired it up , still squeaking so its not ac belt or pulley side
checked WP seems ok no play ( 3 months old)
alternator , spins free, no play (1 year old)
PS pump , seems a bit notchy when you turn it but no play but sounds noisier on rotation than the others (17 years and 160k miles)
you can start it up , its quiet. rev to 2k , it starts,. then it squeals from then on
going to go and try firing it up after work (which will annoy neighbours. as it will be 06:30 , and ive got a X pipe on it :)
ill turn the wheel L to R to see if it alters
ive sprayed wd 40on the belt and it stopped squealing , but ive tried 3 different serp belts by 3 different companies and I'm certain its not belt or tensioner,
ideas?

Usually you spray water not wd40 to the belt. And if noise goes away it means you have a misaligned pulley somewhere.

I have been playing today, :)
I had to get the beast . due to other cars battery failing on me, cos its bloody cold here in the uk
drove the X the noise is getting loud :)
one of the lads on the FB page suggested, the lucas stop leak, and as I had a bottle of this, I sucked some of the old fluid out, which looked like babies yellow, (if your a parent you will know this) I had some ring rld04 in to diagnose oil leak
so threw a full bottle in
ive only drove the car maybe 10 miles, but I "seems" to have quietened down?
just waiting for my indy to drag it in, then they might haha, be able to diagnose it

The sound you describe sounds more like "squeal" than "squeak". And the usual culprit is bearing/seal on the water pump.

Could also be bearings for tensioner pulleys. An automotive stethoscope is the best way to pin point where the noise is coming from.

Yes any bearing. You can use a long long socket extension as a red neck stethoscope

its looking like it was the PS pump , I had some lucas stop leak, removed full, reservoir and put in , that, squeak 99% stopped,
going to get another pump if it starts squealing again ,and a new reservoir, as mines original 17 years and 160k miles old, here is what my fluid looked like , so its either the pump that's nackered or the fluid that's causing the squeak, there is a slight red tinge to the fluid , but most is the rld4 detection dye, which has been if for over 6 months
might get away with a flush , or new pump , no idea
