Name that squeel

right , almost had enough now  :evil:
i replaced the rad, and water pump the other day along with the P gasket, no problems there. cleaned the intercooler lovely black gunk came out. blanked off the egr and replaced the top hose with a non egr type. definately more power now.
but and there always is, on replacing the aux belt she has developed a very high pitched squeel and sort of ticking noise.
if i spray wd40 on the pulleys it stops for a while then returns. it seem to be from the ribbed side of the belt and predominately from the water pump pulley is causing the noise.
i thought it might have been the pump but then appling wd40 to the pulley itself it stops. 10 minutes later its back. it gets worse on acceleration. it sounds like a slipping belt at times ( the squeel) but then stops and becomes a frantic tapping / ticking noise.
not good when you arrive home off nights at 6, neighbours must love me  :twisted:

does any of this make sense to anyone or is it back to the garage and more money  :evil:

thanks for taking time to read this guys but i've nearly had enough now

Paul:
Hi Jim,

When I had belt noise I replaced the serpentine belt and gave the pulleys a good wash down with hot soapy water...  never heard a thing after that.

K9Jim:
dude lovin your style, thats my next port of call then. thanks for the quick reply.
anyone else ?

ChrisW:
Sounds like the bearing has gone in the aux belt tensioner - you can pick up a bearing kit off that auction site for about a tenner or a new tensioner for about 40-50 quid.
Replacing the bearing is a bit fiddly as the circlip is a plain one with no eyes to remove it.

beast5680:
check the belt is running square on the pulleys, when my power steering pump shaft started to go it made the pulley run out of line making the belt squeal like a banshee
