Question Engine Howl AUII

Help! My 6cyl AUII engine is making a high pitch howl and i dont know how to fix it. First i thought it was the fanbelt slipping so i used some soap on the belt. That only worked for a little while. So i Bought a new BOSCH belt and it still makes the noise. Please help. I dont want to take it to the mechanic because they'll just rip me off. Has anyone had this problem?

It could be the bearings on the a/c compressor, the water pump, the alternator etc. Take it to a mechanic - it is almost un-possible to diagnose a noise like that over the internet.

its probably the top tensioner bearing which u cant replace unless you buy a a whole pulley! 26$ part from wreckers and it stopped my whinning noise. Could be your problem sound like it, could be any of them pulley bearings who knows listen closely if u can.

get a screwdriver and hold the handle to your ear then use the pointy end to rest on the NON MOVING parts of the pulleys.. if it sounds like its scraping/grinding/not good then thats the culprit
if its a huming like noise.. its fine

Cut a piece off your garden hose and use it like a stethescope to channel the noise.
Listen closely to each moving object.
Dont recommend the screwdriver technique. I know of someone who ended up with one through his neck.
Cheers
