my alternator tensioner on my 1995 esc cos wont stop squeeking i have changed the belt changed the tensioner for a good second hand one then bought two new beerings and they all get noisey within 5 minutes of running i have run out of ideas now and need help as i am getting some very strange looks when sat in traffic as it is so loud i have taken the air-cn belt off and that makes no differents to the noise and i have bought a snap on stephoscope which i have put on the alternator/waterpump and the power steering pump and they all run quite so the noise is deffinatly comming from this pulley any ideas much appriesiated as i have run out of ideas now cheers

 

may be a long shot.it may not be you tensioner at all,squirt a bit of wd40 directly on to the multy v part of the alternator belt while the engine is running see if clears,had a similar problem and swore it was everything else, turned to be the belt

 

the alternator on an escos is the actual tensioner, is uses a spring loaded self ajusting arm to set the tension. as above, have you swapped the acyual belt as they do go shiny on the multi'v's with age.

 

write thanks for the replies i have put some stuff called belt dressing on the belt and it does make it go quite briethly but then comes strate back the same so i am going to try another new belt from fords this time and see if that cures it i will post the results
