Disco 300tdi aux belt squeak!
glaggs:
Stripped and re-greased the bearing, it was a little dry but no play or anything. The fit of the tensioner pully onto the shaft felt a bit loose though? Sprayed it with Belt treatment spray tonight, squeal gone away for now?

hi guys just reading ur post ? i have a spueal but its more like a chirp ?
but it only happens when driving ? but if i floor it i dont get it ?
so would it be a belt or turbo ??? no probs with power or black smoke just the irratateing noise ..
its on a 1996 300tdi es auto with all the toys ? well they dont all work yet lol . cam belt just done at parkers but so many belts under there ??
glaggs:
Belt spray worked for 24 hrs, squeak (chirp) came back. Fitted new bearing, noise still there! Will try penny trick. Noise goes away if I spray WD40 on belt but comes back as it dries off.

--- Quote from: "karlo" ---Unbolt the tensioner pull it forward place a 1p at 9 'o' clock position and tighten the tensioner back up and you will proberly find it cures your problem.

Try this mate its only a penny and a 15mm socket unhook the belt off the tensioner first though!
Budgie:
If you don't have aircon then: standing by the battery (drivers side wing) look down the line of the drive belt and you'l see if the tensioner pulley is pulling it out a alinement. You can still see it if you have aircon fitted, it's just a bit harder. :wink:
Normally it pulls it towards the radiator and a shim as Karlo described will sort it for good.
After putting a shim in mine it hasn't squeeked in over 5 years!! :D
