Thread: 1995 D1 300Tdi Serpetine Belt

Hi Matey,
Don’t know about vin#s or which belt sizes suit... but squealing belts I’ve had before... especially when fitting new belts. What happens is as your old belt wears and belt grit and road grime get packed into the grooves of the pulleys so tight that it goes hard and glassy. When you fit a new belt it won’t seat properly and squeals like crazy. The best solution is to remove the pulleys and with the pointed tip of an old knife scratch out the glassy grit (tedious) in the bottom of the grooves. Then give it a good wire brushing with a wire wheel in a bench grinder or drill. No more squealing!!!

G'day Les

Really apreciate your Info mate. I have noticed ALOT of black grim stuck in between the little grooves of the pulley. As soon as i get some time i will take them off and give them a good clean.
