M103 Belt Squeak

I just got finished replacing the tensioner, fan bearing bracket, tensioner dampener, and belts....



Went for a 30 min drive, and am now getting a very mild squeak from the belt....



I have it tensioned according to spec, so I dont know whats going on....


The new belt is a Continental....

There are other sources for a squeak/squeal. Check the idler pulley, power steering pulley, A/C compressor pulley and air pump pulley.

You say "Belts"?

I thought the M103 had only one belt. Maybe mine is missing one?

greasy fingers

Unless you installed it with white gloves, you got oil/grease on it.. it will go away in a day, or a week, depending on how greasy it is..

Mine has never squeaked, even when I replaced it with a brand new one.....I used a Conti Germany belt.

The new belt squeak will probably go away but in the meantime you can silence it by (with the engine running) touching the drive side belt a few times with a candle. Its an old trick that garages usually charge $20 for.........

Yeah, the squeak went away, now I am having a different problem with the car...



Sounds like there is no oil getting to valve train for the front 2 cylinders...


But thats another thread.
