I want to change the ribbed alternator drive belt on my 1600 Sigma because it sounds like an aviary full of canaries on starting from cold and particles of the existing belt can be found stuck to the underside of the bonnet. Has anyone done this and, if so, how is the belt tensioned?
How many miles have you done?
You should not have particles of rubber stuck to the underside of the bonnet. I would investigate to see if something is out of alignment or possibly a damaged pulley before replacing the belt.
