[Drawl21]

Hi all,how do i adjust the above,its very loose,i've had a look around the forum and can't seem to find any info,i believe its adjusted with shims? but i've no idea how,any help would be much appreciated,it's a 1987 1.6d cs,thanks

The shims are between the two cheeks of the water pump pulley.

thanks,ah right,think i get it now,remove shim/shims so it lifts the belt from the grove and tightens it,i'm a new owner its all a bit new to me,the belt from crank to waterpump is a lot thinner than the alternator belt and so sits a lot lower in the pulley,wrong belt maybe?,its an import and only done 67000 km,there's no part number on the old belt,i've looked on a few parts suppliers and there seems to be a few different lengths,don't suppose anybody has a part number for the correct belt please?,thanks in advance Dave

Its a horrid job, good luck!
