Aux drive belt pre tensioner

[~Rob~]

ok, im still doing the aux. drive belt. ive got the old belt and pre tensioner pully off. now putting on the new belt, i cant seem to figure out how to adjust the pre tensioner. it looks as though its fixed and shouldnt move, however its too tight to get the new belt on with out stretching it. will the pre tensioner arm move with a bit of brut force? i dont wanna end up snapping something!

thanks.

Yeah it will move. How i do it is to get the belt pretty much routed except over the tensioner, then use a long bar or screwdriver through the mounting points for the damper and lever the pulley back until i can slip the belt over the pulley.

Unfortunately you won't have this damper as yours is an auto so try using an appropriate sized socket with wrench or spanner on the centre nut of the tensioner.

Shouldn't really have that much trouble, maybe need a longer bar.

i ended up with a 9inch socket wrench on the nut and a 12inch ring spanner on the end of that.
