Right then,1991 celsior,open bonnet and at bumper level in the space back to the radiator,is a bottle with the washer symbol on , it does have a pump and pipes from it,the main filler is up on the inner wing,I dont have headlamp washers,or it seems,a button to operate said pump,and ive never had to top it up,thought maybe it was a back-up tank for the main one,but run it dry today and nothing happened concerning the tank in question, any ideas peeps.
