Manual-Mecanica Response on the subject Urgent doubt
In some cases it has a screw that loosen or squeezes the belt either by moving the compressor or pressing a pulley ... if the belt broke you, take it to give you an equal .. and if it is not broken it was that it stretch and must have a screw that squeezes or loosening as I told you .. if it is loose it means that it is not bad time to change it
