NOT ENOUGH INFO.
IS IT DIESEL OR PETROL?
WHAT YEAR OF MANUFACTURE?
IN ANY CASE, YOU MAY NOT NEED TO LOOSEN ANY BOLT .
LOOK FOR TENSIONER.
USE RIGHT SIZE SPANNER (BETTER STILL SOCKET AND RACHET)TO LOAD AGAINST WORKING TENSION (BE CAREFUL!!! HIGH RISK OF INJURY) THIS WILL EFFECTIVELY SLACKEN BELT ALLOWIN BELT TO BE SPLIPPED OFF PULLEY.
MEMORISE ROUTE OFBELT BEFORE COMMENCING
