How do you change citroen berlingo fan belt?

To change the fan belt on a Citroën Berlingo, start by disconnecting the battery for safety. Remove any components obstructing access to the belt, such as the engine cover. Loosen the tensioner pulley using a wrench or socket to relieve tension on the belt, then slide the old belt off. Install the new belt by following the proper routing diagram, re-tension the pulley, and reassemble any components you removed. Finally, reconnect the battery and start the engine to ensure proper operation.
