How do you fit a fan belt on a 307?

To fit a fan belt on a Peugeot 307, first, ensure the engine is off and cool. Loosen the tensioner pulley using a wrench to relieve tension on the old belt, then remove it. Position the new belt according to the routing diagram usually found in the engine bay, ensuring it fits snugly around all pulleys. Finally, re-tighten the tensioner to secure the belt in place and check for proper alignment before starting the engine.
