How do you install drive belt on Infiniti m45?

To install the drive belt on an Infiniti M45, first ensure the engine is off and cool, and then disconnect the negative battery terminal. Remove any components obstructing access to the drive belt, such as the engine cover or air intake duct. Using a wrench or socket, rotate the tensioner pulley to relieve tension on the old belt, then remove it. Finally, route the new belt according to the belt diagram typically found on a label near the engine, ensuring it is properly seated on all pulleys, and then release the tensioner to apply tension to the belt.
