How to Put on Belts in a BMW 1996 TI

1. Open the hood and locate the belt tensioner for the air conditioner belt. The tensioner is mounted to the front of the engine block between the crankshaft and the a/c compressor. Use the tensioner pulley bolt to loosen the tension from the belt.
2. Position a 3/8-inch drive breaker bar and a metric socket onto the tensioner pulley bolt. Turn the breaker bar in a counter-clockwise motion to loosen the tension from the belt. Pull the belt out from around the tensioner pulley, the a/c pulley and the crankshaft pulley. Remove the belt from the engine well.
3. Locate the serpentine belt tensioner mounted to the front of the engine block on the lower left hand side of the alternator. Use the tensioner pulley bolt to loosen the tension from the belt.
4. Position a 3/8-inch drive breaker bar and a metric socket onto the tensioner pulley bolt. Turn the breaker bar in a counter-clockwise motion to loosen the tension from the belt. Pull the belt off the tensioner pulley and the remaining accessory pulleys. Remove the belt from the engine compartment.
5. Route the new serpentine belt around the accessories exactly as described by the belt routing diagram that is stamped to the top of the fan shroud. Once the belt is inside the accessory pulleys, turn the tensioner counterclockwise with the breaker bar and socket again and slide the belt around the tensioner pulley. Release the breaker bar and remove it from the tensioner.
6. Route the new air conditioner belt around the a/c compressor pulley and the crankshaft pulley. Turn the tensioner counterclockwise with the breaker bar and socket again. Slide the belt around the tensioner pulley and release the breaker bar. Remove the breaker bar from the engine compartment. Look over both belts to ensure they are seated inside of each accessory pulley.
7. Crank the engine for 10 to 15 seconds to completely seat the new belts inside the accessory pulleys. Turn the engine off.
