Finally the new fan belt is installed. You’ll need to slide it over the harmonic balancer and the alternator pulley and then tighten the alternator. To tighten the alternator put a large screwdriver between it and the motor and pull outwards towards the passenger side of the vehicle. This will push the alternator away from the motor and put pressure on the fan belt. A fan belt is tight when it can only be pushed downwards about a fingers width by your hand. Once the belt is tight you can tighten both the bottom and then top bolts on the alternator to lock it into position.
