• Q: How to replace the alternator on 2004 Chevrolet Trailblazer?

  A: Disconnection of the negative Battery Cable and belt removal stands as the first step for replacing the Alternator. Drop the battery positive cable nut from the generator followed by the a/c line mounting bracket bolt at the engine lift hook. Start by removing both right engine lift hook bolts until you can take off the lift hook. Remove the generator first by unbolting the three attached generator mounting points before extracting it. Installation requires the generator to be attached using the 3 bolts while torquing each to 50 n.m (37 lb ft). Secure the positive Battery Cable to the generator by tightening its nut to 9 n.m using 80 lb in torque settings. Screw in the engine lift hook while tightening 2 bolts to 50 n.m (37 lb in) torque specification. Fix the a/c line bracket to the lift hook by threading the bolt until it reaches 10 n.m torque (89 lb in of torque). Once everything is ready, install the Drive Belt followed by reconnecting the negative cable of the battery.
