• Q: How to replace the alternator (LY7) without direct fuel injection on 2008 Cadillac CTS?

  A: Begin generator (LY7) replacement by disconnecting the battery negative cable first before proceeding. Next remove the Drive Belt from the generator. First lift and support the vehicle before removing the electrical connector from the generator. Access the generator output bat terminal by moving the protective boot aside then unscrew the generator output bat terminal nut until the battery positive lead disconnects from the generator. Start by removing the lower bolts from the generator then lower the vehicle before unscrewing the upper bolt to pull out the generator from the engine. The generator needs to be placed onto its designated spot on the engine where it will be secured through the upper bolt installation mechanism. Secure the vehicle position with support tools before tightening lower bolts to 50 n.m (37 lb ft). Secure the generator bat terminal nut with 13 n.m (115 lb in) torque while connecting the battery positive lead and install the bat terminal boot. Start by connecting the electrical connector to the generator, then lower the vehicle to align the generator Drive Belt. After that, reattach the battery negative cable.
