Question 1

How to replace the alternator (LF1/LLT) on Cadillac CTS?

Accepted Answer

The negative Battery Cable requires disconnection before performing generator (LF1/LLT) replacement. First detach the generator Drive Belt and subsequently lift and support the vehicle. Remove the front air deflector afterward disconnect the electrical connector that connects to the generator. You need to transfer the protective boot away from the generator output bat terminal location to work on it. Then unfasten the generator output bat terminal nut and remove the positive battery lead from the generator. Lower the vehicle and remove the lower bolts of the generator before using the torque wrench to eliminate the upper bolt to extract the generator from the engine. Installation requires placing the generator back onto the engine followed by a 50 nm (37 lb ft) torque on the generator upper bolt. After lifting the vehicle for support reinstall the generator lower bolts while torquing them to 50 nm (37 lb ft). Reinstall the bat terminal boot while securing the generator's positive lead and bat terminal with a nut tightened to 13 nm (115 lb in). Begin by connecting the electrical connector to the generator but before moving on reinstall the front air deflector and lower the vehicle while also installing the Drive Belt to the generator. As the last step replace the battery negative cable.

How to replace the alternator (LC3) on Cadillac XLR?

Accepted Answer

The first step to replace the generator (LC3) demands the removal of the generator Drive Belt's installation. First disconnect the negative Battery Cable and use cooling system draining and filling procedure (GE 47716) to drain the cooling system. The process begins with front suspension crossmember removal before disconnecting the coolant hose between generator and port using generator coolant hose assembly bolt removal. Remove the generator electrical connector before you detach the starter cable terminal by moving the boot back and extracting the starter cable nut and disassembling the terminal from its stud. The process starts with removing the upper generator bolt then the idler pulley thru-bolt and idler pulley nut before moving to the idler pulley assembly and generator. Place the generator into position then fasten the upper bolt with a torque setting of 50 nm (37 lb ft). First install the idler pulley assembly along with its bolt before tightening the nut and bolt to 50 nm (37 lb ft). Fasten the starter cable terminal to the generator stud then apply torque of 20 nm (15 lb ft) to the starter cable nut before putting the boot into position on the stud. Secure the generator coolant hose assembly using the bolt before tightening to 27 nm (20 lb ft). Afterward, connect the generator electrical connector. Put back the front suspension crossmember while filling the cooling system and reconnecting the negative Battery Cable followed by generator Drive Belt installation.
