    Q:
    How to replace the alternator on Chevrolet Impala? Posted by Customer
    A:
    Begin the generator replacement process by disconnecting the negative Battery Cable while also removing the engine sight shield. Disassemble the Drive Belt and detach the generator electrical connector before proceeding. To access the generator output bat terminal position its protective boot aside then take off both the generator output bat terminal nut and positive battery lead. Pull out the generator bolts followed by the removal of the generator. Affix the generator along with its bolts while tightening them to 50 n.m (37 lb ft). Reconnect the positive battery lead to the generator output bat terminal while tightening the generator output bat terminal nut to 20 n.m (15 lb ft). Place the protective boot onto the generator output bat terminal while attaching the generator electrical connector and Drive Belt and engine sight shield, and conclude with reattachment of the negative Battery Cable.
