Q:
How to remove and install an alternator in a Cadillac Escalade? Posted by Customer
A:
Disconnect the cable from the negative battery terminal. Remove the air intake duct. Remove the drivebelt. On 6.0L models, remove the engine cover. Peel back the weather boot from the B+ terminal, remove the nut and disconnect the battery cable from the alternator. Disconnect the electrical connector from the alternator. Remove the two alternator mounting bolts. To detach the alternator from 6.0L models, remove these two bolts. Remove the alternator. Installation is the reverse of removal. Be sure to tighten the alternator mounting bolts.
