The most complicated thing I ' ve ever changed in my car has been a cassette tape , so I really did need my brother 's help . We went to AutoZone ( after attempting to go to the Arlington Napa , which was CLOSED when they were supposed to be OPEN ) and bought a new alternator , then spent the next several hours trying to get the old one out .
