Years ago i used red loctite on my buddy's spare tire wing nut. He was a cop that rode in an area with a lot of construction. He didn't see the humor in it when he had a flat in the rain and couldn't
In my search for a better alternator i came across a post by ilya5903 on Cumminsforum.com about using a 2001-03 5.9 Durango 160 amp alternator. Today i hit Pull-a-Part and lucked out. They had 2 Durangos and one was a clean 02 5.9 with the factory alternator. $22 + $7 core. Had it tested on the way home and it works. Swapped the pulley and 15 minutes later its on. Definitely puts out more at idle than the stock 136 amp as i can now have all 3 air compressors, a/c, high blower, headlights and stereo on with truck at 800rpm in drive and had 13.9 volts. 14.2 at idle in drive with everything off.
Factory pn 56029915AA.
