I picked my truck up today after it it was repaired after hitting a deer in Aug.
I told the shop it had the heavy duty cooling package.

They sourced and installed a used standard duty cooling fan.

I need to check the alternator to see if it is the high output or standard output.
How do I tell the alternators apart? There is no convenient tag like on the cooling fan.

Disregard, I found the part numbers on the Quadratec site:


180 A Mopar Part #: 56029597AB

220 A Mopar Part #: 56029765AA

240 A Mopar Part #: 56029803AA

I got the old parts, the truck had the 220Amp alt. originally, now I need to find the part number on the used one they installed.

Mine has the 240amp alternator . It also has the AC plug in in the cab . I am think that went hand in hand . I could be wrong though. Mine is a Rubicon.

My original alternator was a 220A made in Mexico, the shop installed a used 240A made in Japan. I'll consider that an upgrade.
