4.7L ALTERNATOR UPGRADE (Jeep/Dodge/Chrysler)

160 Amp Alternator for Chrysler/Jeep/Dodge 4.7L:

Jeep 4.0 Alternator Upgrade:

In this video we take a look at the stock 117 amd and 136 amp alternators that more Chrysler/Jeep/Dodge vehicles came with. I have found a direct bolt-up swap to upgrade those alternators to 160 amps!

This swap is great for anyone running a winch, snow plow, offroad lights, upgraded sound system, so anything else which requires additional electrical capacity over stock

The vehicle in the video is a 2001 Jeep Grand Cherokee 4.7L, but this will be the same for any Chrysler/Jeep/Dodge with the 4.7L and 4.7L HO engines.

Yes, Denso is the OEM for Chrysler. I work in the factory where both of those alternators were made. The new one you have is simply the next generation and better.

I have been doing the "love tap" for weeks now. I have been order an new alternator for my grand jeep cherokee limited, 4, 7L V8 from 2003. My voltage goes up and down all the time when i drive. Thank you for this video, now i know how to change the alternator!

The 117amp unit is for the jeeps that don't have rear window defrosters. Any Jeep that has a rear window defroster comes with a 138amp magical mystery box.

I've done this swap on the side of the road, took me about 10 minutes. Went through two of these stupid OEM alts before going with the upgrade. Just got another nice 2004 GC with the 4.7 and will do this swap soon.

I like the beater method on all my vehicles except my Chrysler 300 so I'm subbing to your channel.

I have a 07 with a 4.7 did the same upgrade. Defiantly an upgrade.

Your “love tap” trick saved me a $200 tow charge

I was just searching today for a Durango alternator upgrade for my 4.0 WJ.

My alternator on my 03 dakota slt was giving me the same symptoms. With my boat trailer lights it would struggle, so i went on the A shop and bought a 160amp alternator for less than $100 and no core. So far so good.

My old mustang and GM blazers had like 40 amp alternators. I upgraded to 140's and that is a lot.

[MUCKFOOT]

ive been jamming Pantera a lot, my alternator is smoking

[danhambrick]

Nice upgrade Douglas 👌 Martin built did an alternator shoot out video on his channel.I believe this one beat out a 250amp one...💪💪

BTW, There are 3 ways that light up the red bulb that says "BRAKE" on the WJs dash. #1-Parking brake is on. #2-fluid is low in master cylinder. #3-There is a current fault with the ABS system that's been there long enough for the ABS warning light to have burnt out.

I need a video to do head gaskets on my 2005 4.7

[sixpacksandsrts]

Nice. Would if been nice to see an amp clamp over the positive cable to show actual amperage comparison. Score... keep up the vids

[raulbueno]

Hey what's up man I have a 2001 Dodge Durango with a 4.7 Powertech motor fully loaded and I use that truck to tow a lot of weight and I still have the original alternator 160 amp alternator ad with a 810 battery

[Fab-ecos]

You plow with that? Thought you can't plow with. Unibody jeep. I have 2001 Jeep grand Cherokee with a 4.7 liter. Would love to plow with it. How did you or where did you get the plow?

[outdoorsmansgarage]

Im looking for a bigger alternator for my GMC 3500

Rock auto under 02 Durango shows the Denso 2101139 as fitting these also. Whats even weirder the one you listed links to Quality-Built 13913 Premium Alternator - Remanufactured.... says does not fit 02 Durango but amazon has been wrong in the past.
