Just to confirm this will work with a 4.0? I've only seen the 2.5l referenced.

Ah... I had never seen it referenced working on the 2.5L. Yes, it does work on the 4.0L.

is this confirmed to work on a 2.5l?
I've got to get it outta the parking lot it is stuck in tomorrow - and an upgrade instead of a stock replacement is always ok by me

Just stopped my my local oriley's and picked up one of these alternators. Installation supper easy, but I noticed that my belt is now very tight (larger alternator?) The little tentioning wheel is almost all the way pressed back just under normal use. My idle speed also rose about 200rpm after the upgrade. Is that normal? Or is the belt to tight? Should I get a larger belt to accommodate the new alternator?

I would also like to know if it is reccomended to upgrade the stock 8awg wire to something more like 4awg, or even 2awg.

Thank you!

I installed a 136 amp unit I picked up from advanced auto for a 98 dakota on my 98 4.0 about 2 weeks ago. The stocker finally crapped out on me. Fit just like the stock one... and now my dome light doesn't flicker when my seat heaters are on. Guess she needed the extra juice. I was too lazy to swap the pully, the belt just rides towards the back of the pulley with no problem. Didn't notice an rpm change or belt tensioner problems kjmccar - not sure if we have the same tensioning mechanism though. The wiring only needs to change if you are using accessories that require the full output of the alternator... it doesn;t put out 136 amps all the time, it puts out the load that is called for.

The stock alternator is on the left and the durangolt's is on the left, despite the size difference it is a direct bolt in replacement.


Safety 1st, safety 2nd, I disconnected the +ve lead from the battery and secured it out the way with the battery tie down, now my only danger was the scorching sun.
I had replaced the stock battery 2 days ago for a Bond platinum 34/78 (1090 CCA! for under $100), which is why it is the only clean thing under the hood.


With the power disconnected I removed the alternators 2 wire plug and the power cable that leads from the alternator to the +ve battery terminal


Time to take the fan belt off, I'm glad I put a flexilite fan in, now I have room to work!


The tensioner has a 1/2" socket so it is a peice of cake to release the tension with a socket wrench and slip the belt off the idler.


Undoing the two bolts (15mm) that held the stock alternator was the hardest part of the job (they were on good), it took 20 minutes of cursing and soaking in PB blaster be they relented.

A further 10 minutes of cursing ensued as I tried to get the new alternator to fit on to the mounting bracket, it would almost go but I could not get the bolt through....


Then I noticed this, the bottom mount has a sort of nut-sert thing on it that held the bolts thread and it was stick out on the inside too far!, 30 seconds later I had tapped it out all of 1/16" and bingo! everything lined up!

I tightened everything down good an solid reattached the cables to the new alternator and the battery, re-fed the fan belt, then with crossed fingers jumped into the cab and started her up.
It's always a good feeling when not only does the engine start but it runs and there are no loud bangs or screeches. :-)

I've done a couple of tests with the 1500W inverter running an 800W drill and I can run it alot longer and harder before the voltage drop alarm goes off!

Comming soon(ish) Dual battery install write up and a winch install!
This is good... Read a lot about guys doing it on the older TJ's... but seeing as you did it on an 05, I know it will work on my 06!

Does this mean that Since I have a 2003 TJ, I will have to upgrade to the 136a? What is my stock alternator rated at? Need to do this swap and its a real headache to read and understand all of the what ifs.

stock is 117 amp peak, 19 amps isn't worth upgrading unless you NEED a replacement or you're getting low voltage alarms.

My only other question, is does the advanced auto alternator fit a 2003?

Wanted to give an update on my specific jeep. 2003 wrangler. The 160 amp fit like a glove and can be had from autozone for cheaper then advanced auto after the core. And my local store had one laying around. Wanted to update because I, like many others, try to find a specific example of a certain year model. Well here it is. It works just fine. Thanks everyone
