Today we are removing the alternator on this 3.6 engine. In the video I remove the lower bracket up its optional. I mainly wanted to show how the bracket mounts to the alternator and was limited on room to film while on the vehicle.

Great video! Quick question – do you know if a 2016 JK Wrangler has a smart alternator? Or is it standard? I’m looking at a dual battery set up with a dc dc charger.

Bill says:

Great video and it’s great to know all the size tools required in advance. I will be doing an alternator upgrade to my 2017 JK in the near future.

Thank you ! clear instructions

Yeah my belt tensioner is not budging not even a little bit I feel like if I pull harder I’m going to break my 1/2 off inside it

Fernando J. Sulsona Anziani says:

Is it really necessary to remove the triangular bracket? I think you can just remove the two long screws holding the alternator to the engine and the two short screws holding the alternator to the triangular bracket. Thus leaving said bracket in place.

Steven Acuff says:

Thank you for this clear and simple how-to. I am not skilled in auto-mechanics, but, with this video, I feel confident I won't screw up my Jeep.

Excellent video! I'm actually replacing a water pump on the same vehicle and it looks like I need to pull this off in order to do that.

Alex Moreno says:

You are a GREAT MECHANIC, sadly WRANGLERS suck! I believe my ALTERNATOR just went on my 2014 Unlimited Sahara with only 45 Thousand Miles, Started the jeep up went and got coffee came back out put key in ignition and NOTHING! No lights, No power, wont crank….We even got a new fully charged battery try jumping it and NOTHING! With new battery plugged in everything turned on, but NO cranking. Cant wait to get ride of this 2014 Wrangler Unlimited….FIRST AND last Wrangler, was thinking of trading it in for the new Jeep Pick up…..Nope…..Going Tacoma now!

I have a 2012 JKU 3.6L looking to add an upgraded alternator. What size alt do you recommend for a 1800 rms car audio amplifier?

Austin Smith says:

I noticed there wasn't a ground for the alternator like on others I've changed. Does the alternator in the Jeep 3.6 ground through the bolts into the engine block?

Regan Strand says:

Best online mech video ever. Direct… to the point and simply put. Angles were great. He even said the right size sockets needed. I have never changed mine before. Did a full replacement in 45min.

Awesome video

Steve Belcher says:
