Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace an ignition coil on this 2006 Jeep Liberty with the 3.7L V-6 engine. The only items you'll need for this are a new ignition coil from 1AAuto.com and a 10mm socket and ratchet with an extension.
Right here, is ignition coil 1, 3, and 5. On the other side, is ignition coil 6, 4, and 2. We're going to show you how to replace ignition coil 1, but it's a similar procedure. You just pull that hose out of the bracket, disconnect the harness by pushing the tab and then remove that hose clamp. This just pulls right off of the stud. Then, you want to remove this 10mm nut. We'll fast forward as Don does this. Once that's removed the ignition coil pulls right up and out.
On the left, is the old ignition coil. On the right, is a new one from 1A Auto. You can see they're identical. They're going to mount exactly the same. Take your new ignition coil and push it down into place. Now replace that 10mm nut and tighten it up. We'll fast forward as Don does this. Reconnect your harness. Push that hose clamp back into place. Re-clip the hose into place. Then you're all set.
We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

I ordered these to replace the ones on my 2006 Dodge Ram SLT. Truck has about 150k miles on it. Product was very nicely boxed and packages. Each coil was bubble wrapped. I put silicon grease on the boots that slide over the spark plugs with a q-tip. Everything went together perfectly and was a simple job. I have about 400 miles on them with no issues.
Excellent service

My Jeep Grand Cherokee was misfiring badly on multiple cylinders so I ordered this coil pack on a Friday and it got here on Monday. Slapped it the car and shes running like a top again.
Great replacement parts!

The parts were a perfect match when I put hem in my engine compartment. I no longer have any misfires and my truck runs very smooth because of it. I would recommend this part and any other parts from 1A Auto to anybody I know. Excellent price and fantastic quality on everything I have bought from this website.

The platinum spark plugs really go a long way when it comes to performance and a great deal for a V8 coil set.
Perfection!

I ordered these on a whim when I couldn't figure out why my Ram 1500 would stall without a check engine light. They fit perfectly. Looked almost identical to the Original parts, and seem to have fixed the problem. If that wasn't enough... They came in exactly the amount of time A1 Auto said they would! You guys rock!!

Defected and caused 0304 and 0308 codes on my 2002 jeep v8 , would turnover but would take 2min to start up then run rough till it got to an idle. Replaced with OEM and no problems now. Wasted $115. And should of known better but at the time couldnt afford OEM.
It's what was needed

Works great in my 2002 dodge ram 1500 4.7 v8. Replaced original coils with 250,000 miles on them and these new 1a auto coils made the trucks ignition system function like new. Thanks 1a auto!
No good, 1/4 coils faulty as of now

Installed new coils and spark plugs, instantly got a check engine light for P0301 (misfire in 1st cylinder). Replaced the new coil with an old one and light went away. The next day, I get a P0356 (malfunction in 6th cylinder), replaced that NEW coil for an OLD coil and the light went away. Avoid these coils if you can.

Garbage, I replaced all 8 coils on my truck. Slowly but surely each 1 has gone bad. Less than 6months after replacing them. Don't waste your time or money.

Didn't even last a year
bottom line, if you need to get them for bottom dollar now and plan to spend the money to put in OEM later then these will cover your needs.

had 1 of 8 fail after about a year causing misfires. not sure if some of the other issues ive been having with hesitation can be linked but it started around the time i installed these and the 1A auto spark plugs. I am not a mechanic, just tired of paying them.
Easy to replace

Is this hard to do by a non mechanic?October 25, 2017

No, not at all I did this in under 2 1/2 hours and had no clue what I was doing at all, It is just like changing the spark plug wires in the old school engines.
Hope this helps

As long as you have the necessary tools and may identify the location you will not have a difficult time at all. We certainly recommend taking your time as well as referencing our video for a general instruction.

I would say it depends on the application. I did this on a 2008 Jeep Grand Cherokee and I would rate it probably 2 or 3 difficulty on a scale of ten. Really once you get under everything (intake box) its simple, there is one bolt per coil and one plug wire per coil so if you do it one at a time theres no way to mess it up just dont over tighten. I put some of the dielectric grease on inside the boot so the plugs wouldnt stick to it and to protect from breakdown from the voltage over time. If youre doing this on a similar model I would recommend this over taking it to a shop any day. Its not nearly as difficult as it may appear.

We have a few different aftermarket companies build these parts specifically for us who are based in either China or Taiwan, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please don't hesitate to ask.

It's been a while and unfortunately I don't have the packaging or know the manufacturer. I can say that they worked just fine and continue working today..
