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 engine ignition coil on this 2006 Chevy Impala, pretty much the same for any 2006 to '12 Impala with the 3.5 liter V6. The only tool you'll need is a 10mm wrench or socket and ratchet.
Start out by removing your oil fill tube and pop the engine cover off, put it to the side, and put that tube back in so that nothing gets into the engine.
Your coil is located at the back of the engine. There's a coil assembly there and you'll want to disconnect the lead by pressing down on the tab that's on top and pulling it off. Now, you'll want to disconnect all of the wires to the coil. We will, later in this video, show you a diagram that shows you the proper way to reconnect these. There are four 10mm bolts. You see one there, one that's down in the back .you can barely see it a little bit there . another one there, and another one in behind that. Those are 10mm and we'll just fast forward as we remove those. You can see as we remove that last bolt the whole coil pack comes up and out.
Now, install the new coil. Make sure that you have the harness connection facing toward the driver's side of the vehicle. Put it down in, and start your bolts on. I'm going to fast forward here. We always recommend you start the bolts first by hand to make sure you don't cross thread anything, and then tighten them up. These bolts should be probably tightened to about 8 to 10 foot pounds or 80 to 90 inch pounds.
Here's a very important diagram. You need to make sure you put the plug wires back on the right place on the ignition coil. As you can see if you're looking at the engine from the front of the vehicle, the front side of the engine is plugs number 2, 4, and 6. The back side is 1, 3, and 5. Then, you can see the ignition coil on the back, the first one you plug in is 1 . that's the first one on the left . then 4, then 2, then 5, then 3, then 6. You can see, here, Don is plugging those wires back in. Every once in a while you'll see him looking over his left shoulder there. He's got a little handwritten diagram next to him, the same as that one we just showed you just to show him how to put those plug wires on correctly.
Reconnect the electrical connection on the driver's side and then remove your oil fill tube and put the cover back on. It's just got a couple of rubber plugs that go over studs. Push it down on and put the tube back in and you're all set.
