Chevrolet GMC Cadillac Hummer 17 Piece Performance Ignition Kit TRQ Performance TKA06291

All right. We want to disconnect the battery. Disconnect the negative cable, use an 8-millimeter ratchet wrench or a wrench, and slide that out of the way. All right. Now, replace the plug wire. Just grab the top of the wire, pull it down. And then, at the spark plug, you can try twisting this first. See if you can loosen it up. Try to pull it. Try not to bend the aluminum too much, but if you're struggling to get it off, you might have to a little bit. There you go. Pulled that one out.

You can take a little dielectric grease or some silicone lubricant. Just put this in the end right here. Then, you want to take the heat shield off the old wire and reuse this. Now, we can line this up, up top on the coil. And then line it up with the plug. Slide it in position. Make sure it clicks in place, just like that. Then you're going to do the same procedure for the other wires.

Now, we can hook up the battery. Line it up, get it started, and snug it up. Just make sure it's not loose. That's good.

Okay, friends. Before we get started on doing our ignition coil here, we just wanna make sure that you have safety is your number one concern. Always have your eye protection and your hand protection. Let's get started.

Let's come right over here on the passenger side of the engine. If we're looking for the coils, you're gonna see them right up along the top or side, right along here. All four going down the side and then, of course, on the other side of the engine you'll have the same four. Now, we're gonna show you on this front one right here, because it's the hardest one. And it's not very hard at all, but it is the hardest. We need to grab these heater core hoses, move them out of the way. Once they're out of the way we need to remove this bracket. Use your 10-millimeter and take off this nut.

The next thing we're gonna do is take a nice small pocket screwdriver, you can use pretty much anything, including your finger, but if you take the small pocket screwdriver, you can go right along here, lift up on this tab, and then you should be able to draw your electrical pigtail away.

Now let's move on down from the coil to the spark plug wire. Grab onto it. Give it a nice twist and pull it right off. Looking at the coil on either side, you're going to see a 7-millimeter bolt, remove both. Hold onto that coil, there's nothing holding it on there, except for this bolt at this point. There it is, friends.

Now it's gonna be time to install our brand new coil. Just gonna take it and bring it right down here, and I'm gonna line it up with exactly where I removed it from. Start in both of my bolts before I tighten either of them down. Go, both are straightened. Let's go ahead and snug them up. I always like to use a regular ratchet to make sure they're snug. Go ahead and connect in your electrical connector. Let's grab that spark plug wire. Go ahead and use a little bit of dielectric grease in there, that's gonna be helpful, and then connect it right onto your coil. Listen for a little click noise, give it a nice twist and a nice little tug, to make sure it's secured on there. You also wanna make sure that your spark plug wire is in no way touching that exhaust manifold.

So, now the replacement process for all the rest of the coils would be the same at this point. But moving along to finish up with this coil, we need to make sure we get this bracket back on. I'm gonna take the bracket, put it on there just like this. Snug it right up. There we are. Make sure it's nice and tight. Make sure you secure your heater core hoses. Double-check everything. This looks great.
