Hi, I'm Mike 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 ignition coil. On these vehicles, they recommend you replace these coils at 100,000 miles. Also, sometimes if your engine runs a little rough and turns the "check engine" light on and you get a code that says, "Cylinder 1 or Cylinder 3 or something misfiring," that's usually a coil going bad. It is a pretty easy replacement. You'll need a ratchet extension with 8mm and 10mm sockets. If you don't have an 8mm socket, a flat blade screwdriver can help you get the clamps off as you'll see.
Working from the passenger side, you want to remove two bolts that hold the top of the air box: one here and one right here. Now to remove this, you want to remove this intake tube which is a clamp here and a clamp here. Remove that tube and then loosen both this one and this one to pull this apart. I'll speed this up a little bit. You can either use a flat blade screwdriver or an 8mm socket with a ratchet and extension to undo those clamps. This also has a small vacuum line on here. Twist and pull that off, and then this goes up, and there's also a line right back here. Just pull off of there.
This big vehicle has been sitting for a while, so I'm just using a vacuum cleaner to clean up the vacated mouse house that's sitting on the intake. Okay, then take, twist, and get this collar off here. You can see here are our five coils. Pick any one of them, and just remove the 10mm bolt. Each of them have a little gray clip that you just pull on. Use a screwdriver. There's a little tab right in the center. Push the tab down and pull the clip right off.
Then there's just a tab for your thumb. Press that. Remove the lead, remove this 10mm bolt, and then, once you have the bolt removed, just move it around, shake it up and down a little bit, and then the coil comes up and out.
The new coil from 1A Auto is exactly the same as the old one. Put it right down in. You want to just push it straight in. Tighten up the 10mm bolt. Plug your lead back in, and then put the locking tab back in place. Repeat that for any cylinders you need. The cylinder order on these is usually just from front to back: 1, 2, 3, 4 and 5. If you get a code like "number 3 cylinder misfiring," that's usually a bad coil, so you'd replace the number 3 coil.
To put it back together, put this on there. There's a little notch that should stick up right there. I've got my two bolts already kind of in there. Right here is that hose. Push that hose down first. Put this down in place. I'm just kind of maneuvering it into this hose here. Push it into place and twist this hose a little bit off. Push it down onto here. Get it good and tight on there. Hook up the vacuum hose. Use an 8mm socket to tighten up. Just inspect where the hoses go and their housings. Make sure they're nice and tight, and then tighten up our clamps. Again, you can use either a flat blade screwdriver or an 8mm socket. Then we go back to our 10mm socket and then tighten them up and you're all set.

Solved multiple misfires 04 Colorado

Product quality is same as factory at a fraction of price. I have been dealing with multiple random misfires and nobody could figure out why. My mechanic said I had clogged injectors and did an $100 induction service to no avail. He also said he tested the coils and they were fine. The misfires were more often in cold weather. So I went out on a limb and ordered this set. No more misfires!!!
Great service and quality

I purchased the set of 5 for a great price. A little worried about the cheap price but we will see after time if they are good for the long run. Very easy to install. 4 hose clamp screws. 2 bolts and 1 vacuum hose to get to them. 1 electric plug and 1 screw to remove the coil. They look very nice and not cheap.seem to be working fine. Truck runs great. 2006 Chevy Colorado crew cab.

I priced these coils at my local auto supply and it was much higher than 1a so I was sceptical about the quality, but I have since installed them and have had no issues. It's only been a few months but to this point I am very satisfied. I would recommend.
Great service

I received the parts in the time it said, along with once I received them they were packed great. I no longer needed the parts because I sold my vehicle a day before they arrived, so I called to return them. 1A Auto has great customer service they explained everything nicely and treated me with respect definitely referring to friends and family!
BEWARE THE BOLTS!

I have only recently installed these coils on my 2006 Chevrolet Colorado. I will update my review as time goes on to see how they perform.
HOWEVER! The bolts on these coils are not as strong as the OEM DELPHI bolts that come on the stock coils. When I was installing my third coil, I felt that I was not tightening the bolt too hard when it snapped. Half of the threaded portion remained in my engine block, and there was no way for me to fasten down the coil.
Fortunately I managed to drill/ use a screw removal bit in a hand drill to eventually remove the broken bolt. I STRONGLY RECOMMEND if you use these coils, that you replace the bolts with the OEM ones from your original coils. The bolts can easily be removed/ installed into the coils with a punch and hammer.

The coils themselves are great and work. But like another review said becareful of the bolts use the ones that came with the stock coils you'll have hit them out with a punch. The bolts where fine for 4 out of 5 coils just don't force them.
