2002-06 Nissan Altima Sentra 4 Piece Ignition Coil Set TRQ ICA61485

Use a 5mm Allen key to remove the plastic engine cover. There are one, two, three, four bolts holding it on. Lift that off and put it aside.

These are your four ignition coils. I'm going to show you how to remove this one, procedure will be exactly the same for the other three. Start by pushing this clip in and wiggle the connector out. Use a 10mm socket and ratchet and use a retaining bolt. Put that bolt aside. Grab it on both sides, and kind of wiggle it, because there is a boot that goes down over the spark plug. It's got a little suction to it. Pull it out and that's how you remove the coil.

Here's our old coil from our vehicle, and our new coil from 1aauto.com. See, they're an exact match. Got the bolt holes on either side, same style connectors, and the same style connector at the spark plug end. This will fit perfectly, and get the car running great again.

Install our new coil packs. Now this bolt hole here is just a metal insert into this plastic valve cover, so we're not going to over-tighten those, just going to tighten them very carefully. So slide the coil down. Push it over the spark plug. It will sit in there. Get the bolt started. I'm just using my wrist to tighten it, and right when I feel it get tight, I'm going to stop, 'cause I don't want to pull this threaded insert out of the plastic valve cover.

Reinstall the connector, and repeat this procedure for the rest of the coils. Reinstall the engine cover, and reinstall your four bolts. These bolts are just going into aluminum, just holding on the plastic cover. Not a lot of torque on these. The job is complete.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the ignition coil on this 2003 Nissan Altima with the 2.5L four-cylinder engine. It's the same process on the Altimas and Sentras with this engine from 2002 to 2006. You'll need a new ignition coil from 1AAuto.com, a 10mm socket, a ratchet, and a 5mm Allen bit.

To access the ignition coils, you first have to remove this engine cover. It's held in by these four 5mm Allen bolts. We'll just fast-forward as Don removes these. He's using a ratchet with a 5mm Allen bit. You could also just use a 5mm Allen wrench, as well.

Now, the cover just lifts right off. Here are your four ignition coils. It's held in with one 10mm bolt in the harness right here. Just push the tab and pull that harness off. Then remove that 10mm bolt. Now the ignition coil just lifts right up and out.

The old ignition coil is on the left; the new one from 1A Auto is on the right. You can see they're identical, and will fit exactly the same. Take the new ignition coil and just push it down into place. Then replace that 10mm bolt and reconnect your harness. Repeat this process for however many coils you want to replace. Now, all that's left is replacing that engine cover and those four 5mm Allen bolts.
