Can't unclip rear ignition coils (2016 Odyssey) Sign In

Hello!

I completed a spark plug change on the front half of the engine.

I cannot seem to get the rear ignition coil wiring harness to separate. I've tried hands/fingers and a small tool to depress the tab while trying to wiggle it out with pliers. Getting any more aggressive feels dangerous to the plastics and wiring. Any tips?

Sometimes it helps to push it in first to take the pressure off the clip.

Also sometimes you can help it by lifting the other end of the clip with a pocket screwdriver.

Don't force it off. That will only break the clip. It has to be lifted off the detent.

Here's a quick video clip of me trying to do this. I couldn't really get my hands on it well to wiggle with the camera there, but am I in the right ballpark?

You might be able to come in through the front through that slot with the tiny screwdriver and lift up that end of the tab.

Thoughts/ideas. Dang plastics go brittle it's hot in there.

IDK made a collection of #1 cheaper, flathead screwdrivers, plain propane torch while tip glowing make a right angle as a hook push or pull with it.

Other is see the foliage in the pic? Is there a good reason that it's able to get there? Just asking,

Tom

The foliage fell from the tree it was parked under while I was in and out of the house grabbing tools with the hood propped open

I'm not sure about getting into metallurgy but I do have a couple of picks laying around that I might try, so thanks for that idea.

I guess a good basic question is should I be pressing down or pulling up, and on the side closer to the grill or the front seats?

Just a point on + about clips: Fords, real Fords made PU*SH clips if wiped off the PU on one side SH on the other side of the bail. Broken (done wrong, brittle too) a wire tie worked with those broken.

Never seen on other makes still broke many deal with lots of ancient cars lots older than this + use them!

Search till your blind for pigtail ends doubt they are out there. A few wire ties on my own fleet still makes me sick I had to,

Add to that on "make UR own tools."

Yes, the odd dental like stuff or other. Available new, price usually Snap-On not worth it to you.

Torch is relative cheap to work you need a bench vice with an area that's an acting anvil. While a metal is glowing hot it's malleable but know glowing hardened metals lose that property.


Refresh here. A workbench mounted vice is a must. Torches? Propane or hotter acetylene.

Cost of tools and place is a killer for most,

Tom

If you're pushing down on the clip tab, reach in from the front with a pick and lift the front half.
