Spark plug replacement for the Alpha.

[H3ALPHA]

I am approaching that point that the plugs need to be replaced.

I can find videos, step by steps for the I5 engine, but none for the Alpha.

Anyone know where I can find this, so I can see if I can do this myself?

Thanks.

I just had my wires and plugs replaced Some are really a pain to reach. I had my co worker do it. It took him about an hour with several cuss words. It is just like any other GM 5.3l v8. With less space to work with.

Make sure you let it cool off before messing with it.

The plugs I got came pre gapped. They were AC Delco. Supposed to be OEM but they did have a different part number than the ones we took off.

If I recall correctly, it's helpful to have a set of various extensions and wobble/flex pieces to help you reach some of those plugs.

My understanding is the original ones installed have been discontinued and the new ones are Iridium which are better and correct for this engine.

Been reading everywhere I can that the reach is tough even for guys who are 6' 6" with long arms.

I am not even 6' and haven't changed a spark plug since I sold my 1967 Shelby GT500...

Trying to see what work I can do to keep costs down.

Right now I need to:

- replace the rear differential mount
- oil pan gasket
- tune up

Figured if I could save $600 doing it myself, why not.

Do you guys know of anywhere that might have a video on this?

The rearmost one on each side is a pain but can be done thru the fender well with an extension, the other 6 are no big deal.

Mostly agree, but DS front plug also tight - I pulled out battery and a bracket for room.

Back two very unpleasant; but with collection of extensions and knuckles can remove all.

I did need to stand on something to reach them.

I cursed and cut my knuckles a lot.

But I got it done in a couple of hours.

Air ratchet's are your friend. Just have to break the threads loose then zip off the bolt/sparkplug/nut/whatever. Makes life soooooo much better when working on modern vehicles.

Are the plugs the same part # for v8 as i5???
If so I've got 6 of them with Lil to nill mileage on them that you can have for the price of s&h.
There like $7 minimum a piece. I kept the 5 I removed from my H3 which had like 12k miles on em lol!
The other one is brand new never used. Let me know. You'll have to buy just two new ones.
