Removing ignition coil

[Harold]

Hi chaps,

Planning on changing my coilpack this weekend, but last time I had a look at it the screw heads were pretty damn rusty and seemed to crumble when any twisting force was applied.

What are my best and easiest options for removing these pesky buggers? I've never had to remove a rusty screw before so am unsure of the best method.

And I don't really want to tackle the job until I have everything I need and know what to do, as it's not in the most easily accessible place.

Thanks all.

Bolts will be rusted in the coil.

We always replace the bracket with a new one when replacing the coil.

So no need for drilling out any screws? I can just take the old coil & bracket and chuck it in the bin?

I did this last weekend just simply by drilling out the screw heads and using a small punch.

takes 5 mins - job done!

I've done this recently as well.

Drill out the tops of the bolts, then remove the coil and the heat the remainder with a blow torch and they will come out easy enough with a pair of pliers.

Make sure you replace them with something stainless with an allen head.

What's the part code of the bracket. I took mine off to replace but couldn't get the screw out, only have a drill but no vice so might be tricky.

What kind of material drill bit should I be using? And should it be the same/a close diameter to that of the screw itself? And what length & pitch bolts should I be looking for to replace them? Would definitely be much happier if they were S/S with a hex head

Apologies for my noob questions.

I found this pic from the archives -


Looks like I'll be ordering one myself.

Excellent, will have to order one

Considering that my drill has just died and I can't afford a new one right now, if I just order the above bracket can I avoid any horrible rusty screws and just chuck out the old coil and bracket as a whole?

Have you already managed to get the igniter off ok?

Mine was a royal PITA as the screws and igniter had managed to corrode together, due to two different metals.

Didn't even get a chance to attempt it this weekend, so I can expect a whole load more rusty screws attaching the igniter to the coil?

Mines was corroded together, i think ill get a new bracket and maybe spend a few hours on it when engine is out

Hmm, may leave this job for a little while if it's going to involve hours of drilling out rusty screws. With no garage access i'd rather wait until i have a nice sunny day, a working drill, all tools necessary for removing horrible rusty xxxxxx screws and a lot of patience, and maybe a lump hammer for when i want to smash the crap out of it.

I think my current coil is ok at the mo, it's just preventative maintenance.

Thanks for the advice chaps.

If the screws were properly corroded to the igniter did you have to drill out and re-tap?

If this kind of thing is involved then i'll be visiting my local garage.

If your replacing the bracket why drill them out ? When I replaced mine I removed the bracket then smashed the crap out of the coil until I could see the heads of the screws and then knocked them off( which was easy due to how much corrosion they had). I didn't replace my bracket I just soaked it in coke and used scotchbrite. It never occurred to me to replace the bracket.

When referring to drilling out screws, I was talking about those attaching the igniter to the bracket. Are these the ones you're talking about removing?

My mistake my ignitor came off easily and my coil pack was rusted up.

There isn't actually any thread in the igniter, they just pass through and bolt to the bracket. Drilling the heads of was not enough I had to drill them all the way through. I actually had enough meat left on my bracket that I could clean\retap the threads, but if they are cheap enough I'd definitely suggest you save the hassle and get a new one.

Bracket ordered, hoping for a dry weekend and that the igniter screws come out easily!
