Sparks plugs and ignition coils -anyone ever changed them?

[XB70]

I was thinking of doing this on the Caddy.

The main dealer has replaced one but, being conscious of costs and given that there is probably a wealth of experience on here, is this something that can be done at home by a complete novice (me!)

Thanks in advance!

it's normally pretty easy (unless it is a jag XJS V12 then its of with the intake manifold and AC systems) and once once one goes the rest tend to follow.

Agree - It's easy enough with the right sparkplug socket and taking your time and doing one by one (not unplugging all and doing it in one go!). Of course not mixing up the coil cables or cross-threading the new spark plugs helps as well

Thanks for the replies!

While I am busy, with the family away, doing odd things around the house (yay for tutorial videos on YouTube), I think this may be beyond me given that:

a) I don't possess said tools (I looked on YouTube and they appear to use a long socket thingy to get the sparkplugs); and
b) I am guaranteed to *&^ it up

Is there any handy spanner people here around the area (I am in The Villa now) who have the kit and be willing to give me a hand on doing this? I can order all seven coils and spark plugs for less than I was charged for one by Cadillac but, since I am selling the car, I need to keep the costs down rather than spend thousands at the dealers.

Beer tokens, a full English and the usual forum offerings if anyone can help!

Cheers

Rich lives in the villa and his youngest daughter's probably picked up enough by now to be able to be able to do plugs and coil packs!

It's an easy job. If you don't mind a short drive to DIP you can use my tools and nose the car into the workshop.

Just check the socket size on the plugs. Not sure whether the yanks do anything different. I have a standard sized spark plug socket.

Thanks so much! I am sure that many on here are going "WTF? Spark plugs? Is he serious? I have changed diffs using a bent ruler, a rock an some matchsticks" but the last ones I changed were about 20 years ago on what was then a 1978 Chrysler Sigma which you could run around in the engine bay! OMG....I feel old!

I think they should be standard size spark plugs (they are AC Delco ones) so I will order the parts and let you know when they arrive. so we can sort out a day. Reform Bar & Grill is not that far away so we can either fuel up in advance or afterwards in celebration!

At the very least, it's a good chance to say meet in person!

Hi. Just ordered the parts from the US and they should be here by this time next week. I will drop you a PM so we can arrange a time to install them. Thanks again!

No worries. I'll be in the garage most nights anyway for the next few weeks.

A huge thanks to Phil (Shirt) for helping me in this. Suffice to say that I demonstrated that, if I had tried it myself, it would have made for a very interesting post on here!

The fuel rail and injectors are not the ignition coils as I now know!
