Replacing spark plugs

wallie
My friend has this 03 or 04, Cadillac Deville w/the big North star engine with 97,000 miles on it and she asked me to help her put spark plugs in it.
She went and got spark plugs for 20.00[:0] apiece and she said there are no spark plug wires[?] something about direct ignition. She even went so far as to buy this Haynes Repair Manual just in case we get stuck for info. But the manual does not really show or give a lot of info for this particular model.
I was wondering if anyone ever had experince in this. It looks like the plugs are on top behind a cover and for a transversely mounted engine the back 4 plugs looks easy to get at.

    The covers that are on top of the plugs hold the plug connectors.
    Like plugging in a circuit board.

    The new engines today. You are better off taking them to the dealer and have such work done. For if something is not right you stand a chance of messing up a lot of electronics on the engine.

    Yes it may cost a good penny to have a dealer do the work. But they know how to do it correctly.

    The secondary electric systems on todays cars and truck carry enough voltage and amps to kill a person.

    A North Star engine is simple compared to the 8 plug four cylinder Mazda engine used in Ford Ranger pick-up trucks. Some of them you have to remove the intake just to get at the plugs next to the firewall.

    My wife has a Ranger, i just put plugs in it too.It CAN be done without removing the manifold but you need a 1/4 in. ratchet set and a whole array of extensions and univ. sockets...It was HELL..[}:)]

    If it ain't broke don't fix it. Save your money for when the starter goes out and the intake manifold has to be pulled to get to it. We are talking 3 to 4 hours labor time. [B)] Plus a starter[B)] plus tax[B)][B)][B)] But I must say if you take care of it it shall last a while. I have a few cars and one is a 95' Cadillac STS with the northstar. It has 344,244. Had to go look[:D] It eats a qrt of 15w-40 a week and will leave carbon all over the tailgater behind me in traffic but its a clean car. Can't complain. Had it for about 5 years know.
