Tuneup a Lumina

Hi Everyone,

            I’m would like some information on changing the spark plugs
on my 1992 Chevy Lumina. It has the kind of 6-cylinder engine where
three cylinders are in the back next to the firewall and 3 are up
front. The book says I have to disconnect and unplug everything, take
out the window washer reservoir and take out the mounting bolts from
the front of the engine and rock the engine forward. I would like some
feedback and hints about doing this. Do they do that at the shop?
 sounds like alot of work. Thanks for all the help and
suggestions.

Roscoe

    It is not as intimidating as it seems.
    The front three are pretty easy.

    Be sure you know where the ignition cable go as you take them off.  You
    may well damage them anyway.  Sometimes they are stuck on so tight that
    it is hard not to destroy them..

    Those engines have an upper engine restraint system that is normally easy to
    get to.

    When you remove one of the bolts, the entire engine can rock forward to give
    you access to the rear plugs.  The restraints I remember often have a second
    hole where you can install the bolt to hold the engine in the forward
    position,
    but dont know if all of them do.

    You want to be careful with things like windshield washer reservoir, and the
    vacuum cannister, which could be damaged if you lose grip, slip up, etc.
    (I once broke the plastic hose nose off the vacuum cannister and ended up
    taking it out, drilling, and fitting a metal one.).

    The back plugs are still sometimes a little hard to see and get onto, but if
    you
    have a decent set of wrenches and are patient, you can do it.  Be careful
    you
    don’t cross thread them when you go back in.  Since you may not be able
    to see or feel them out easily, go easy until you are sure you are right.

    This is from memory, as I haven’t done it in a while, but I think that if
    you
    work carefully and thoughtfully, you will find it pretty easy.

    Thanks for the help. I would like to disconnect as little as I have to
    and I may just take it to the shop anyway it only costs me about 75$
    don’t know how they do all that work for such little money.

    I do want to rock the engine though, just so I get the feel about how
    it goes. But its my work car and if I mess it up over the weekend I’m
    walking to work. I’ll let you know how things go and look forward to
    discussing this more and again thanks for the help.

    The spark plugs will cost you a few bucks each, so less than $20 I would
    guess.

    So they can make over $50 bucks in short order.  If you know what you’re
    doing,
    it doesn’t take long.

    If the plug wires go bad, I am sure they would have to charge you extra.

    It would probably be interesting for you to look around the engine
    compartment
    and see how everything sits.

    You bet I want to change the plug wires myself and save some money. But
    this is my work car and if I don’t get it right over the weekend and it
    ends up in the shop I’ll have to either walk or borrow my wife’s car
    and she hates it when I do that. So I always have to be careful and
    make sure I know what I’m doing. Maybe I should go to a junkyard and
    play, people have to me to do that kind of stuff in the past. Thanks
    for the encouragement I think that’s all I needed, I’ll keep you
    posted.
