    Replace Spark Plug Wires?

    I was talking to a service writer about new spark plugs and he suggested that all the spark plug wires be changed at the same time. This seems like an unnecessary expense that isn't called for in any manual I can find. Other than mileage, the car is
    running fine.

    I'd like one of the technicians or customer service people to give me their ideas on this subject.

    Thanks,

    Chris

    Re: Replace Spark Plug Wires?

    I am not a Cadillac technician, nor do I play one on TV...But I did stay at a Holiday Inn the other day.

    I see no reason in the world to replace the wires.
    The Cadillac uses Coil On Plug and if the wires are not damaged and if it isn't missing and if there are no codes relating to the ignition...
    My opinion is someone is just trying to make a little extra money.

    My DTS has 110,000 on it and is still on the original plugs with no issues.

    Thanks Jim. I'm beginning to think that NONE of the "company" people want to touch this question for exactly the reason you mention..... It wouldn't be the first time that someone wanted to 'pad' a bill, and I guess no one wants to rock that boat. I may just take my Cadillac service to someone local rather than the dealer!

    Did you go to the dealer that I use?
    I think you know who that is.
    I haven't had much of a problem with them... but I always go to BRUCE...
    He has known me for a number of years and knows there isn't any use of trying...

    I would be more than happy to call him for you and let him know that you just want the plugs changed and THAT'S IT...

    Re: Replace Spark Plug Wires?

    plugs are supposed to be changed at 100,000 miles ...

    there are no wires on N* engines since 2000

    you only need to replace the boots on plugs that have been misfiring and have carbon tracking on the inside of the boot

    Re: Replace Spark Plug Wires?

    Thanks Chris H., and when I mentioned that I had looked at a service manual diagram for my car and that I didn't see ANY plug wires since the coil
    sits on top of the plug, he said, "it's the wire leading to that coil that needs to be changed!" And YES Jim, it's the same dealer, and NO, I won't be
    having any more service work done there. I've used them for almost three years since moving to Texas, and I'm rather disappointed by all this!

    I really hate to hear that...
    I would really like to have that service writers name.
    If you are not comfortable with posting it here... can you PM me his or her name?
    I "FOR SURE" don't want him or her "EVER" taking care of "MY" car.

    Chris,
    I am the tech manager at Autolite spark plugs. I am also a technician who owns a repair shop. The guy is giving you good advice for a couple reasons. The cost to replace the wires is lower when the plugs are changed because they have to be removed. The plug wires do get old and crusty from heat and ozone. They can frequently crack upon removal and then cause misfires later when the crack is big enough for the spark to follow a different path to ground. Imagine you buy the tune up (plugs only) and 6 months later the car is misfiring due to a bad plug wire, no th expense is all over again. I always tell people in my shop when replacing plugs that I will usually need to replace the plug wires if I decide they need to be replaced. They just cook themselves onto the plugs and the boot will rip when its removed.

    Chris,
    did a little research since my first answer. Your car is coil on plug with no plug wires. many of those types of systems do have a replacable rubber boot between the coil and spark plug. On your cadillac, that boot is moulded onto the coil. He was selling you something that doesnt exist.

    Re: Replace Spark Plug Wires?

    You Know since buying Gm cars stating in 1968 I am not a real big booster of GMs service dept ( I also worked in a cadillac dealer parts dept. a couple years before.) but the service writer is correct do it once right. It would be wrong for him not to mention boots/wires and if 6 months later if you developed a ign. problem you would really be upset with the dealer/service writer. They are not all scam artist you just have to know what to look for and be a member of this forum.Mike

    Re: Replace Spark Plug Wires?

    it's possible he was just ignorant and didn't know that your car doesn't have wires

    it's also possible that he knows the difference but assumed you didn't and was trying to 'dumb it down' for you

    the only way to really know if you were getting 'hosed' is to compare their estimate - labor & parts - to other places

    if they wanted 5 hours for the job and the book time is 3.2 then yes, they were 'hosing' you
    if they wanted to charge you $15 per plug then yes, they were 'hosing' you

    maybe their labor rate is $120/hr ... maybe they had all 8 plug boots on your estimate

    it seems a bit high for the job, but i'd have to see the exact items and times on the estimate to know if you were getting 'hosed'
    that said, if you were getting 'hosed' it wouldn't seem by much

    Re: Replace Spark Plug Wires?

    THANKS, all of you! I will go back to the dealer and give them a chance to explain in detail what they are suggesting. I didn't just fall off the back of a turnip truck; back in the late 1950's, I went through technical training in Tune-up, Brake systems, and other areas that now is called "ASE Certified!" I haven't worked in that arena since I joined the Air Force in 1960, but I do recognize when I'm being "led astray!"

    Thanks again,
    Chris

    Chris...
    I will be more than happy to call my service writer for you..
    He (Bruce) won't jack you around and try to sell stuff to you that you don't need.
    I also know the Service MANAGER...if that helps any...

    I feel bad that I recommended them to you and they did you that way.

    CalDrvr,

    You said that the personnel in service suggested you replace all of your spark plug wires. This was just a suggestion to keep your vehicle running in top form; this was just a precautionary suggestion. I hope this helps!
