    Cadillac has 200,000 miles, i feel like i should replace certain parts

    My 2002 Cadillac Deville has 200,000 miles on it. I am afraid there are certain things that will go out and it will be a hassle to fix when it is not working.

    The crankshaft sensor, EGR valve, and Bank 1 coils have failed and was replaced. I already replaced the Alternator (it didn't fail, but I replaced it when the radiator needed to be replaced).

    Now I think I should replace the Camshaft sensor, Starter, Bank 2 Coils, and the fuel pump. I would rather replace these when it convenient, than when they actually fail and the timing is bad.

    How many miles do these items usually last? I would think they can go bad anytime after 100,000 miles. And which ones would you replace first?

    Thanks

    Any electronic part of your car could fail today, 100K from now, 500K from now, or never. Mechanical parts, such as the starter, there's no set mileage or age. You could come up with $15,000 worth of work that needs to be done if you start naming things that "might" fail soon. There's really no answer to this question.

    Belts, pulleys, tensioners, hoses, plugs... Any of that been done in the last 100K?

    MC is right. Check the things he listed. Perhaps check suspension components as well. Brand new electronic parts are just as likely to fail as the ones on the car now. It's a gamble either way.

    The list of potential replacement parts is endless. It'll let you know when it's time to replace something just like it did in the first 200K. If it ain't broke, don't fix it.

    As an avionics tech for the USAF I can attest to the fact that a "brand new" part is just as likely to fail as one that has been in service for years. Hopefully a part will give you some notice before it goes out on you. More than likely, you will repair it after it breaks.

    I would even suggest that a replacement electronic part is more likely to fail.
    Many aftermarket replacements are not the same quality as the original.

    I used to frequent a salvage yard that advertised: "All our parts have been road tested--unlike that new one in a box"

    I think you have proably gotten the idea from all of the suggestions posted. Forget about replacing electronic components and focus on the mechanical items - they will all wear and eventually need replacement. Also, don't forget the liquid systems and misc items like vacuum lines, spark plug wires, fuel filters, fuel injectors, etc. You are asking the right questions and having your vehicle on a preventive maintenance schedule will eliminate most on the road catastrophies.
