Well the plugs at the dealer are around 8 bucks a peice, napa is around 4, the wire set is about 180 at the dealer, I know its alot but that is where I would buy the wires from, plugs go to napa, putting cheap parts on that caddy will cost you later. I would do the wires and all plugs, and then wait till it rains and see what happends, if it still does it replace the crank sensors, and a relearn will have to be done at the dealer
headgaskets: yes they are bad about it, if it overheats do not drive the car, shut it down and get it fixed. most people continue to drive it, thats why they have problems, and its not the headgaskets that go bad its the headbolts, they pull out the threads when it gets too hot, then they need helicoiled, I had a 99 Deville it got 25-30 mpg thought it was great. Would I buy a caddy yes I would [/quote]
Ok, I think I can do the tuneup myself, if I can get to those back plugs. Any special tricks? I suppose since it has no Distributer, theres no rotor bug or anything other than those crank sensors and relearn that you mentioned.
I worry about messing with these plugs, as I had a friend who tryed to change plugs from a old Plymouth with aluminium heads, and they were so rusted in, that he messed up the threads in the head. Maybe I'd be best off to let that mechaic do it, or take it to the local Chevy dealer, as we don't have a Cadillac dealer nearby. (The Chevy dealer cut me a spare key for it for 21 bucks total, and I was told they would charge me 85)
Oh ya, did those codes tell you anything? I am dumb when it comes to "computer" cars, and I dont even know what codes are.
I hope I can get it all straightened out, because we are taking a trip the first week of June to Michigan to visit my wife's mother, around a 650 mile trip one way, still I'd hate to break down somewhere I'm not familiar with, and I'd hate for her to make me drive her Cavilier, as I said I'm 6'3" tall, sucks to drive bent over.
As for overheating, this car has NEVER ran any hotter than 205, usually it runs at 189 is that a good temp? The mechanic told me that was normal.I noticed on my reply to that other lady, that you are not a fan of those pellets, my friend told me to crush them, and disolve them before putting them in, so maybe thats why I had better luck, also thanks for warning me about those bolts, that sure eases my mind, as I know that Head gaskets are a fortune on most any cars, much less a Cadillac. Do you think he was correct to advise me to leave that Green Antifreeze in as well? Cadillacs manual seems to demand the red stuff, "Dexcool" but I've noticed some antifreeze says "works with any color" YET I seen some Prestone that was more expensive that said "meets Dexcools requirements" But as I said, its NEVER overheated, and I cant see the full mark on that weird radiator/overflow all in one, and I filled it to the top, thus causing it to dump out the excess, thats why I smelled antifreeze back then, my own fault. Now it doesnt spit any out, and doesn't lose any, also no white smoke.
I don't know if its me or what, I've read the book, but I have troubles with the Heater/AC controls. I wish it just had the old time kind, AC on Heat on etc.. I can't say, force the AC to run, but when it got to 78 a few weeks ago, it worked great, but say it's 70 outside, I cant make it blow thru the vents and blow cold. In fact when I bought it, I had to take that guys word that the AC even worked. I guess I'm just stupid to this "Climate Control" thing. I had a 1968 Olds 98 many years ago that had climate control, but it also had manual controls like most cars.
I'm glad you too like Cadillacs. Do you think I got hurt buying this? I paid $4100 for it, and it bluebooked for alot more at the time. (Jan 2008)
Hey man, I want to give you points etc for answering me, but I tried and it wouldnt let me, it said "You cant give more points than you have" Just want to give you a good word here for helping me.
Take Care, Jack
you shouldnt have any probs doing it your self, just remember to take your time and do the spark plug wires one at a time to get them in the right places. the spark plugs will come out easy dont over tighten them going back in, just snug.
Yes some green coolant meets dexcool standards, its safer for animals
I believe you got a steal on it, and hope its a good car for you
