Cadillac DeVille



  • trainiac1trainiac1 Posts: 13
    I wouldn't buy a new one, STS, since I don't really care for the look. The one I'm interested in is a 2003 STS, loaded, Pearl White with a beige top. The problem is that my 98 De Ville runs so good without problems, that I hate to give it up. The STS is a little cramped for me. If you go to a dealer they will tell you to recline the seat so it feels as though you have more leg room, but you don't. Always with the gimmicks!!!! No rush, we'll see.

    I have a 1990 Cadillac DeVille with about 86,000 miles on it. I bought it from someone who seldom drove the car obviously. However I have had to put a fair amount of money into the car. The mechanic told me that some things that have to be fixed include:

    - Transmission mount

    - Exhaust manifold

    - Struts & shocks

    The car also leaks quite a bit of oil and I am told that to fix this would be very expensive.

    Anyway, I want to sell the car and am wondering if these things should be fixed first, and what a fair price would be?

    Thanks for any help.

    If the exhaust manifold is leaking that could be dangerous and so should be first. Not sure about the rest. How much oil do you have to add? That might not be worth doing.

    That 90 has the pre N-star engine 4.5 0r 4.9 ? 180 hp. I had one and it ran like a
    bear and troublefree for 6 yrs. and 120k miles.

    Your not talking a dealer mechanic are you? Sometimes all those service guys see is BIG $$$ on a older car repairs or don't want to mess with it.

    Tranny mount...Hmmmm........Cracked manifold.......Bad exaust pipe donut gasket maybe?...Muffler shop will check for free.

    Are you showing any trouble codes ?

    I am a current Cadillac owner and have had DeVilles befor. The most recent was a 93' new program car.
    I am getting rid of it only for upgrading and getting a different col;or.
    Can anybody tell me what I can expect for future problems or noted known resistance if any?

    Would like to here from any one about this car.

    2000 Northstars are known for having the Crank Position Sensors (there are 2 of them) fail. This will kill the car dead in its tracks, at speed......

    If you can research the car's service history, try to see if these have been replaced. If not, if the car suddenly dies, then re-starts immediately, without setting any codes, it's these sensors.....

    I appreciate your comments. It is really tough to get rid of my SLE with less than 100 miles on it but my wife likes it and since she is a realtor and spends $50 everytime she fills up her Avalanche she plans on driving it. I'll wait till fall and order a new 2006 Malibu Maxx and get rid of the 2001 Malibu. The Maxx rides like a Rolls Royce compared to the SLE convertible but my 2001 still has a nice ride after 75k miles. The ride does improve on the SLE though the faster you go on a smooth highway. I don't really like Toyotas but was thinking about the Avalon since the dealer would then cut me a deal with the SLE but I really like the ride of my 2003 Deville and don't really want any stiffer a suspension. The Deville only cost about $27k in January of 2004 because it was a Certified used one and has a great warranty -much better than a new Cadillac. I'll probably replace it in 2007 with a 2006 DTS. I'm glad that you agreed that the ride was lousy on the convertible. I thought that I was the only guy who ever had anything bad to say about the ride. Every car writer without exception praised the "smooth" ride. I don't know what they had driven before -perhaps an Echo.

    I've been reading the posts and saw the replies you were receiving. They are just two completely different cars. The Cadillac DeVille is one of the largest and most soft riding cars out there. The Solara, with a stiffer suspension and shorter wheelbase offers a completely different ride, one that I didn't care for coming out of a DeVille myself. I preferred something stiffer than the DeVille but more forgiving than the Solara. The Lincoln Continental was perfect for me, but they aren't made anymore. Avalon was a great compromise to me. I am new to the Toyota product line so I am not a diehard fan...yet. But I like what I've experienced so far. One favorable attributes of the Toyota(s) that I'm seeing compared to domestics is much higher resale values. In the event you do decide to dump the Solara, I suspect you'll do okay getting out of it compared to a similar situation in with a domestic car. However, if the bride likes it, keep it. That's a battle not worth fighting...regardless of the ride! ;) Good luck!

    I drove the top of the line Avalon and it rides very well. Unfortunately as I said, my wife doesn't want to turn in the SLE. I may be able to convince her to get rid of it this fall when I get a Malibu Maxx. She refuses to get rid of the '04 Avalanche either. We have four cars for two drivers and the Avalanche gets lousy mileage. Actually I probably should have driven the new 2005 Mustang convertible before I got the SLE. I've rented Mustangs before and never had any problem with the ride. Too late now unfortunately to make a switch.

    I just recently purchased a 2000 Deville DTS with 67,000 miles at a local dealership. I was just wondering if there are any unforseen problems that I might encounter with my ride??? Any information on this topic would be a great help.
  • nvbankernvbanker Posts: 7,285
    Yup - you're gonna blow a head gasket at about 75,000 miles, sorry to tell you. They all seem to do it. Also, you could have problems with the head bolts when that is repaired, so make sure you use a qualified shop for the repair. You got a warranty, didn't you?
  • bolivarbolivar Posts: 2,316
    Change the coolant now.

    Use the long-life, 'orange' coolant, as recommended. (Do not use 'green' coolant.)

    Put in the 'pellets' that Cadillac recommends. There usually is a sticker on the plastic cover at the front of the motor that gives the GM part number for these. Put 6 pellets into a radiator hose, do not put them into the tank under the 'radiator cap'.

    Yes, Northstars are known to have head gasket problems. Not all of them. Many, many can go 200,000 miles without this happening. Changing the coolant every 3 years or so (even though the maintanence interval is 100,000 miles), is about the only thing that can be done to help reduce the possibility of head gasket problems. The 'pellets' are a sealant for leaks, and may stop a gasket problem from starting.

    2000's are well known for a problem with 'crank sensors'. There are 2 sensors, both should probably be replaced. If they fail, the car will suddenly stop running, stall out. At any speed. The car will usually restart without anything needing to be done. But, a car going 'dead' at any speed is not a good thing. If you should know where the car previously was serviced, at a Cadillac dealership, they can pull all the service records for the car. The crank sensors might have already been changed. A redesign was done on them, so replacements should not fail. If I had a 2000, with unknown service history, I would have the crank sensors replaced.

    It is a complex car, with complex electronics. You may have problems.

    The DTS has, I think, the 300hp motor, rather than the 275hp motor. This is a very powerful, smooth car that will give excellent milage - about 26/27mpg at 75mph with AC going (or better). It can run on regular or mid-grade gas, with probably less power, and you might hear a 'ping' before the knock sensors retard the timing. But it will run on less than premium gas, and will not harm the motor.

    Northstars are also known to burn oil. If you apply frequent 'wide open throttle' (WOT) applications to the car, it will reduce or almost eliminate excessive oil usage in many cases. And it is loads of fun. I'm not talking about driving it on the freeway up to 90mph. I'm talking about getting the car warmed up, and from a rolling start (no need to actually strain the car with a dragstrip start), floor that sucker and wind it out to the 6,500rpm upshifts in the first 3 gears. You will be doing about 95mph at that point. If the car has been 'babied' all its life, you will probably see a cloud of black or brown smoke come out of the exhausts when you do this. Do this several times. Do is every few weeks.

    You are not 'seating the rings'. What happens is 'babying' the car allows the rings to 'stick' in the grooves. And oil will blowby and be burned. WOT will free up the rings and reduce blowby.

    Buying the car used, someone else has taken the huge depreciation in value that occurs in a Cadillac in the first year. Drive this sucker for a few years, then consider it a throwaway. Sell it for a few thousand dollars and move on.

    At 100,000 miles, change the plugs and wires. Use only AC Delco plugs and factory wires. These, especially the wires, are expensive, but aftermarket will probably cause problems (wires). It's then good for another 100,000 miles.

    The car has a very extensive self-diagnoistic system that an owner can access through pushing buttons on the dash and getting readouts on the dash display. There are other places on the internet that will tell you how to enter this 'diagnoistic' process, and tell you what the 'codes readouts' mean. If you want to work on the car yourself, purchase the factory service manuals. Do not buy anything else, it is a waste of money.

    IGNORE the anti GM troll in post #1827 ! His GM hate posts are all over these

    Hopefully you had you Caddy inspected before you purchased it. A wise move with ANY used vehicle.

    Head gasket problems.............HA-HA !!!!!!!!!! Shows ya what some posters DON'T know ! (But think they do)

    My 90 DeVille went 130k miles from NEW and scoffed at repair shops !
    My 96 DeVille N-star went 100k miles from new also and the only repair
    was a new fuel pump at 90k. NO head gaskets either......................
    My 03 DeVille just purrs............................

    I run my Caddys HARD too...........Not afraid of a stop light drag or a WOT

    Ask those Ford boys how much a timing belt(s) change costs in their v-8s
    at 90k. A N-star uses chains that need no replacement !

    Read back thru these forums and see how many N-star head gasket probs.
    you find.........................HA!

    BOLIVAR is correct..........The new electronic gadgets on a Caddy or ANY
    $pendy new luxo barge are complicated and big $$$ to fix.
    But thats the price of admission to the club !!!!!....................good luck !

    or disk version of manual at

    That's who supplies the ones list in the owners book in teh glovebox.

    I've bought manuals from them for cars since 1967.

    Don't know if you'd find them on auction sites on the web or not.

    This message has been approved.

  • I just acquired a '91 Sedan Deville with 143k miles and I have noticed some transmission noises. Predominantly when I accelerate quickly, on the attack the car hesitates for a fraction of a second and then it knocks. Not a loud knock, but you can feel and hear it grab. A friend told me that that is normal for FWD V8s and it was no big deal, but I want other opinions. Please advise.
  • dispencer1dispencer1 Posts: 489
    Sold it today!!!!! -$28.500 in Amarillo. So I lost a couple of thousand dollars but it was better than keeping it. My wife has gone back to the Avalanche -she began to admit that the Solara jiggled and rode stiffly. I bought a 2000 Mustang convertible -Performance red - from a girl at the office. 42,000 miles and it drives like a Cadillac compared to the Solara. Glad to dump the SLE - I liked the Avalon but already have a Deville that is bigger with a bigger trunk and rides better than the Avalon. Will stick to domestics from now on. Whatever I have in the driveway I'll always have one full size Cadillac and one Mustang convertible.

    Was appreciative of your sharing your direct experience with Cadillacs. I owned a 98 Deville and presently own a 2004 Deville with 23, 000 miles on it. I have had few problems with either car so far. The present car may need a tie rod adjustment in that the wheel always seems slightly to the left and the cruise on the 2004 does not function as well as the 98 did even after three trips to the dealer.
    Overall though I am quite satisfied with the car, its performance and comfort. I will admit that the Chrysler dealership treated me better when I owned a Chrysler LHS. But when a car functions well you shouldn't have to spend much time at the dealership. I always did my oil changes at the dealership when I owned my Chrysler but avoid the local Cadillac dealership whenever I can. From what you stated I should with a little bit of luck get a long and enduring performance from my present 04 Deville.

    I'm not a GM hater, George, and Bolivar substatiatiated what I said. For the record, no Ford V-8s use belts, they use timing chains too, so much for your expertise.
  • cappy4103cappy4103 Posts: 48
    Congratulations! It's much easier to move on to a different vehicle when you and the bride are on the same page! I agree, the Solara ride was too stiff for me. The Avalon was a nice compromise, but it's not a Cadillac. Sounds like you did well getting out of the Solara too. I'm sure that I'll buy a Cadillac again, but from a different dealer. Maybe I'll try the STS next time? I like the "sporty" suspension. My DeVille was just too soft for me.
  • geo9geo9 Posts: 739
    Correction NV. Should of posted "yota" uses belts in the v-8s not Ford.
    I STAND BY THE REST OF MY POST.....................NUFF SAID !!!!!!
