Cadillac DeVille



  • sonjaabsonjaab Posts: 1,057
    Did you ask the dealer about the recall that I posted about ? Its a few posts back.
    Took mine in for that emission recall and they zapped the computer while I waited.
  • I have a 1990 Cadillac deVille (4.5 V-8). It has about 119k miles on it. Had the radiator replaced recently. However, I recently noticed some coolant leaking from the left side of the car (drivers side). Can someone tell me which hose might be leaking (upper/lower?). I'd like to have an idea of what is wrong before I bring it to a service center.
    Any help is appreciated, thank you.
  • sonjaabsonjaab Posts: 1,057
    Prob. a loose or bad clamp. Easy fix...Take it back to the guys who replaced the rad.

    Don't forget to ask them if they put in the GM "sealant pellets" when they replaced the radiator. VERY important !

    can any one tell me if they know of multiple bearing failures in 94 deville water pumps. I have replace ours 4 times to date. Last one went 40,000 miles.
  • fjk57702fjk57702 Posts: 539
    My service manager tells me that the northstar water pumps last anywhere from 25,000 miles to 250,000 miles. So multiple replacements are not unusual for a car and some cars never have a replacement.
  • Thank you sonjaab for your help. I do have other questions for you (or any one else who may be able to answer my question).
    I wasn't able to go back to the original dealer who replaced the raditor. I went to a radiator shop that came recommended. They had to solder a side tank. First question: he also replaced the cap. The old one was from the original radiator, it was all rusted. Could this old cap not have been presurizing correctly, thereby causing this problem?
    Also, he added those sealants pellets you spoke about. Could you please give me more information on these? Such as, what are they for, and what could happen if the previous service center did not use them?
    I'm trying to gather up as much information as possible because I don't feel as though I should have had to lay out additional money for something they did wrong.
    Thanks again

    Those sealant pellets have been used for a few years now (88 and up?) in the Caddy alum. V-8s.
    They are supposed to prevent internal coolant leaks in the engine. If memory serves me Caddy calls for 100k miles coolant service and tablet replacement or when ever coolant system is serviced.

    If not used a BIG $$$ repair bill could come later down the road.......

    Most auto parts stores sell the GM equiv. tabs
    Bars Leaks is one and they come already crushed up.

    What year is your Caddy? My 96 and 02 had no rad. cap. Does yours have a copper rad.? Most new rads have a alum. cooling grid and plastic side tanks. Thus not repairable...Well they can be "recored" but too many leak problems if they are not crimped together properly. There are copper replacements aval. tho. but very pricey . Just put a copper one in my buds VW...Almost $400 bucks wholesale !!!!! ..........geo
  • My Cadillac is a 1990. It has close to 120k on it. Mine does have a radiator cap, both the old radiator (original?) and the new one. Not sure if my radiator is alum or copper. Is there someway to tell? It's y probably alum. though. The raditor shop that repaired my new one put those tablets in, so I shouldn't have to worry about a high $ bill down the road. (knock on wood). Thinking I need to talk with another Cad dealer, get something in writing about leaving an old rusted cap and not using the sealant pellets having do to with what happened.
    By the way, how do you like your Caddy's? I like the styling of the 2000+.
    Thanks again for your insight.
  • sonjaabsonjaab Posts: 1,057
    Look at the side of the rad. tank. The newer ones have plastic side tanks.
    Its good to know that the rad. shop put those sealant tabs in tho. Many folks have been burned on that issue.

    90 huh? ...I had one from brand new. Loved that car. It had the Bose CD player. Man that mother cranked ! It also had a ASC aftermarket sunroof.
    Leaked like crazy..Hated it !!!!! But that car went to 130k troublefree miles for me. And its still around too ! I used to BURN that Michelin tire off the corner. Used to blow off my bud in his 5.0 stang ! That pre-Northstar motor would crank.
    MUCHO more guts off the line than my 96 or 02 Northstar Devilles!
    As you can see I love to PUSH on my cars, especially beating down those 6 banger superior wannabee import luxury cars off the corners or hiway !..............geo

    ...had the non-Northstar 4.9 V-8. Boy that engine was a powerhouse! That car went to 100 MPH with absolutely no effort.
  • sonjaabsonjaab Posts: 1,057
    Hows that Seville doing ? How about that Impala?

    Have ya seen the ads for the new Impala SS?
  • lemkolemko Philadelphia, PAPosts: 15,294
    ...are doing just fine. I've seen the ads for the Impala SS and am rather disappointed. I'm more impressed with the Caprice patrol car in the ad. Now, if that Impala was a V-8, I'd show some serious interest. As it is, it's just a silly graphics package and hardly any performance improvement over the 3.8 Impala LS.
  • sonjaabsonjaab Posts: 1,057
    I thought they were supercharged? Hmmmmmmmmm

    Nice day today anyway..Gonna wash the Caddy.....

    Then go riding the jetski in the beautiful 1000 Islands NY !!
  • I know what you mean about the pre-northstar caddie engines. Don't let the 180-HP rating fool you :). Torque rating is at 240, which helps launch it off so quick. Off-the-line power IS tire smoking, and these cars certainly can hold their own. By the way, I notice you're from NY. Me too. Originally that is. Brooklyn born and raised. Then lived 18 years in Staten Island. Now I'm on the west coast, and missing that food. Have fun this weekend.

    VERY NICE!!! I loved the wood trim (unfortunately, no wood steering wheel or shifter; we had a six passenger). The seats were AMAZING!!! The front seats were 5 feet thick and the rear seats were indescribable. This is my favorite sedan under $60K. At a dealer, I saw one with the wood steering wheel and shifter and they were WAY pretty. I imagine the DHS and DTS are even nicer than the base, although that is hard to imagine. I know DTS stands for Deville touring sedan, but what does DHS stand for? I didn't like the digital gauges, though, I wish Cadillac instead had those beautiful white-faced gauges. The digital ones remind me of a Suzuki Aerio and 80's cars/trucks.
  • barry45rpmbarry45rpm Posts: 98
    DHS stands for "Deville High Luxury Sedan"...and yeah, that digital cluster makes the whole car feel like a cheap a piece of cr@p. What the hell were they thinking? ...and no matter what the brochure says, the car isnt a 6 passenger car. That center front seat is so hard, the head of the kid unfortunately sitting there sticks out thru the sun roof. It would probably be better to just have a 60/40 seat like the old days, if they really wanted 3 across in the front.
  • libertycatlibertycat Posts: 593
    Adults comfortably sat in the front center seat with no complaint on fairly long trips. Plently of room for them and VERY comfortable.
  • barry45rpmbarry45rpm Posts: 98
    How could it be VERY comfortable? It is no more than a plastic lid for the hidden console under it, with a quarter inch of foam rubber laid on top of it, covered with the leather seat skin. There is NO "give" to it and certainly no cushion to it. It is definitely NOT a seat in the way other 6 passenger cars are. I wouldn't want to go further than to the Mall on it. Its a "bleacher seat" in the midst of "sky box" lounges. If you look inside the console, you will find compartments to wind up and hide the (rarely used) R & L seat belts & buckles for that seat. Even Cadillac doubted that the lid would be used as a seat.

    Are you missing something. My 2002 DTS has the digital cluster but it also has the option of a neat analog speedo and tach. Just have to push the mode button on the dash.
  • barry45rpmbarry45rpm Posts: 98
    You DO have the option of switching back & forth as I do. However the digital cluster on the BASE Deville is HUGE, and features a 2 inch high, 3 digit LED readout centrally and on the right a 3 inch tall green fuel gauge, & on the left a 3 inch tall green water temp gauge. That is all you get. The button you speak of in this case turns the water temp & fuel guages on or off. UGLY green cave drawings on a black background. The cluster we have is simply beautiful. And appropriate for a car in this price range.

    Back in the 80s and early 90s I loved digital instrument clusters, but I think the Seville and DTS/DHS electroluminescent clusters combine the best of both and they look great. I love how the cluster is dark until you start the car then the needed glow red and sweep the dial.
  • libertycatlibertycat Posts: 593
    Adults sat in it fine for us. They and I thought it was VERY comfortable and roomy on long trips. I don't understand why u don't agree.
  • lemkolemko Philadelphia, PAPosts: 15,294
    ...has the dual electroluminescent analog/LED digital display. I have my car constantly in the combination mode.
  • Are you able to turn off the analog display on your Seville, or just turn off the dig?
  • oldsman01oldsman01 Posts: 1,203
    I had an SLS as rental for a week last summer and with the instrument cluster you could switch to (1) regular analog style gauges, (2) regular analog style gauges with a digital readout of speed in the top center part of the cluster, or (3) gauges dark with the digital speed readout being the only thing displayed. I kept it on setting 2 as I liked have the digital readout give me the exact speed(espeically since I was an out of towner) and it was also fun to watch the speed jump in increments of 5 or so when taking off from a stoplight. I'm not sure why anyone would use the digital speedo only setting as it just didn't look right. And the full cluster just looks so much better.
  • lemkolemko Philadelphia, PAPosts: 15,294
    ...the analog display as well as the digital.
  • barry45rpmbarry45rpm Posts: 98
    Evereyone agrees that the ability to choose between the 2 types of displays is neat. However on the base Deville all there is, is the giant green digital speedo/fuel/& Temp scales. Huge green things on a largely completely empty black face. Cave drawings! Besides, did you ever notice that with an analog speedo you always know just about what speed you are travelling by the vague peripheral area of your line of sight that the the red pointer is hovering at... With digital, you must drop your eyes, READ and understand the exact number, since the numbers are always in the same place. And is it THAT important to know if you are going 62 OR 63 MPH? Remember guys, you are turning the digital part on sometimes for a period of entertainment...and then you turn it off for a serious instrument cluster. A base Deville owner has no such option.
  • I understand what you're saying about the dig display and how the 94 and newer base deville's only get the large empty black face, however, pre-'94 displays were shorter, and had the fuel display off to the lower left side, and therefore they don't look as "cave drawing" like. My deville, a '90, has the dig display, and I myself, prefer it over the analog speedometer, (the huge one from left to right, only other dash available) that only went to 85. I don't know about everyone else, but I like to know how fast I am going past 85, and also find myself able to glace down and recognize my speed in a second's time. I'm going to look at a seville sometime this weekend and check out this dual display everyones talking about. Analog is nice, but only when it's a real speedometer that registers at least 120. :)
  • oldsman01oldsman01 Posts: 1,203
    I remember those old speedos that stopped at about 85 MPH. Nothing like a car that was designed during the era of the double nickel national speed limit. I've gone above 85 in my Intrigue so many times that if it's speedo stopped at 85 it would probably be broken by now. BTW, those old Caddies(80s and early 90s) with the digital speedos, did they really go above 85 MPH. Some older Ford and Chrysler cars with digital IPs were not calibrated above 85 MPH and if you were going faster than that(scary thought in some of those cars) it would just blink "85".
  • fjk57702fjk57702 Posts: 539
    I only use the analog display on my Seville. The digital readout is above the gearshift indicator, which is barly readable, so I have to bend down to see the digital MPH display. The gearshift is clearly marked on the consol, so the electonic display is not needed.

    My 84 and 86 Corvettes (with digital displays in color) would go beyond 85. The analog part would shift its pattern though, so you had a more precise display up to 55, and then a more compressed one above that. I once got the 86 up to 185 kilometer per hour, was trying for 200 but a curve in the road came up.
