Drivendeville, that is the highest mileage I have ever seen on any Northstar. How many miles did it have when you bought it? And did you name it?

WOW, thats impressive! it looks like you do not live in the rust belt, but what i would like to know is what you have replaced on the motor and tranny? that is allot of wear to put on them kinds of miles. Maybe you have already posted this, so maybe a link to it? Thanks!

Blew head gasket at 280k so bought a yard engine with 65k from an 02, pulled the heads, studded then installed. While cradle was out replaced entire poweresteering system, front and rear wheel bearings, all rotors and calipers, 3 brake lines, control arms, drive axles, struts on fron, tradiator, condenser, ac compressor,all hoses ac and coolant, both belts, both tensioners, and a 90k trans( which failed in 128 miles). The original trans was working perfectly, just swapped it out since cradle was out. Long story short, had a shop put in a Jaspers rebuild, failed in less than 100 miles. They would not stand behind the labor warranty so I was stuck with another $750 for labor, the new rebuilt lasted about 30k miles. This time they chose to honor their labor warranty (!00k or 3 years Parts & Labor). While i don't feel they stand behind their warranty the way they should, as all the labor on the 3 Jaspers transmissions was performed by one of their approved shops, they did supply replacement units quickly. I wouldn]t do business with them in the future, I was within a millisecond of suing them if they didn]t cover the labor on the 3rd unit. The last unit shifts a little hard sometimes but I don't believe they have the skills to rebuild a 4T80E. The rest of the rebuild has held up fine so far.

Over half a million mi. is very unusual for a N engine (or any engine) but for the rest of us its not if but when those HG are gonna give up because as I understand they will blow..And nobody on this forum can tell you when. But on a long trip it will be constantly on your mind. Cadillac engineers should have been on top of this one but just like the caddy diesels the customer has to be their proving ground. I had a diesel Cadillac and it was a nightmare.I used to leave the keys in it so somebody would steal it but no such luck..This will be my last Cadillac. Their nothing but money pits.(at least the older ones are) not sure of the newer ones but I dont worry about newer cant afford them..So for those of you who have had good luck (so far) I'm happy for you. And for those who have had the luck that I have had you have my deepest sympathy..Iam 77 yrs old and apparently havent learned my lesson yet. Yes Im too old to work on this car anymore and I have to pay to have it done and my pockets arnt that deep anymore........................98 Deville 160,000 mi. Oh I still like it though...

Is this engine still intact for all these miles? What major components have you replaced? And how is the transmission holding up? Do you use an oil additive? My '96 STS is at 426k...transmission went out at 377k.....just curious about your experience! Thanks,STS777.

Submariner409
10-18-12, 01:54 PM
Are you still under the impression that there is anything wrong with properly maintained DEX-COOL ? Your question would appear so .........

Here's 2 quarts of 50/50 DEX-COOL from the truck engine with 88,900 miles on it (the engine) - the coolant is 3.5 years old. Just changed it all. Look like anything wrong there ?????

It looks beautiful--almost good enough to drink! (edit: make sure to put skull and crossbones on it if you have any children in the family). Alas, I'm not concerned about the coolant itself more so than the head gasket. Tearing the engine down and looking at the head gasket would give a better picture of how well it is protecting it.

The silicates in conventional green coolant coat carbon/carbon composites [graphite composite headgasket] and are used to make it oxidation resistant. Dex-Cool is a silicate-free coolant. It is wonderful in protecting aluminum, brass, cast iron, steel and copper, but offers no carbon/carbon protection. Our composite head gaskets are made of graphite (carbon), copper/brass, and felt, and a good portion of them are soaked in coolant.

Other large manufacturers saw this protection void (and the lawsuit due to deterioration of silicone rubber and nylon gaskets), and opted to add silicates to their versions of long-life coolants, and they are now called Hybrid organic acid technology coolants. The added silicates coat and protect what the potassium 2-ethylhexaonate (hexaonic acid) doesn't. Toyota, Honda, Ford and probably others use this type of hybrid coolant. They prohibit the use of anything else, quite emphatically in some instances.

How many 93-96 Northstar's have HG failure vs 97-99 before the better headbolts? They are otherwise virtually the same engine--are they not??

**edit: I'm not saying that there aren't any failures on 93-96 or that the observation negates the other flaws such as torque-to-yield head bolts, or a flaky gaskets. I'm saying those head gaskets may be very vulnerable to fail in as it is with all the expanding and contracting cycles of the aluminum or the graphite and the steel bolts... The straw that breaks the camel's back or rather precipitates the failure could be a coolant that lacks corrosion/oxidation protection to graphite. A renowned polymer expert I work with confirmed it for me: graphite does in fact corrode/oxidize readily if uncoated, it burns or flakes.

Well the STS I just got in October is ar 138000. The only engine issue (knock on wood) is the front valve cover leaking oil and I need to replace the oil pressure sending unit.I have replaced the fuel level sensor,both outer tie rods,right front hub,replaced the EBTCM.
I was really second guessing the purchuse of the 2002 STS. I had sold my 1994 Fleetwood Brougham ,after I had a fellow that wanted it more than I did,and I ended up buying this STS. So far after spending a little time and money to get it to a nice daily driver I am very happy with it.It does n ot come close to riding like the Fleetwood,but with the FE-3 and F55,this car almost feels like it is on a rail. Living in the BlueRidge Parkway this car is a blast on the mountain roads,it is hard to believe that the 300hp can get up and go in this size car.
So far I have made one 1000 mile trip and was only able to pull out 23 on the open road. The worst part is the Fleetwood with the LT-1 I could get 26 with no problems. So I am hoping that it will get better,but still with 300hp and 23 mpg I am a happy camper

Submariner409
11-21-12, 12:46 PM
Long highway runs using 87 octane should get you just about 24.6 - 25 mpg. That's what I get on Shell 87 between MD and FL on I-95, running at 80 - 85 a fair part of the way.

Check the air filter (WIX), the band clamps on the intake ducting, and the correct placement of the air intake resonator. When were the AC Delco #41-987 plugs last changed ? Is TCC engaging ?? - - - flat road, 60 mph = 1980 rpm in D.

Look in my albums for hints on how to get rid of that stupid resonator plus other stuff.............

You're gonna think I'm crazy, but simply changing an apparently perfectly fine fuel pressure regulator netted me another mpg.

rocketvette95
11-22-12, 11:59 AM
I am going to replace the plugs when I recieve the valve cover gaskets within the next week. I did replace the air filter with a Fram extra Gaurd
I did check the F/P regulator and there was no fuel in the vacum line so I just marked that off of the list.Now as for the gas I have been tying to run Exxon regular for about 90% of the time. If I am in town that is all I will get and from the same station.When i make the trips to the eastern part of NC I try to get most of my gas from Sheetz. I really think that all the 10% Ethonal that is in gas is what is killing gas mileage!

2001 cadillac dts: 165000 miles no problems

2001 cadillac dts: 110000 miles getting the motor studded at the moment (this ones caused me more headaches then the others combined)

2004 cadillac dhs: 60000 miles this one has been the most reliable hands down but then again it's very low milage

As you can see I love devilles I wouldn't drive anything else I test drove a xts just isn't the same I like my devilles more. These cars are reliable if you take care of them if you don't that's when you start getting problems with them.

2001 Deville 169K I did the head gaskets earlier this year with Norms inserts

2001 Deville (a twin for above) 139K

2005 Deville (Mary Kay pink) 90k

Also had a 1998 Deville (replaced head gaskets) and a 2002 Deville with only 50k on it, traded it for the 2010 DTS Lux. Great car, doesnt feel quite like the older Devilles do though.

I have a 2000 Deville with 228,000 miles on her. I do have some significant problems, however, and I am reviewing if it will be cost-effective to replace the transmission and motor. I've found a shop that replace them for 1,500

For the past 10k, the transmission overdrive solenoid has been out (throws a code on the dash)
I was informed by my mechanic that I have a 6 inch crack in the block, which he felt was likely from a pothole. He said that this was not all that uncommon. I never ran it hot, though it did momentarily spike, before I could get off the highway (Camel mode never came on?!?), and now I also apparently have a blown head gasket. I replaced the thermostat, which may have been sticking, and caused it to run hot/hotter before replacement. She runs kinda ruff, but still chugs along, and I can drive around town - at least during the colder weather. If I am faithful to make sure the overflow tank is full, I can drive about 40 miles on the interstate, though it sometimes starts to climb going over a mountain that I go over. I am pretty sure that she will begin to consistently overheat when the weather gets warmer. I am blowing gas into the coolant (verified at a radiator shop) but it seems to be clearing off the excess heat, at least for now.

Yea, I am 47 and this is only car I ever got for free lol. I spent a total of 1500 bucks on parts and 20 hours of my time. I could have left the rack alone, it was just barely seeping but since it was right there staring at me I went ahead and replaced it. It'll need tires in a few months but I won't mind paying for them. Heck I don't care what goes wrong with it, it'll be worth it to me to keep it running the next 20 years lol

182K on my '97 STS.
Up to 6 months ago it was all untouched power train, since the engine was pulled 3 times and the transmission was replaced twice.
It all started with a winding noise when shifting until eventually it was slipping and winding all the time.
Finally the 3-rd time when the engine was removed the transmission was replaced with a new GM unit and hope for the best.
Ah...and since I did not wanted to go again trough another engine removal I decided to stud the engine for absolutely no reason, it was holding just fine but is safer now. The bottom end was resealed and the timing chains and tensioners replaced (one of the tensioners was worn all the way to the metal). That's about the only thing worth to be mentioned with the condition of the engine.
Engine awesome, transmission pretty disappointed as it lasted only 175K and it was really well taken care of (I mean REALLY well, never ever abused, fluid/filters changed 3 times).

Ok - I just found this thread and joined the forum just so I can reply to this. My 2004 deville has 217,700 on it currently and I do NOT consider this high at all. The day I bought it with 62k on it I fully intended on taking it to somewhere between 350k and 400k before selling it still running good. EVERYTHING with a northstar has to do with proper maintenance. I use Mobile 1 Extended performance 15k oil and change it every 6k to 8k miles. Don't use fram paper oil filters - use the supertech from walmart or the Mobile 1 filter - both are very comparable actually as they are fabric, high-flow filters. Switch to the K&N air filter, change your fuel filter every 30k to 50k miles, flush your anti-freeze/coolant every 60k miles or so but IMMEDIATELY get rid of the Dex-cool (that's first priority - did it at the dealership day I bought mine and replaced with Prestone Global). Change your plugs using original iridium plugs every 60k to 75k miles. At 9 years old and nearly 220k miles my car is literally as smooth as it was the day I bought it and looks new in and out. I can look down into the oil fill and the engine look as clean as new inside. There should be absolutely no reason to not get another 150k out of her. Take care of your cadillacs and you can drive them about as long as you'd like. I still get the same gas mileage that I did when I bought it (which with the air filter and fluids listed above is 31 mpg highway at 70 mph). I floor it routinely to keep the carbon out of it as well about once every 2 weeks taking it up to 90 or so very briefly (from current highway speed - never from stop or lower spead as this is aweful for a car). Also, the use of a fuel injector cleaner is extremely helpful - I use Lucas Oil for this every 3rd fill-up and only use good quality fuels. I also strongly recommend changing your transmission fluid and steering fluid every 60k to 70k miles also and during this I add 2 quarts of lucas trans fluid (normally 1 but the pan on this transmission is an 18 quart pan). The 4t80e transmission will ALSO drive as long as you want to drive it as long as you change the fluids and treat it well. I should point out that this is the routine I use on all of our vehicles and we almost NEVER have any car problems and I strongly recommend it. I think that Amsoil would likely be as good or better for any of these fluids, but I've had a working process with easy accessability to the ones I use so I've stayed with the ones I currently use. I LOVE cadillacs - have all of my life, grew up with them and have seen even models that were considered garbage run fantastic for years and years (mid-80's 4.1 - never had issues with them) when maintianed well.

Guy I work with has a Seville STS. 02 I think. His dad was the second owner and bought it with 50k and now he has it. Its been worked on of course but to his knowledge no head gaskets. I think a couple starters and altinators and most recently rear suspension conversion (I guess without sensors tops out at 90 mph). Last talking to him he said 260k but I'm guessing it's got to be closer to 265k now with the distance he drives to work. Original window sticker in glove box says $53,000!! Original owner was a doctor and paid in full. My window sticker says $45,000 on my 01 Seville base with back-up sensors and floor at package. (About 3k in upgrades from factory.)

It has been years since I actively participated at this great site. I wish to report that my 1997 STS became INOP in 2008. She gave 190k total miles with original motor and trans. In 2005, I purchased the vehicle for $1.5k from a Cleveland dealer, and with approx.150k miles. It was nice run.

If not for CF, I don't think she would have lasted as long. This site offers much useful info and advice. Special thanks to CF Mods and Members.

Didn't really want it when I bought it, just helping out a young military member who couldn't leave until he sold it, but now it has become my daily driver. (minimum of 100 miles every day) It had just over a 100,000 when I got it and now is sitting at 187,377. There is no way that I would still have this car without the constant help of this site. The car had a bunch of little things wrong when I got it and because of this site I was able to overcome MOST of them myself, this site has probably saved me $2,000 in labor. Thanks
