Hi I just bought my first caddy a 2000 deville with 129,000 miles on it yesterday. It only had one previous owner and looks immaculate. I don't know much about engines but I know the v8 northstar has caused some problems in the past and I'm really wondering if this car will last me for 3 or more years. It will be used for mostly small city driving ! Thanks again for your time!

----------

Also the car looks to have been garage kept and well maintained ill try and post a picture in a minute

HI neighbor! :wave: and :welcome:

Take care of it and it should last. If you don't know when the coolant was last changed, change it. Probably wouldn't hurt to clean the TB too.

There was an upgrade in 2000 (roller followers, longer head bolts) so it is much more reliable.

Awesome thank you tons! Also it seems to be leaking oil... And when I start it it says service stability system if you or anyone on here has any advice on those two things it would be appreciated!

Hello Rob, I'm the radiator cap guy. As a pro I couldn't believe the amount of overheating posts on this forum that all started with a worn out pressure cap but went for days checking everything but. So along with changing the coolant check that cap underneath well. If it isn't a newer one that's been recently replaced for the love of all holy do it now. This will reduce your help post count 70% in the next six months.

These engines have several common leaks. You'll have to get under it and look, posibly clean it all off, then drive a few miles and look again. The most common are: The rear valve cover (makes a smokey stink that rolls up from behind the engine) and requires moderate skill and tools. The oil pressure sending unit (the small electrical switch threading into the high pressure oil gallery just above the oil filter itself), this will start in the front around the filter and spread under the whole engine. This one is realtively easy once you get to it. The third most likely is the crankshaft rear main seal, this starts between the engine and transmission (the black four bolt plate on the bottom bridges this gap) and spreads rearward everywhere. This one requires engine removal to repare, at which point you should go ahead and do a bottom end reseal where the lower block halfs meet each other as that is the next most common leak point.
Just be sure it's oil and you're not loosing ATF as these trans will burn-out quickly when low on fluid.

The stability message will also have code(s) stored that will point you to the cause. Read the sticky at the top of the forum to learn how to access codes on the Devilles dash.

Hey everyone yesterday I just purchased my first ever car and I decided to go with a 2000 deville! It has 129,990 miles on it but its a beauty!interior and exterior are flawless as well as the engine looks to be well maintained. I had my uncle check out the car and he found it to be leaking oil and when I start it up it says service stability system. He also said it floats more than his wife's 2000 deville. I am really excited to be owning a cadillac as my first car and I'm already in love with it! If you guys have any tips for matinence or anything I should know about the car in general that would be much appreciated!! Also the rear sub was blown before I even bought it so if you have any websites to order a new sub and any tips on replacing it that would help. Thanks again everyone!

You need to determine where the oil leak is at and pray it's not at the case halves, the service stability might be the shocks/struts

Welcome, and i hope you have deep deep pockets to maintain this vehicle

Congratulations on your first car, this is always a milestone in a young man's life. A well used Cadillac, in spite of its' appearance, inside and out, can require costly repairs. But life is a learning experience, I hope you are lucky with this one!

Welcome to the Forums, you will find a lot of useful information here.

Sounds like you need new shocks and struts. Typical for the age. Did you get a warranty on it? Will they fix the leak and suspension?

They gave me two days to test it out and see how I like it and today is the first day! I was obviously not told about the stability system issues or the oil leak when buying the car so I will probobly have some more negotiating to do to lower the price down! Also I got it for 5820$ not including license and registration(how's that price?). Any suggestions on the wheeling and dealing? It's being purchased from a large car dealer (Gary Lang auto in mchenry il). This is an EXTREMELY supportive forum and I am absolutely impressed thus far. I really enjoy the way the car feels when driving and I'd love to start a tradition of buying Cadillacs. I have a minimum wage job at a local restaurant and work with my dad on the side for extra cash so I will have some extra money for repairs and what not but I can't be putting thousands into this car so if that's what expected I might have to take it back which would really suck! Again thanks for all the support!!

Also it does not come with a warranty and I have no idea whether or not they will fix it or just take it back and try and sell it to someone who won't see these problems right away.

If the case halves are leaking you're looking at around $2000-$3000, the engine has to come out, split apart, and a new RTV sealant placed, along with both rear and main seals installed, along with a new oil distribution plate..ask me how i know

Get her up in the air by someone who knows the Northstar, this isn't your typical engine..

To put it in perspective, I just replaced my active suspension on my '99 STS for approx $1500 - parts only. Not sure how yours compares but I bet it is close. Members have gone to passive parts, that's your call. I have no idea what the leak would cost to fix, not knowing where it is.

So if it is the case halfs then definatly return it? Ill try and get it looked at and diagnosed before I go back to the dealer but if that doesn't work out is there any way I myself would be able to diagnose the oil leak myself? Unfortunately I have minimal mechanical experience and almost no experience with cars!

It would be hard for you to locate unless it's really bad and obvious. Typically you degrease the engine at a manual car wash and drive it for a while to look for fresh oil leaking. I have a dye that I put in the oil and look under a black light. You really don't have much time to find it either way. Don't accept some Stop-Leak snake oil fix.

Most case halves just weep and if your's is the case halves and doing so you can live with it for awhile, mines wept for a long time but when i had the engine rebuilt i had the whole engine resealed as well. Again, get her up in the air and take the time to do a thorough inspection to determine the leak point. Not trying to scare you, the Northstar is a hell of an engine and will provide alot of happy miles on the road, but like any 10+ yr old car its going to need maintenance and replacements it's just that this is a luxury vehicle with a ton of options, and like any luxury car, the more options the more parts their is to degrade and/or need replacing. Again, you gotta have a deep love and pockets for these Cadillacs

:welcome: by the way

Please do not double post. I'll merge your two posts.

----------

The leak may be the oil pressure switch or the oil filter adapter. Can't swear to it, but I thought GM had the halfcase seal taken care of by 2000. Mine is dry.

Absolute dealer top dollar in the DC metroplex area for this car in excellent mechanical condition is $3560. That's for a perfect, inspected, emissions-compliant (federal law) car.

Top dollar off someone's front lawn with NO guarantees, in visual excellent condition, is $2635.

You got stung, and stung bad. www.kbb.com (http://www.kbb.com) .............. I'm not saying that Kelley Blue Book is the only used car pricing guide around - but they've been around longer than I have, so they must know something.

.............. basscatt's post ^^^ ............... Most car sellers on Craigslist fall into the category of "Beautiful Dreamer".

The picture of the engine compartment - that's why the Korner Kar Korral has a volume deal with a local shadetree detail shop ............ engine compartment renewal spray is cheap.

5300 is way too much for the car in its condition. I'd return it and get a different one. It needs alot of work (suspension and oil leaks are not cheap on these)
