#2363 of 2635 Need Expert Advice on Comparing 2000 Deville and Eldorado
Aug 20, 2007 (9:16 am)
Looking for some sage advice from experienced Cadillac type. Decided to buy a used Cadillac, wanted a Northstar engine. Decided on 2000 because they made improvements to the motor. Regular gas, redesign etc. Assuming it makes sense to get 2000 vs. earlier due to motor advances?
Can get equally good deal on a Deville DTC or Eldorado ETC. I prefer the classic body style of the Eldorado and would have to get use to the look of the new style Deville. Like the taillights on the Deville but the front end is different. Also, age 46, only me and the wife and a small dog, no kids.
Is it just a question of looks and desired style or is the redesigned body on the Deville model for 2000 significant enough that I would notice the difference in quality, ride, or performance?
Bottom line is I could learn to like the looks of the Deville body style if the drive experience was significantly different over the traditional chassis on the Eldorado. I prefer the looks of the Eldorado but do not want to give up too much for that style preference. Hence lies the dilemma.
Thanks in Advance.

Hey, you are asking questions that only your personal preference can answer.
Go test drive both and decide.
One thing about 2000 model Northstar - Crank sensors. There are two of them. And many of them fail. Failure will cause a total engine stop, and it could be at speed. If your car does just die suddenly, this is probably the problem, and I would repair it quickly before you have a flameout at 75mph in the left lane of a busy highway.

Thanks, sounds like what I have heard so far. But the dealer and the independent shop hasn't mentioned pulling the engine too. Hope not, sounds like a way to start a never ending chain of failures. Can't pay that bill!
Curious question.. The other guy that was talking about a 2000 ,,, you said something about it cutting off with him...Does my 96 have the same thing that can do that??? Because it has been (as you say..Flamed out!) At different times. mostly while slowing or accelerating, BUT.. has done it sitting still in driveway?? Thought it could be a lose wire( had a turn signal module fixed not long before it started).... or thought maybe the Computor...So am I on the wrong track there? thanks rebeccat

Well, from what I've read, the 2000 and maybe up into the 2001 models seemed to have an especially bad batch of crank sensors, with lots of failures.
But, I am pretty sure earlier models of Northstars also had 2 crank sensors. 1995 and earlier had a totally different 'computer' system (ODBC I), and I'm not sure about these.
Your 1996 is an ODBC II, and probably has 2.
If a Northstar just 'drops dead', a crank sensor problem would be the first thing I would consider. Especially if NO error code was set. It seems these things shut stuff down so fast, it does not even get to set an error code.
They are not especially expensive, and not too much problem to reach. They are both just above the oil filter adapter. I think oil needs drained, filter and adapter removed, and there they are.

Except for the shift and speed sensor solonids, Northstar transmissions are relatively bulletproof.

Since they didnt give me the book when I purchased the car -2002 DHS Deville , I dont know what this means.
The oil in the car was changed at 51,000 miles.Not due for another change until 54,000 miles.
Car now has 52,000 miles on it. And the light is coming on saying: "Oil Life 87 % "
I checked the oil and the stick is still at full mark.

What light is coming on
If your oil indicator is coming on when the engine is running, that may mean that the oil pressure is low.
The oil life message is displayed in the driver information center. This indicates how much life is left, and you have used about 1/8 of the total life, so you can go about 6-7,000 more miles. However, if the oil pressure is low, your engine is probably near death.

The message is a constant on in the information center from the moment I turn the car on.
So I hope it is only informing me of the life of the oil..although my other caddy had nothing like that. Some posts here have spoken of the need to top up oil before it's time for a change and I was wondering if that's what it meant...a need to top up...but the stick was still on full.
How would you find out if the oil pressure is still good? what would I ask the mechanic to do?
Thanks for the help.

You shouldn't need to add any oil if it is at the proper level on the dipstick. The 87% is calculated by the car diagnostics to tell you how much life you should have left before you need to change the oil. You should be able to clear this message by going into you DIC buttons and then it shouldn't come back until you want it to. Try a search on the net for something like mygm.com or mycadillac.com and you should be able to pull up an online manual. If you bought the car new go back to the dealer if you bought it from and individual you could probably buy one from Ebay. Good luck.

You need the Owner's Manual for your car. They are not very expensive. You can probably find one on eBay, or you can order a new one at www.helminc.com This company is the publisher/printer for owner and service manuals for most of the auto makers.
You don't have a problem. The main thing is, you need to get your dash to display something other than your oil usage percent. You need to have an owner's manual to read so you will know how to do this. And there is all kind of other stuff in the owner's manual. When you get it, you should read it end to end at least once.
Many, many, many of the questions asked on forums like this can be answered by reading a vehicle's owner manual.
