Sigh...I just got a 2000 Cadillac SLS about a week ago. I drove it about 6 miles on the e-way and the temp light started moving to the right...the display read "engine coolant temp hot idle engine a/c off" or something to that extent. I've taken it to several people and they say they can't find anything else wrong. I do not know what else to do now. I love how it drives but right now I can't even drive across town. Does anyone know what could make this temp go up and stay up like that? One of the mechanics even told me that it could be an airflow problem and if that's the case then I'm wasting my time? Awww man, I had thermostat replaced and had a flush & fill to no avail...kinda bummed right now because I love the car to pieces.

Sounds like the dreaded much discussed blown head gaskets, did you get the car for a great price?,
whats the mileage?.

I'm surprised THAT many people you took it to have no familiarity with the obvious problem with that motor. Time to get a block test.

I think I got a good deal...I paid 3 thousand and some change and it has 182,000 miles on it. I expected to get some work done but frustrated that I can't get good help around here...like wow. Thanks for reply I will consider having those checked.

Where are you located? There might be Northstar experts you can tow the car to.


There's a chance its something else, but I'd bet my life on it being head gaskets.
I'm in Mid-Michigan and you would think this area would have some experts around here considering we were "vehicle city" near Detroit who is the "motor city" smh...

gosh i khnow in Detroit every other mechanic you go to would know about these northstar issues on this engine


maybe this might be best to move it to the Northstar Technical Section of the forum i know it might get more atention there

how ever it does sound like the HG's are gone but there is that percentage that its something els

sounds almost like the shop you took it to did the t-stat and flushed the coolant system perhaps they knew the issue and figured they could make a few bucks of you at first before telling yout hat you have 4 grand worth of work to be done that way they don't loose your business i mean money they could robb you for before you say no to the other work

Someone saw you coming and bent you over. Did you buy from a dealer or private (not that it matters all that much)? If you got it from a dealer and it was VERY recent, you might go back and raise holy hell, but used car sales are "As Is".

not sure how other states are but i know in Ohio
you can have some auction to be taken and have a leg to stand on in court if it went that far if
they actualy tried to hide the problem from you in ohio thats not leagle and you can sew and win
not sure how other states are but i know for a fact in ohio
a dealer and a private party can not deliberately hide the issue with the vehicle being sold

they don;'t have to tell you about it but if leading you on by saying it is perfect nothing is wrong i with it or if you ask specific question before purchase they can try to avoid those answer but if they plane out come and say no then you have a leg to stand on

also there comes down to the point you have to prove they knew it was bad

but no matter what state if it where me id be going to small claims court sewing them
good chance you may win something

Sadly :yeah:

Best of luck to you my friend. Those HG repairs can be pricey. :hide:

Greetings and salutations.

The good news: Sunchips are my favorite chips.

The bad news: Sounds like you got a bum deal, which is too bad and a horrible way to get associated with the Cadillac brand. Whatever you do - DON'T let the engine overheat. Blown head gaskets can be pricey, but are salvageable.

All the best in your situation and hope it pans out for you.

Sadly, someone without ethics sold you a car rather than repair it.
Your purchase price of $3k is about the same amount it will cost you to timesert or stud
your block.
The car was worth $1k tops with a HG issue and high mileage.

Well, the truth is the HG problem is not that much common that we think! And that is why 90% of mechanics out there have never ever heard about it... We are in a forum and people come here to discuss their problems. That is why we hear a lot about it in this forum, but there are millions of flawless N* engines pushing these luxury car forward!

About the thread, yes, 3000$ for a 180k miles SLS is too much even if the HGs are good!

Nope! Cheek spreaders should have been a red flag! :lildevil: On a serious note, you should have come to this forum BEFORE buying it. It is a good car with a very troublesome motor. :yup:

What planet are you from again? I attend many car auctions. Believe me, EVERYONE at said auctions is well aware of the HG issue and avoid anything with a N* unless it goes stupid cheap! :bigroll:
