I did everything on the car and the reality is this car line or engine better said (north star) has had the same problems, and after replacing everything on it, the problem is that the heads became defective and they get cracked or warped. Even when they take it out and check them, they might look great, but in reality they are cracked from the inner tube.
This crack inside the head is the real reason for overheating n* engine, and don't buy any sealer that promises to fix the problem; see the thing is that they use glass, copper, aluminum etc to block it, but the issue is that it is not water going to the engine or oil to the water, the problem is there is pressure escaping from a cylinder into the water. The smaller the crack the more it takes to overheat, but don't waste your time and money with these engines; one way or another you'll have to just replace the heads.

I have a 99 STS with about 103000 miles on it. I replaced the water pump about 4 months ago.
Prior to the car offically over heating I was smelling Anit freeze and was told that my radiator was cracked. I replaced the radiator and the car began to run hot again literally days after replacing the radiator. I was then told to replace the thermostat. 3 days later it ran hot AGAIN and was told the head gasket was blown. I love this car to death and really don't want to get rid of it. I am considering replacing the engine altogether. Is the engine on a 2002 Cadillac interchangeable w/the 99?
How do the heads on these Northstars fail if the engine never has an overheating episode? Are the heads that weak that they will just give at anytime?
I am hoping to get a response from the person who wrote (or someone else who has done this):
"As far as the oil goes. You probably have a drip leak and the oil pan needs to be replaced... I ran into this problem myself on my 99 STS. From what I understand, it is very common. I bought the gasket for $12 from Autozone and put it on myself. Don't let some mechanic tell you it is a major ordeal because it is not. You will need to use a 3/8 ratchet and extension if you do it yourself."
It looks like I also need to replace the oil pan gasket on my 99 STS, but I am having a couple problems with it. First, there is an odd bolt that lies right next to the transmission housing and looks like it runs through the oil pan and will need to be removed as well (I used a 10 mm instead of the 3/8 for most of the bolts, but this bolt appears to be about 13mm or 1/2 inch). Did you not need to remove this bolt? If you did remove, how did you do so? I cannot get a socket head fully around it because it hits the transmission housing. Second, it looks like there is not enough room to drop the oil pan without removing the exhaust. Were you able to squeeze it out?
Car shaking at high speeds could be tires need balancing and rotation...
Or brakes need machining.

99 ETC.
I have a 1999 Cadillac STS, and it overheats only when I drive it. I replaced the waterpump, thermostat and cooling fan relays. The fans turn on right. I drive it and I hear a water noise like behind the dashboard. What could it be?
I am having the same problem (overheating) and hear the same noise. Any help would be much appreciated.
I have 99 STS. The warning lights - traction control and ABS come on some times then go off and come on again. Seems like a little gremlin in there wants to mess with my mind.
Can anyone help??
I have a 99 SLS. Only problems have been the fuel pressure regulator for the fuel injection, at the same time a leaky water pump was found. Other that that it's a great car - especially on the interstate, it gets over 28 mpg @ 75 mph. Around town average 18-19. Better than my girlfriends Accord!
Just like a Corvette, parts and labor are pricey at a dealership, that's why it's called a Cadillac/Corvette Tax (LOL).
The SLS doesn't like to be driven hard, when I first got it I almost went off the road sideways a few times. An AMG Benz it ain't.
There is the oil consumption thing to deal with. At first I went nutz looking for drips and leaks, checking the exhaust tips for oily residue, etc. it is, apparently normal for the N-star, just part of the expense of driving a Caddy. I do keep an extra qt. or 2 of oil in the trunk, just to keep them handy. Overall an enjoyable car, but expensive to operate.
Ciao, ya'll, Mark.
Our 99 sts cadillac stalls out when driving, sometimes when stopping for a light, sometimes when coming off the expressway it stalls out. Now it is not starting - either from sitting overnight or after driving and then sitting for an hour or so.
Anyone having any problems like this?
We have taken it too many mechanics, changed battery & cables still doing it.
Would appreciate any help. Thanks.
I have a 99 STS with a ironic problem. When the key is on but not started everything works perfect, but when you start the car nothing electric works, my windows my locks and my music does not work; when I turn the car off and put the key back in the on position everything works perfect, I have no idea what it is, it just started happening one morning, if any one may have information please let me know ASAP, thank you.

The 2000 STS has survived 137,000 miles, and now the rear air shocks don't pump up even with no weight. They show a very low ride height. Has anyone experienced a similar problem, and if so would you share the repair necessary to bring back the quality ride height necessary to prevent the bottoming out effect

I have a 1999 Seville SLS. I have had it for about 2 & half years. I bought it with 58,000 miles and have put about 30,000 miles on it. Like some of the other comments, my Seville shuts down without any warning. Sometimes the shut down occurs at high speed and sometimes when I am just starting or stopping. It is also sometimes difficult to start. Has anyone found a solution to these issues?
My radiator just went after I was smelling anti freeze, so how hard is it for someone that has never touched a radiator before to change it?
Just sell the car as soon as you can, bad engine period.
