1997 Cadillac DeVille Sedan de Ville from North America - Comments

I own 1997 Cadillac Deville that has started to over heat. I drive a mile and have to stop the car and let it cool down. I've replaced the ECT sensor and flushed the radiator, changed the thermostat and it's still over heating. It has great power and has needed next to no repairs until this problem started the other day... any advice for this dummy that bought a GM product.

We bought our 1997 Cadillac Deville in February of 2009. When we test drove it, it drove OK, nothing wrong with the car at the time. Bought the car that same day.

A month later, the check coolant level message displayed on the dash and we assumed that the coolant was indeed low. Well we waited too late on that because one day, the coolant tank must have ran out of fluid and the car started smoking. Engine temp got up to 250 degrees. Turned out that I had to replace the coolant tank the first week of April. That cost $233. That included a new tank, new thermostat and radiator work.

Then at random times, the oil light would flash saying to put more oil in it, but it didn't flash all the time. Checked oil, but oil was fine at the time so didn't do anything about it.

A couple of times, I've had the Battery No Charge message pop up when you started the car up for the first time that day, and it would stay there for like a couple of minutes.

About a couple weeks ago, the oil light started to flash almost every time we went somewhere when the car was warmed up good. Today, it was flashing, and not only that, the service engine light came on. I'm now assuming that the oil is low enough to where it needs maybe a quart or two of oil in it. Plan to put that in and see if it fixes both the flashing oil light and the service engine soon light. The oil life is at 44% yet.

I am now beginning to regret buying this car. I am the third owner of the vehicle and the previous owner stated that he had all sorts of things done such as digital cluster redone, new starter, fuel pump, A/C compressor. I'm beginning to regret buying this car now. It has about 141,000 miles and we paid 3000 for it from a private owner. There's my review on the car.

Own a 1997 Cadillac DeVille and the instrument panel has just gone black. Had mechanic check and was told not a fuse, will need panel removed, sent out to be recalibrated or replaced with rebuilt instrument panel @ approximate $600. Does this sound reasonable? How do I make sure it isn't "just a fuse" needing replacing? Help please.

Feb 2010.

Owner of a 1997 Cadillac that's of sentimental value. Needs a engine. I am willing to invest in it without regret.

I'm thinking emotionally and don't want to get ripped off with the engine.

Does anyone know of an honest business to either have the engine rebuilt? Or know of where I can purchase a rebuilt engine that will have a life expectancy of at least five years or more?

96 Cadi STS: Does anyone know how to disconnect the factory phone system? I disconnected one ground I found and see it runs off the fuse with other accessories the vehicle routinely uses. I can hear it hissing through the speakers when the car is off, and my cell signal develops interference, which is extremely annoying. Any Ideas?

2nd problem: I have the typical Northstar issues I guess. The most concerning right now is the unburned fuel smell, which is evident when traveling behind the vehicle when it is under acceleration. Puts out some smoke under WOT. I am a clean freak, and notice between cleanings the chrome tip exhausts are coated with black soot. I have changed only plugs and wires so far. Next will be the MAP, and clean the throttle body due to the rough idle. Any good ideas to get rid of that exhaust smell, or what could be causing it, would be greatly appreciated.

97 Cadillac Deville 120k miles, these days some bad things happened:

1. Rattle (or creak) noise when I accelerate the car.

2. Coolant temp goes 255+ quickly and causes overheating.

These two things appeared at the same time. After I put enough coolant in, it's still overheating. I don't know what's wrong, can someone help me?

My 97 Cadillac has the same problem as above. After dealers flush the radiator, the car does not go overheating again. Hope that will help.

I have a 98 Deville with 130.000 on it. It does use about 1 or 2 quarts about every 1500 miles, temp runs between 208 and 217, but other than that, it runs good. It is a very nice car. I only run Valvoline.

I have read a lot about this car. It is hard to find a good mechanic in Akron.

I would buy a Cadillac again. With all the problems with the Northstar, GM should held accountable.
