I am currently looking at purchasing my first car. I have the opportunity to purchase a 1988 Cadillac Sedan De ville 4.5L. I was wondering what the "special" liquid that I have to combine with the anti-freeze, is called. If anyone can help me out, I'd appreciate it greatly if anyone is able to get back to me.

I own a 1988 Cadillac Sedan Deville. White on red, and it is one of the best cars I have owned yet. It has been very good to my wife and I.
I have few hidden rust spots mostly in the front door jams, but everything else is cherry. The leather is still great, and as far as I know, everything is running properly (I hope so).
I don't think after owning this Cadillac as my first one, that I will never drive anything else but Cadillac. Go Detriot!

I also just bought a 88' De Ville. It's the best car I've had so far, the only problem with it is the passenger window.
The car has a powerful V8 5.0 liter engine. It's in very good shape. I bought it for $850 with 122,000 miles, and two days later I got an offer for $3,500. But in those two days, I fell in love with it, and I wouldn't sell it for anything. I know I would regret it if I ever see saw again and I'm in a piece of crap like a civic or some wheel-barrow like that.
Bottom line - I love my DeVille and I'm pretty sure I'll be a caddy man for the rest of my life.

I've owned a 1988 blue Cadillac Sedan DeVille since 1993. I am totally in love with this car. I've had pretty much everything replaced including new transmission, except the engine and the fuel pump.
It's not my everyday car, so I dust it off every couple months and drive it. A few weeks ago I did just that, filled the tank ($46 later) and it was running fine. I made a stop at the grocery store and when I tried starting it, it wouldn't. Called the towing company and they couldn't get it to jump, so I had it towed back to my home.
A couple days later I attempted to start it and it started right up. About a week later, I tried to start it and it was dead.
I planned to donate the car, but when I told the organization about the dilemma, they decided not to take it. I'm keeping the car. I contacted a Cadillac dealer and had it towed there. It's still there - they put it a new battery, but as of yesterday, they couldn't figure out why it wasn't turning over. My mechanic thought it might be the fuel pump. Has anyone had a similar situation? I appreciate any comment you may have.

I just picked up a 88 DeVille with 77,000, on it, 1 owner perfect shape with all the records and maintenence papers. It was garage kept and pampered for its whole life. It has a 4.5, pearl gray, blue leather and all transferable warranties for paint and rust. My friends said that the 4.5 alluminum engine is a possible problem. What is the consensus on it? I paid $2000 for it.

The Gas/AC display on my 1988 DeVille randomly went out when I turned on the car, and I did not know if I changed a setting by accident/blew a fuse/or something else happen to it. I checked the fuses underneath the left side of the steering wheel, and none of them were blown. Any suggestions would be helpful. All other lights and gauges work.

I am currently driving a 1988 Cadillac Coupe De ville, chocolate metal flake exterior with cream valor interior. It is in very good condition, with 59,000 original miles. The problem I have is it leaks oil, and literally guzzles gas. It is a very expensive car to drive. Any suggestions?

I read your comment you made about the 1988 Cadillac DeVille A/C problems, and I have a 1988 Cadillac DeVille that is having the same problems. And I have done all of the same things that you have done, and it still switches to economy. I was wondering did you ever figure out the problem and how to fix it? If you could tell me I would really appreciate it. Just email me at email@example.com

I had the same problem. My mechanic found the cause. It was one of two temperature sensors. He checked with Cadillac and all his suppliers. Nobody had them, and they did not make them any more. He showed me what to look for and what to cut off on an old Caddy at the junk yard. I found a 1989 at a junk yard 9 miles from my house. It's been three years and cost me $20.00. It works great. p.s. Three other good mechanics tried their luck.

During the hot months my A/C works OK as long as the temp in the am is warm; at least 10+ degrees on the auto setting. In the winter here in Texas it can be cold in the am and warm in the pm. I have to turn the A/C off each time. If I want the A/C, not the heater to come on, I disconnect the battery and then I can use the A/C. But once the heater comes on, I can't use the A/C.
