1998 Cadillac DeVille OverHeating !!

It also leaks out all the antifreeze or water I've put in You should see my trunk I've got so many bottles of antifreeze and water it's crazy .

Thank you so much that's very useful but it turns on it just says that theft system problem may not restart and this morning was the first time it made me wait 3 minutes should I still try that ? White smoke tail pipes I'm sorry that's a little confusing to me could you explain a little more in that aspect of the question please ?

I was on YouTube this morning and one guy said his was doing the same thing the over heating thing and he Had to replace the overflow tank and on the theft system some people had to replace their key I believ they were saying I guess the key was messing with the small wires in the ignition they didn't shed too much light on that but I think that is what they were getting at .
