well could be a thermostat or water pump or is it smoking out the tailpipe? if it is then you have a blown headgasket. the cooling ystem itself could be clogged and needs to be flushed. here are a number of reasons and i hope they help

SOURCE: my 1999 cadillac sts overheats alot i was told i

It hasn't been stated whether this is a Cadillac Seville STS, or an SLS. No matter, as they both use the 4.6 Liter, Dual Overhead Camshaft engine.

I would rate this as an 8, on a 1 to 10 scale. It would be a 10, if this Cadillac used wet sleeves. (Some Cadillac engines had a basic engine block, that had the water jackets open. The cylinders, are simply thick metal round tubes, with an O-ring at the bottom, and top. These set down in the block, and are held in place by the head.
There is a head gasket used also. When doing head work, or anything that involves removing the cylinder head, the wet sleeve cylinder, must NOT be disturbed from it's setting. If the cylinder is bumped, it can move, and the pattern the piston has made, will be disturbed. This means re-honing that cylinder. Lots of fun, these engines!)

Have you had experience with dual overhead camshaft engines? If yes, this is right up your alley. If not, be prepared for a small learning curve.

The engine must be removed. This is a transverse engine. The rear cylinder head May clear the firewall, it may not, if trying to remove it in the car. However, it is absolutely no fun trying to lay across the engine, and clean the gasket surfaces of the block!
This is just the tip of the iceberg, of bad things to come, when trying to replace the head in the car!

Just my advice.

SOURCE: 99 STS AC is blowing hot air

I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.

I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.

Good luck

I need the radio security code for a 1999 cadillac sts


You will need to contact Cadillac service at your local dealership. Give them the serial number on the radio. They can then pull the anti theft lock code from their companies archive. The serial number on the radio is typically tied to a VIN, but since you bought just the part, they can't search that way. Hope that helps.

How to reset the check engine light on a 2005 Cadillac STS V8?


If the check engine light is on, there is a problem that the computer has detected and it needs to be fixed first. Once the proper repair(s) have been made you can use a code reader that has the ability to "reset" the light. You could also just disconnect the battery for 15 minutes. If the problem hasen't been fixed the light will come back on.
