How to bleed the coolant system in a 2000 Deville on 2000 Cadillac DeVille

I have a 2000 Deville that I've changed the hoses, thermostat, water pump, and I think I have trapped air in the system. How do I remove it?

Once the thermostat is open your 2000 Cadillac DeVille should do a pretty good job of bleeding it self. If the thermostat does not open you can try the following. Fill the cooling system to the full mark on the overflow bottle. Run the engine until warm, about 240 degrees. If the cooling fans are on and blowing cold air then air is trapped and the thermostat is not open yet. In that case turn the engine off and wait about 30 minutes. This will allow the heat in the engine to spread evenly and allow the thermostat to open. Once the thermostat opens you can top off the coolant bottle to the correct level. When the cooling system is full and the thermostat is open the cooling fans will blow warm air when running.

I had that same problem And it actually blew up one of my hoses, and it use to bubble alot. Until i bought a stop leak in autozone. Its a plástico bottle containing alumitoonum. I cant remember the name of it cause i threw the bottle away. Its worth the try it worked for me its under 10$ too. Just pour it mixed. W/coolant dont have to drain. Cooling. System.
