well when it starts to bubble out the bottle, how high is the temp
u may have to leave the cap off and let run for a bit may be an air lock trying to get out
otherwise its sucking in air from somewhere, run it let it bubble out for a bit but dont let it over heat.!!!!
so keep an close eye on the temperature

 

great news finally solved the issue... the purge line was clogged...... Thanks for all you help..

NEW issue... the engine flashed... read that there is a random misfire... so i googled and found i should changed the coil pack.... however i can i tell which cylinder is misfiring... or should i just replace the front and back. Your thoughts.

 

car gets warm, fans never run?

 

also the fans dont come on when a/c is on full

 

These are the basic things which always responsible for overheating your car's engine, which are mentioned in above posts, if you check these things and every part is fine then you need to get checked your car by some mechanic, because this can lead you some worst situation..

 

I have a 2000 deVille dts, I have spent a lot of time on and money. I have flushed everything out replaced hoses, thermostat, radiator, water pump. having difficult time bleeding because she wants to run hot on me. everything is put together right. The fans are working. How in the heck do you bleed all the air pockets out. I let it run for a while coolant level shoots up in the tank and bubbles up. When I let it cool off the coolant tank is bone dry. Am I doing something wrong here?
