Etc and overheating on 2003 Lincoln ls 3.9 v8

I would key on the overheating first. Make sure you have properly blead all the air out of the cooling system. Air in the system will cause it to overheat. If you are sure all the air is out then inspect coolant cap. If gasket appears warn or extremely loose then replace with proper psi cap for your car. Bad cap can cause overheating. How hot did it get when the res broke? If it got overheated might have a head gasket issue but let's hope not. If in USA go to auto zone and have the codes read. What are the code numbers? Post them back on here this will give us clues to the etc limp mode problems. Possibly a bad coil on plug assembly.

Usually the degas bottle slowly rots and will not show signs of leakage, but if it's yellowed, replace it, then put a purge kit on the heater hose line, and purge from there with the bleeder open until all the air hisses out of it and you have a steady dribble...make sure the level at the degas bottle (or as some would call, the recovery tank) is to factory spec...I went round and round with my 2003 LS v8 on the overheating until I did this, practically replacing everything over the course of a year, with no overheating problems since then...but purging from the heater hose will push the air out of the coolant system better than ANY Lincoln recommended process, and air in the system KILLS the plastic parts of any LS's cooling system. The pressure building usually causes cracks to form in the plastic components...

I'm in the same situation my car keep over heating after the transmission shop stopes it from over heating the first time

I.Have the same problem right . now. What ! choose. I.try doing this "the 3th's time.i. Have take. Off.the recovery tank. And it's. Still get. Over heat ing ?
