Question about 2007 Lincoln MKZ
Your cooling system is half full of air it sounds like. With the engine cool start it up and remove the radiator cap leave it running. It will take probably 10 minutes for the thermostat to get hot enough to open up, when it does you will see the fluid in the radiator start to move and then I'll bet the level will drop where you can't hardly see any fluid. Fill your radiator with coolant and water, or just water better to use coolant as it won't build up as much with minerals from the water. It's best if you can pre-fill some gallon jugs of water so that it is warmer then straight out of the hose. Anyway after fluid drops fill up radiator with fluid and repeat until fluid level no longer drops. Then fill the overflow tank to the appropriate level. Let me know if you need more assistance by commenting back to this post. Good luck and I hope this fixes your problem.

I have the same exact car that had the same exact problem! My car kept getting an air pocket because the cap on the overflow tank was old and couldn't withstand the appropriate amount of pressure. I recommend checking that as well with this car. It took three mechanics in three different garages and about $1800 to figure it out and repair it correctly! I really hope this helps someone else who owns this same car!!

That doesn't sound good. There could be other things wrong, but I would suspect a blown head gasket. you will need to check the top of the radiator fluid for oil floating in there. check for steam coming out the exhaust, and you could check the oil for water, but you should know something before you do that. Go to a radiator shop and for about $50, they will do a compression check and tell you exactly what cylinder it is and how much it will cost to fix. probably $2,000. It is a big job. Hope this helps.
