2000 Daewoo Nubira Repair Question
2000 Daewoo Nubira Coolant is boiling and gushes all out of
The only way to add coolant to this car is through the expansion tank.
So I add the correct amount of 50/50 and after minutes of driving it starts boiling in the expansion tank and it gushes out of the tightly closed cap.
There appears to be no leaks, crack, or holes in the tank or hoses.
I've let my car cool down and filled it back up with coolant, drove it and it happens again and again.
The temperature reads normal when driving the car, just sits at the middle, never higher.
I've read all around and everyone says it could be a bad Thermostat, Broken Water Pump, or a Clogged Radiator.
Everyone also suggests to get it pressure tested.
I just bought this car, and it runs perfect, the fans turn on, and the a/c is ice cold. The previous owner had just gotten the heads done.
How can I make sure the heads aren't blown. What do I look for, and what can prove that the heads and engine is just fine.
I checked my oil and it doesn't look like a milkshake, its dark and normal looking.
When the coolant boils, it gushes all out of the reservoir tank and empties all out. I also noticed very little steam coming from the place where you check your oil.
Did I get ripped off ?
Or is this an easy fix ?
You can get a head check done, this will check for any exhaust gasses in the cooling system, a sure sign of a head problem, but i would also recommend that the thermostat & radiator be inspected as well.

Today I removed the thermostat, and put put it back together without the thermostat to see if that was the problem, but still the same exact thing.
My radiator does not have anywhere to apply coolant to, you can only apply it to the expansion tank.
The correct coolant is the 50/50.
I drained it and added the 50/50.
I did realize that the CAP in the expansion tank is broken.
Its a Pressure Cap and the little spring thing is sideways and broken.
That might be the problem.
I will replace the cap tomarrow and try the same thing again.
This is the problem, I drive the car 10-15 minutes with the fans on and blowing the right direction, and everything is fine and smooth, the Temperature meter never passes the halfway mark.
But once I shut down the car, the coolant starts boiling and steaming in the expansion tank and it gushes all out of the tightly closed cap.
Now that I realized that the caps pressure thing is broken, hopefully that was the problem, but I'm skeptical it is......
Thanks and I will update.
