Thirsty Car with the coolant?

Question

2000 Ford Contour SE 4 cylinder. I fill up the coolant tank with coolant/Antifreeze and sometimes with water, I have to keep filling it up almost every day sometimes it last one day sometimes 3... I dont see any leaks, and mechanic couldn't figure it out, he says it could be that it evaporizes... any idea what can be the problem?

Answer 1

Head Gasket blown.

You won`t be able to see any leaks as the engine will be burning the water.

You can detect the signs of a blown Gasket as the car will be blowing out white smoke (steam) from the back end, not just on cold start.

Answer 2

Head Gasket Blown, burning up throw the exhaust!
