An overheating car can cause the head gasket to blow. When the combustion chamber gets penetrated with coolant, the engine loses its equilibrium. The ability to keep heat levels from rising as the car moves faster along roads and freeways. This causes the engine to overheat unless the coolant is refilled on a constant basis. After the engine is shut off, coolant that is in the cylinder can leak into the engine oil. The oil will often assume a milky appearance that can usually be identified with an inspection.
When the engine runs, white smoke will form from whatever is left of the coolant inside the combustion chamber. The smoke in question is easiest to identify on warm days, when it can often be seen blowing from the exhaust pipes as the car sits warm and idling. Symptoms such as these can be identified by certain smells. A sweet smell is usually indicative of a head gasket problem.
Notice the exhaust
Exhaust gases from the combustion chamber could enter the cooling system, where it will circulate and pass to the radiator. The easiest place to spot evidence of this is in the cooling tank, which may contain bubbles as a result of pressurization. The cooling system remains pressurized for as long as the engine is warm. The radiator cap should never be removed while the engine is idling or has just recently been shut off.
If the head gasket has blown, refrain from driving your car much, if at all, until the problem is rectified. The components that connect to the gasket can get warped or irreparably damaged from the temperature extremes and fluid leaks that head gasket problems can cause, all of which could result in huge repair bills.
