coolant flush/change clarification

[MichelleGill]

This is the most serious, costly, and complex problem to solve. If the car overheats, there is foam in the expansion tank, there are problems in the heater operation, and there is white smoke coming from the exhaust pipe - it is most likely the antifreeze leak into the cylinders. But in practice, not all symptoms listed above may be present. Two more signs of antifreeze leaking into the engine are white specks on the spark plugs and whitish emulsion on the engine oil dipstick. Causes of the problem include a cylinder-head gasket (CGB) failure, warping of the cylinder head itself, a crack in the cylinder head, or severe corrosion of the cylinder head.
