What Causes a Cracked Cylinder Head?


Failed Water Pump


If the water pump fails, coolant won’t be able to circulate through the engine properly. The coolant in the radiator may be nice and cold, but the coolant surrounding the water jackets in the head and block will be extremely hot.

Without a pump, coolant will only be able to circulate via the natural convection process, which is much too slow to remove excess heat before the engine overheats.



Failed Thermostat


Combustion engines are most efficient when they are running at the operating temperature they were designed for.


An engine’s normal operating temperature is still plenty hot enough to scald you – typically around 190 to 210 degrees Fahrenheit (85 to 99 degrees Celsius). Running the engine below this temperature increases fuel consumption, emissions, and wear.


A thermostat blocks off coolant from the radiator until the coolant in the engine reaches the target temperature. Once the target temperature is reached, the thermostat opens to allow coolant at ambient temperature to enter the engine, cooling it until the thermostat is cold enough to close. The cycle continues as the engine runs.


If the thermostat is stuck open, your car will probably run pretty cold. This is because the coolant from the entire system is cycling through the radiator 100% of the time and rarely gets a chance to fully warm up.


If the thermostat is stuck closed, your engine will overheat pretty easily. The hot coolant has nowhere to go to cool off. In a pinch, some engines allow you to use the heater as a tiny radiator.


The effectiveness of this method depends on the size of the heater core and how the cooling system is routed.



A damaged cylinder head can be repaired. However, there is no point in fixing a head whose lifespan is over. It will still crack or warp almost immediately after. Cylinder head replacement offers a better solution. But then, not many people understand how to do it, or even when.
