How to Know If an Engine Block Is Cracked


Look for leaking engine coolant, most notably as it drains out the bottom of a car. This is a telltale sign of a cracked engine block, and in time, can cause an engine to overheat.


Check the dashboard and check gauges. If any of the dashboard lights come on, whether related to oil or coolant, this could signify a cracked engine block. Also, if the temperature gauge begins to signal overheating, this could mean engine coolant is leaking, which is a potential sign of a cracked engine block.


Look for extra smoke coming out of an automobile's exhaust pipe. While a certain amount is common, extra amounts--long trails coming out of an exhaust pipe--could signify a cracked engine block.


Check to see if a car radiator's mixture of engine coolant and water is optimal. This should be half water, half antifreeze, in most cases (it will often be indicated on an antifreeze bottle's instructions). If the mixture is not proper, this can cause the mixture to freeze, which will crack the engine block.

Of all the cogs that keep an automobile running optimally on the road, none are more important than a car's engine. Unfortunately, a cracked engine block can cause performance troubles with a car, and in time, can cause an automobile to stop running altogether. Fortunately, there are ways to identify a crack in the engine block, which can help lead to repairs.
