Marine engine blocks will crack when the water in its passages freezes and subsequently expands. If the passages are full of water inside an engine, the frozen water needs somewhere to go sotheoretically it makes room by cracking the block, hence making it bigger. If an engine was subjected to a constant 32 degrees over long enough time to freeze entirely that would be enough. However, the manufacturers install "freeze plugs" in key spots so they give before the block. This buys some time. A few cold nights wont crack a block, but winterize the engine with antifreeze before the long cold winter sets in.
It should not
Yes
Are you talking about a crack in the engine block? Sorry, it's not repairable.
yes
no
If ice forms anywhere in the engine, it can crack the block.
crack the engine block and oil mixes with water or antifreeze.
Most definitely.
Lack of anti-freeze in sub-freezing temperatures. The water in the block freezes and expands.
Antifreeze helps by not allowing the coolant to freeze and possibly crack the water passages of the block.
A cracked block or a leak in the head gasket of the 1995 Impala SS can be caused by overheating the motor or even by drastic temperature changes. For example, adding cold water to the motor when an engine is hot can cause the block to crack. Gaskets sometimes leak when worn or when exposed to extreme temperatures.Ê
The repair is most likely more money than the car is worth, you need a new engine block.
