Crack Control

Why Does the Engine Block Crack?
A very large portion of engine block cracks occur due to heat or external factors. The most common causes of engine block cracks are;

• Engine block cracking due to heat
• Hot engine coming into contact with sudden cold liquids (Sudden Expansion)
• Engine Coolant Freezing and Expansion in the Engine Block in Winter Months,
• Thermostat Working Mode Problems
• Disruption of Water Circulation in the Engine Block Due to Circulation Pump Failure
• Displacement of Piston Rods and Bearings, Breakages
• Impacts Due to External Factors

Apart from these reasons, a few rare reasons can be listed. The first answer to the question of Why Does the Engine Block Crack? The most common cracks are cracks that occur due to the vehicle overheating and cracks due to the freezing of engine water in the engine during the winter months due to the lack of antifreeze in the engine coolant. As it is known, there are volume differences between the liquid, gaseous and solid states of water. When water freezes, it expands and exerts high pressure on the engine block by forcing the volume it is in. This pressure can be considered the most common cause of cracks on the block.

What Happens If the Engine Block Cracked?
What can happen depends on the crack in the part in question. Another variable that determines the effect it will have is the part of the engine block where the crack is. A crack on the outside only and a crack on the inside or upper valve section will have different effects on the operation of the vehicle. Therefore, each of the effects listed below may not be experienced in all vehicles with cracked blocks. The most common effects are:

• Engine Coolant Flows from the Crack and the Vehicle Can Be Dehydrated
• Engine Coolant Mixes with the Oil and Accelerates Internal Engine Wear
• It Can Cause Overheating Due to Antifreeze Deficiency and Engine Damage Due to Overheating
• It Causes Compressor Leaks
• The Vehicle Loses Traction
• Ignition Systems Such as Ignition Coils and Spark Plugs Cannot Work Regularly
• The Vehicle May Experience Misfiring or No-Work Problems Due to Moisture and Water Entering the Combustion Chambers
• Engine Oil Mixes with Vehicle Water and May Cause Parts Such as the Radiator and Circulation Pump to Fail.
• Water Dripping and Spraying from the Exhaust May Be Observed.

Apart from these, depending on variables such as the location and size of the crack, there may be other reasons that may affect engine operation.

If Engine Block Crack Is Not Noticed
Failure to notice the malfunction in question will cause other, more costly malfunctions to occur. For example, the effects such as the welding of rings and pistons due to the engine heat, bearing wrapping and internal engine wear due to the loss of oil properties can be seen. Therefore, in the event of any crack, the vehicle should not be moved, should not be operated and should be transported to the service with the help and advice of a master. Otherwise, it seems highly probable that you will experience different malfunctions.
