What Causes an Engine Block to Crack? Know the Signs and Prevention

A vehicle’s engine block houses the combustion chambers and other essential engine components. Made from durable metal, it endures heavy use. However, a crack in the engine block, though rare, is a serious issue that requires immediate attention. If you suspect a problem with your engine block in Ontario or anywhere in Canada, our team at Greasemonkey Inspectors is here to help.

Signs of a Cracked Engine Block

Recognizing the signs of a cracked engine block early can save you from significant repair costs. Here are the key indicators:

  • Overheating: Unusual temperature spikes in your engine.
  • Engine Smoke: Smoke emitting from your engine.
  • Poor Performance: Noticeable drop in engine performance.
  • Antifreeze and Oil Mixing: Coolant mixing with engine oil.

Driving with a cracked engine block is dangerous. Understanding the causes and preventive measures can help you avoid this issue.

Causes of a Cracked Engine Block

  1. Low Coolant: Excessive heat due to insufficient coolant can cause the engine block to crack. Coolant helps maintain safe engine temperatures.
  2. Failed Water Pump: The water pump circulates coolant through the engine block. A failed pump often leads to coolant leaks, whining noises, or steam from under the hood.
  3. Overworked Engine: Installing non-OEM turbochargers or superchargers and towing loads beyond your vehicle’s capacity can overstrain the engine.
  4. Extreme Elements: In cold regions like Ontario and Canada, frozen coolant can exert pressure on the engine block walls, leading to cracks.

Routine maintenance is crucial for preventing a cracked engine block. At Greasemonkey Inspectors, we ensure your vehicle is in top condition by:

  • Maintaining Coolant Levels: Regularly checking and topping up coolant to prevent overheating.
  • Inspecting the Water Pump: Identifying leaks or failures early to avoid engine damage.
