Cylinder Head

The Car’s Cylinder Head: Function

The cylinder head, also known as the head or block head, is one of the most important components in a car’s operation. It is located at the top of the engine block and is responsible for sealing the combustion chambers, allowing air, fuel, and exhaust gases to flow properly.

Proper maintenance of the cylinder head is key to avoiding costly failures and ensuring the engine’s lifespan. Below, we explain its function, the most common problems, and the best practices to take care of it.

Function of the Cylinder Head in the Engine

The cylinder head performs several critical functions in engine operation:

• Houses the valves and camshaft
  It contains the intake and exhaust valves, which control the entry of air and fuel and the exit of burnt gases.
• Seals the combustion chambers
  It works together with the head gasket to prevent leaks of compression, oil, and coolant.
• Controls gas flow
  It ensures proper gas circulation, maintaining engine efficiency and preventing power loss.
• Regulates temperature
  In many cases, it integrates coolant passages that help dissipate the heat generated during combustion.

Common Problems in the Cylinder Head

The cylinder head is exposed to high temperatures and internal pressures, which can cause failures if not properly maintained. The most common issues include:

• Damaged head gasket → Causes mixing of oil and coolant, overheating, and loss of compression.
• Cracks or warping → Caused by prolonged overheating or poor lubrication.
• Carbon buildup → Excess residue in the valves and combustion chambers affects performance.
• Oil or coolant leaks → When the sealing is no longer effective.

Ignoring these problems can lead to costly repairs or even the need to replace the entire engine.

How to Care for the Cylinder Head to Make It Last Longer

A well-maintained cylinder head can last hundreds of thousands of kilometers. Here are some key recommendations:

1. Monitor engine temperature
   Overheating is the cylinder head’s main enemy. Regularly check coolant levels and ensure the cooling system works properly.
2. Change oil and filters on time
   Clean, high-quality oil prevents premature wear of valves, the camshaft, and other internal components.
3. Use the correct coolant
   Don’t use plain water in the radiator. A proper coolant helps dissipate heat and prevents internal corrosion in the head.
4. Don’t push the engine when cold
   Avoid sudden acceleration before the engine reaches optimal temperature. This protects the sealing and internal parts.
5. Do preventive maintenance
   Periodically check the valves, head gasket, and cooling system at a trusted workshop.

Conclusion

The cylinder head is an essential component for the performance and durability of the engine. Proper care can save you from expensive repairs and extend your vehicle’s lifespan.

Remember: monitoring temperature, maintaining proper oil and coolant levels, and performing preventive maintenance are the keys to keeping the cylinder head in excellent condition.

If you notice unusual smoke, loss of power, or abnormal coolant consumption, visit a specialized workshop immediately. Detecting problems early is the best way to protect your engine and your investment.
