Cylinder Heads
What Is a Cylinder Head and Why Does It Matter?
The cylinder head is one of the most critical components of any internal combustion engine. Sitting on top of the engine block, it seals the cylinder's working space and ensures combustion, cooling, and lubrication all function correctly. EuroFrance stocks new cylinder heads for popular French brands such as Renault, Peugeot, and Citroën, as well as for Nissan, Dacia, Ford, Volkswagen, and more.

How Is an Engine Head Constructed?
Inside the cylinder head you will find oil channels that transport engine oil, as well as coolant passages that help regulate operating temperature. In many modern engines - including popular models like the Clio 2, Clio 3, Kangoo, and Megane 2 - the camshaft is housed within the head itself. The construction must be precise to maintain a tight seal and ensure every engine sub-system operates reliably.
What Role Does the Head Play in the Engine?
The engine head is where the fuel-air mixture is compressed and ignited, generating the energy that drives the vehicle. It also contributes to structural rigidity, which improves stability and reduces noise. Cooling and oil channels run through the head to keep the power unit at safe operating temperatures, while exhaust ports allow spent gases to exit the combustion chamber.
What to Consider When Replacing a Cylinder Head
Correct torque and tightening sequence are essential when fitting a new head. Always use a torque wrench and begin with the central bolts, working outward in a cross pattern. This ensures even gasket compression and protects the engine block from warping. The replacement should be carried out on a cold engine. For cast-iron blocks, it is advisable to retighten the bolts after the first heat cycle.
Choosing the Right Engine Head
When shopping for a replacement, make sure you match the head to your vehicle's exact make, model, and engine code. You can filter our catalogue by brand, model, manufacturer, and condition to narrow down the options quickly. If you are unsure, our team can verify fitment using your vehicle's VIN or the OE part number stamped on the original component.
