OEM 0204C1 Cylinder Head Bolts
The OEM 0204C1 Cylinder Head Bolts are specially engineered for Peugeot and Citroën engines, providing a secure and high-torque clamping solution for the cylinder head to the engine block. These bolts are essential for maintaining engine sealing integrity, ensuring optimal compression and preventing oil or coolant leakage during high-performance operation.
Key Features
Direct OEM Replacement: Matches OEM part number 0204C1, ensuring perfect fit and function for Peugeot/Citroën applications.
Heat-Treated Carbon Steel Construction: Provides high tensile strength and resistance to elongation under torque.
Precision Engineered Threads: Ensures accurate torque application and long-term cylinder head sealing.
Corrosion-Resistant Coating: Enhanced longevity even in high-humidity or high-temperature environments.
Essential for Engine Reassembly: Ideal for head gasket replacements and complete engine rebuilds.
Why Cylinder Head Bolts Matter
Cylinder head bolts are critical components that ensure the head gasket remains tightly sealed between the engine block and the cylinder head. Failure to use the correct head bolts during reassembly can lead to:
- Head gasket failure
- Coolant or oil leaks
- Loss of compression
- Engine misfire or overheating
The OEM 0204C1 bolts are torque-to-yield (TTY), meaning they are designed to stretch slightly under load for consistent pressure and reliable sealing — always replace old bolts with new ones during head gasket service.
Installation Tips
- Always follow manufacturer torque and angle specs
- Clean bolt holes and apply light oil to threads if specified
- Do not reuse old TTY head bolts – replace with new 0204C1
- Tighten in the correct sequence as per service manual
- Use a calibrated torque wrench for best results
We recommend installation by a qualified technician to ensure optimal sealing and engine safety.
