Setup, Compatibility & Care
Compatibility Verification:
Before purchasing, it is crucial to verify that this bolt set is compatible with your specific vehicle. Check the part number (431.440) against your vehicle's make, model, year, and engine specifications. Cross-reference with your vehicle's OEM part numbers (e.g., CITROËN: 0204.C4, PEUGEOT: 1698 228) if possible.
Installation:
- Ensure the cylinder head and engine block surfaces are clean and free of debris.
- Install the bolts in the specified sequence and torque them to the manufacturer's specifications using a calibrated torque wrench.
- Use the correct Torx bit (TX - E 14) for proper engagement and to avoid stripping the bolt head.
Care:
These are single-use, stretch-to-yield bolts in many applications. They should not be reused after removal. Inspect new bolts for any damage or defects before installation. No specific maintenance is required for the bolts themselves once installed, beyond standard engine upkeep.
