The Febi Bilstein 40838 Engine Cover Fastening Element is designed for automotive technicians and DIY enthusiasts who need a reliable, OE-quality replacement for damaged or missing engine cover bolts. This component ensures your engine bay covers remain securely fastened, preventing vibration and rattling noises caused by loose hardware. The primary caveat is that, while engineered to high standards, you must cross-reference your specific vehicle's year, make, and model requirements to confirm that these exact dimensions align with your engine assembly before installation.

No. Compatibility is based on thread size (M6 x 1) and length requirements. Always verify your vehicle’s specific part number compatibility.
The product information specifies the fastening element itself. Please check the included package contents or your vehicle manual if a specialized washer is required.
You will need a 10 mm spanner, socket, or wrench.
Yes, provided the threads remain intact and the bolt head is not rounded or damaged during removal.
The thread pitch is M6 x 1.
Always cross-reference the 40838 part number against your vehicle's specific service manual or OEM parts catalog.
Back the bolt out and check for debris or damaged threads in the engine mounting point. Never force the bolt, as this may strip the hole.
Verify if the engine cover requires a rubber grommet or vibration-dampening washer which may have been lost or degraded.
Ensure the 10 mm socket or wrench is fully seated on the bolt head before applying torque. Do not use an incorrectly sized tool.
Before installation, ensure the engine is cool to the touch to prevent burn hazards and to ensure thread engagement is not compromised by thermal expansion.
To ensure longevity, periodically inspect the bolt during your regular service interval. If you live in an area with high salt exposure or extreme humidity, consider applying a small amount of anti-seize lubricant to the threads to prevent future corrosion.
