MAHLE GS34006 Engine Cylinder Head Bolt Set for 3.0L EcoDiesel

The MAHLE GS34006 Engine Cylinder Head Bolt Set is an OE-quality fastener kit engineered for complete cylinder head replacement on the 3.0L EcoDiesel V6 engine. As a global Original Equipment supplier, MAHLE designs these components to the same standards used by vehicle manufacturers, ensuring a precise, factory-correct fit and function.

These are torque-to-yield (TTY) fasteners, which means they are designed for single use only and must be replaced any time the cylinder head is removed. TTY bolts stretch to a specific tension during the torque sequence, delivering consistent clamping force across the entire head gasket surface to prevent combustion gas, coolant, and oil passage leaks.

Key Features:

• OE-grade torque-to-yield (TTY) cylinder head bolts
• Engineered for consistent stretch and precise torque retention
• Delivers proper clamping force to ensure reliable head gasket sealing
• Complete set includes all bolts required for one cylinder head installation
• Must not be reused — always install new TTY bolts after head removal
• Packaged in a shrink-wrapped tray for easy parts verification before opening
• Backed by MAHLE's trusted OEM heritage and quality standards

For best results, follow the OEM torque-angle procedure specified for the 3.0L EcoDiesel engine. This bolt set is recommended for use alongside a new MAHLE head gasket to ensure a complete, properly sealed cylinder head repair. Note: This set covers one cylinder head only — order two sets for a complete both-side installation.
