Detailed Product Information

Victor Reinz 14-32308-01 is specified for cylinder head installation work where original head bolts should not be reused. Torque-to-yield fasteners are engineered to stretch during tightening, which helps create the clamping load needed for a secure head gasket seal. Once stretched, they can lose their ability to hold proper load, so replacement is the correct service practice during head removal and reassembly. This part cross-references MAHLE GS33581 for the same application. Fits 2002-2005 BMW 745i, 2002-2005 BMW 745Li, 2004-2005 BMW 645Ci, 2004-2006 BMW 545i, 2004-2006 BMW X5, 2006-2010 BMW 550i, 2006-2010 BMW 650i, and 2007-2010 BMW X5, including N62 B48 B Engine applications.

Common Repair Uses

• Replacing stretched head bolts during BMW cylinder head service
• Restoring head gasket sealing after overheating or gasket failure

Installation Notes

Follow the factory tightening sequence, torque stages, and angle specifications for the specific BMW engine. Inspect the cylinder head and block mating surfaces before assembly, and replace head bolts any time the cylinder head is removed on engines that use torque-to-yield fasteners. Verify engine code and model-year fitment before installation.
