Engine Cylinder Head Bolt Set for Mercedes-Benz

Victor Reinz 14-32031-03 is an engine cylinder head bolt set for late-model Mercedes-Benz applications that use torque-to-yield head bolts. When servicing the cylinder head, replacing these bolts is the correct approach because TTY fasteners stretch during tightening and are not meant to be reused.

  • Engine cylinder head bolt set for OE-style head gasket service
  • Designed for Mercedes-Benz engines that require torque-to-yield head bolts
  • Supports proper cylinder head clamping force during reassembly
  • Direct replacement part for service work on Mercedes-Benz S350 and 300D applications
  • Victor Reinz part number 14-32031-03

Why This Part Matters

Head bolts play a critical role in sealing the cylinder head to the engine block. On torque-to-yield designs, the bolts are stretched during installation to create the clamping load needed for a secure head gasket seal. Victor Reinz 14-32031-03 is built for that service requirement and is the correct choice when replacing head bolts on 1994-1995 Mercedes-Benz S350 and 1987 Mercedes-Benz 300D applications. This part cross-references Elring 820.122 for the same application.

Common Repair Symptoms

  • Head gasket sealing concerns after cylinder head service
  • Reused torque-to-yield bolts during engine reassembly
  • Loss of proper clamping force at the cylinder head
  • Need for OE-style replacement hardware during engine repair

Installation Notes

Follow the factory tightening sequence and torque specifications for the specific Mercedes-Benz engine. Torque-to-yield head bolts are tightened in stages and must not be reused after removal. Verify cylinder head and block surfaces are clean and flat before installation. Fits 1994-1995 Mercedes-Benz S350, N/A. Fits 1987 Mercedes-Benz 300D, N/A.

Quality Assurance

Victor Reinz is a recognized sealing and engine hardware brand used in professional engine service. Part number 14-32031-03 is engineered for applications that require new torque-to-yield head bolts during cylinder head installation.
