Sinotruk HOWO Heavy-Duty Exhaust Pipe Fastening Bolt (Part No. VG1246110052)

The VG1246110052 Exhaust Pipe Fastening Bolt is a critical component within the HOWO parts catalog, specifically designed to handle the brutal thermal expansion and contraction cycles of a heavy-duty diesel exhaust system.

Technical Specifications

As experienced suppliers of HOWO parts, we recommend the following for installation:

1. Use Anti-Seize: Always apply a small amount of high-temperature copper anti-seize to the threads of the VG1246110052 bolt. This prevents the bolt from welding itself to the manifold over time.

2. Torque to Spec: Do not over-tighten. Follow the Sinotruk service manual's torque settings to avoid stripping the threads in the engine head.

3. Replace in Sets: If one exhaust bolt has failed due to heat stress, others are likely close behind. We recommend replacing the entire set to ensure uniform pressure across the exhaust flange
