This is a convoluted exhaust hose designed to connect the exhaust manifold or turbocharger to the exhaust system on Volvo trucks. It is constructed from durable, heat-resistant materials to withstand high exhaust temperatures and vibrations, unlike a worn hose that may crack or leak. Operators will typically observe loud exhaust leaks, a rattling noise, or a visible tear in the hose when it fails.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing exhaust hose is often an audible exhaust leak, characterized by a hissing or puffing sound. If ignored, the leak can worsen, leading to increased noise levels and potentially exhaust fumes entering the cabin. Continued operation with a compromised hose risks further damage to the exhaust system and potential exposure to harmful gases.
Ensure both connection points are clean and free of rust or debris before attaching the new hose. Avoid twisting the hose during installation, as this can create stress points and reduce its lifespan.
Inspect the exhaust manifold and muffler connections for signs of corrosion or damage when replacing the exhaust hose.
