856894 Exhaust Manifold | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta exhaust manifold from the Inlet and Exhaust System group, weighing 11.816 kg and listed for six applications. It supersedes 856137, which was catalogued earlier as an exhaust pipe - so a customer working from the older number may be expecting a pipe rather than the manifold now supplied. At 11.816 kg it is a freight-scale item.

🔌 Function

Collects the exhaust gas from the cylinder ports and carries it, water-jacketed, to the riser or exhaust pipe.

⚠️ Common Signs of Failure

• Exhaust ticking or blowing at the head face
• Soot fanning out from a port joint

• Coolant or seawater loss traced to the manifold
• Water carrying back towards the cylinders

🛠️ Service Notes

• Renew the head-face and outlet gaskets and check every face for flatness
