⚙️ Key Features

• Heat exchanger to exhaust bend
• 0.24 kg
• 28 applications across AD, D, TMD, DP, DPX and SP series

🔌 Function

Carries coolant between the heat exchanger and the exhaust bend so the exhaust elbow is kept cooled.

⚠️ Common Signs of Failure

• Coolant weeping or steaming at the exhaust bend end
• Salt crust and staining along the pipe
• Pipe corroded through, often worst nearest the exhaust heat
• Exhaust bend running hotter than usual as flow drops
• Bore silted or scaled, restricting coolant

🛠️ Service Notes

• Inspect the exhaust bend itself while the pipe is off — the two corrode at similar rates
• Fit new seals at both ends and pressure test before running up

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
