⚙️ Key Features

  • Coolant pipe for the closed-cooling system on D11B and D11C marine propulsion engines
  • 0.261 kg
  • Listed for 8 applications across the D range
  • Forms a rigid section of the thermostat, pump or heat-exchanger circuit

🔌 Function

Carries coolant along a fixed section of the closed circuit, holding the route between the thermostat, pump and heat exchanger so the flexible hoses only have to cover short movements.

⚠️ Common Signs of Failure

  • Coolant loss with a crusted white or coloured deposit at a joint
  • Header tank needing topping up with no obvious external leak
  • Temperature creeping up under load
  • Pipe pitted through or corroded thin on strip-down
  • Hose ends hardened and cracked where they grip the pipe

🛠️ Service Notes

  • Renew the hoses and clamps that land on this pipe at the same time - a corroded pipe has usually been weeping into them for a while
  • Check the pipe's sealing seats for pitting before fitting new hoses; a pitted seat will weep again
