⚙️ Key Features

  • 0.991 kg
  • Supersedes 20845189
  • 17 applications across TD and TAD series engines
  • Also supersedes Volvo part number 20412283

🔌 Function

Holds the coolant that expands out of the circuit as the engine warms, and returns it on cooling.

⚠️ Common Signs of Failure

  • Coolant loss with no obvious external leak
  • Cracking or crazing of the tank body
  • Cap not holding the system pressure
  • Level swinging widely between hot and cold
  • Staining around the seams

🛠️ Service Notes

  • Check the cap as well as the tank — a cap that will not hold pressure produces the same symptoms
  • Only fill to the marked cold level; overfilling pushes coolant out as the engine warms
