Additional Notes

  • The Austin 3-Litre, ADO61 cooling system holds 10.8 liters under normal use conditions, a figure that reflects the base circuit without any auxiliary heating circuit included.
  • When the heater circuit is factored in, total coolant capacity rises to 12.2 liters, an increase of 1.4 liters that accounts for the additional volume held within the heater core and its connecting hoses.
  • The gap between the two capacity figures means that a service fill performed without purging the heater circuit would leave the system approximately 1.4 liters short of its full volume, which is a meaningful shortfall in a system of this size.
