Additional Notes

  • The Hudson Pacemaker cooling system carries a base capacity of 17.8 liters, which represents the volume of coolant the system holds without an auxiliary cabin heater circuit included.
  • When a heater is fitted, the total coolant capacity rises to 18.7 liters, reflecting the additional fluid volume held within the heater core and its connecting hoses.
  • The difference between the base and heater-equipped capacities amounts to 0.9 liters, a figure that would factor into accurate refill measurements following a full system drain.
  • Under normal use conditions, the specified interval for a coolant level inspection is 1,000 miles, indicating a relatively frequent monitoring schedule tied to routine driving rather than severe or off-road operation.
