Hudson Wasp

Coolant capacity & service interval

Hudson Wasp coolant capacity ranges from 12,3 liters to 18,7 liters. Service intervals require a check every 1000 miles. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Hudson Wasp cooling system capacity for the 1952-1954 Super Wasp and standard Wasp configurations is 17.8 liters without a heater, rising to 18.7 liters when a heater is included in the circuit.
  • The additional 0.9 liters required by the heater-equipped 1952-1954 configurations reflects the volume of coolant needed to fill the heater core and its connecting hoses alongside the main cooling circuit.
  • Both the Super Wasp and standard Wasp for 1952-1954 share identical cooling system capacities, indicating no differentiation in cooling circuit volume between those two trim levels during that period.
  • The 1955-1956 Wasp carries a noticeably smaller base cooling capacity of 12.3 liters, compared to the 17.8 liters specified for the 1952-1954 models, representing a reduction of 5.5 liters between the two generation spans.
  • With a heater installed, the 1955-1956 Wasp cooling system capacity reaches 13.2 liters, maintaining the same 0.9-liter heater increment seen in the earlier 1952-1954 specifications.
  • All three configurations carry a check interval of 1,000 miles under normal use conditions, which is a relatively short inspection interval consistent with maintenance practices common to mid-century vehicles.
