Jeep MB / GPW

Coolant capacity & service interval

Jeep MB / GPW requires coolant with a capacity of 10,4 liters. Service intervals occur every 20000 km or 6 months. The data covers 2 configurations.

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

TypeSpecifications
Ford Model GPW (1941-1945)
  • Use: Normal
  • Capacity 10,4 liter
  • Change 20000 km/ 6 months
Willys- Overland model MB (1941-1945)
  • Use: Normal
  • Capacity 10,4 liter
  • Change 20000 km/ 6 months

Additional Notes

  • Both the Ford Model GPW and the Willys-Overland Model MB share an identical coolant system capacity of 10.4 liters, which reflects a full cooling system fill volume rather than a partial service top-up.
  • The Jeep MB / GPW coolant change interval is set at 20,000 km or 6 months, whichever comes first under normal use conditions, meaning the time-based threshold of 6 months can trigger a change before the distance figure is reached.
  • A 10.4-liter cooling system capacity is relatively modest by modern standards, consistent with the small-displacement four-cylinder Go Devil engine shared across both the GPW and MB variants during the 1941-1945 production span.
  • The normal use condition tied to the 20,000 km / 6-month interval applies equally to both the Ford GPW and the Willys-Overland MB, with no differentiation in service scheduling between the two manufacturer variants.
