Fenwick Forklift trucks, LPG (394 series)

Coolant capacity & service interval

Fenwick Forklift trucks, LPG (394 series) require coolant with a capacity range of 10,5 to 12,5 liters. Service intervals include checking every 10 hours and changing every 60 months or 12000 hours, or every 12000 hours. The data covers 6 configurations.

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

Additional Notes

  • Across all six configurations of the Fenwick Forklift trucks, LPG (394 series), the base cooling system capacity is 10.5 liters. This figure represents the standard fill volume without any auxiliary heating circuit connected.
  • When a cab heater is fitted, the total coolant capacity rises due to the additional volume held in the heater core and its connecting hoses. The 394-01 variants specify 12.5 liters in that configuration, while the 394-02 variants specify a slightly lower 12 liters.
  • The 0.5-liter difference in heater-equipped capacity between the 394-01 and 394-02 series suggests a minor change in heater circuit volume between the two generations, even though the base 10.5-liter figure remains identical across both.
  • All six configurations share a coolant level check interval of every 10 hours of operation under normal use conditions. For industrial equipment operating in multi-shift environments, a 10-hour check interval corresponds roughly to a daily inspection cycle.
  • The 394-01 variants covering the H40 T, H45 T, and H50/500 T specify a coolant change interval expressed as a dual condition: 60 months or 12,000 hours, whichever comes first. The time-based limit of 60 months equates to five years, acknowledging that coolant degrades chemically over time regardless of machine hours accumulated.
  • The 394-02 variants covering the H40 T, H45 T, and H50/600 T list only a 12,000-hour change interval, with no corresponding month-based limit stated. This contrasts with the 394-01 dual-condition approach and removes the calendar-based trigger from the service requirement.
  • The H50 model designation differs between the two series generations: the 394-01 series lists the H50/500 T, while the 394-02 series lists the H50/600 T. Both share the same VW BMF engine and carry identical capacity figures within their respective series.
