Fenwick Forklift trucks, diesel (392 series)
Coolant capacity & service interval
Fenwick Forklift trucks, diesel (392 series) require coolant with a capacity range of 6 to 8 liters. Service intervals include a check every 10 hours and a change every 9000 hours. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Fenwick Forklift trucks, diesel (392 series) H20D and H25D variants, both fitted with the 392-02 / VW BXT engine from 2015, share identical cooling system capacities of 6 liters in the base configuration.
- When a heater unit is installed on either the H20D or H25D, the cooling system capacity rises to 8 liters, reflecting the additional fluid volume required to circulate through the heater circuit.
- A 2-liter difference between the base and heater-equipped fills represents a meaningful volume distinction, as service personnel filling to the base figure on a heater-equipped unit would leave the system short by roughly 25 percent of total capacity.
- The check interval for the cooling system on both configurations is set at every 10 hours of operation under normal use conditions, indicating a high-frequency inspection requirement consistent with the demanding duty cycles typical of industrial forklift applications.
- The coolant change interval is specified at 9,000 hours under normal use conditions for both the H20D and H25D, a figure that, in continuous multi-shift forklift operation, can represent several years of service before a full drain and refill is due.
