Fenwick Forklift trucks, LPG (Evo series)

Coolant capacity & service interval

Fenwick Forklift trucks, LPG (Evo series) utilize coolant with a capacity range of 14 to 16,5 liters. Service intervals consist of a 10 hour check and a change every 24 months or 6000 hours. The data covers 6 configurations.

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

Additional Notes

All six Fenwick Forklift trucks, LPG (Evo series) configurations listed here share the Volkswagen 3.6-liter VR6 engine, a narrow-angle six-cylinder unit originally developed for passenger vehicles and adapted for industrial forklift applications.
The base cooling system capacity across the H50T, H60T, H70T, H80T, H80/900T, and H80/1100T models is 14 liters, representing the fill volume for the engine cooling circuit without an auxiliary cabin heater installed.
When a heater unit is fitted, the total cooling system capacity rises to 16.5 liters, reflecting the additional fluid volume held within the heater core and its connecting hoses.
The 2.5-liter difference between the standard and heater-equipped capacities is a relevant detail at service time, as underfilling a heater-equipped system to the base 14-liter figure would leave the circuit short of its designed volume.
Coolant level checks are specified at every 10 operating hours under normal use conditions, a notably short interval consistent with the demanding thermal cycles typical of LPG-powered forklift operation.
The coolant change interval is set at 24 months or 6,000 operating hours, whichever comes first, applying a dual time-and-usage trigger that accounts for both calendar-based fluid degradation and wear from active service hours.
The H50T, H60T, H70T, H80T, H80/900T, and H80/1100T models all carry identical cooling system specifications, indicating that the VW 3.6-liter VR6 installation is consistent across the full load-capacity range of the Evo series covered here.
The H80 designation appears in three distinct variants — H80T, H80/900T, and H80/1100T — which differ in load capacity ratings while sharing the same engine and cooling system specifications.
