Additional Notes
- Both the FH 420 LNG Euro 6 and FH 460 LNG Euro 6, each fitted with the G13 engine and introduced from 2017, share an identical power steering fluid capacity of 4 liters under normal use conditions.
- A 4-liter capacity in a heavy truck power steering system is a relatively modest reservoir volume, consistent with a sealed or semi-sealed hydraulic assist circuit rather than a high-volume open system.
- The normal use condition tied to the 4-liter figure means the specification applies to standard operating environments, as opposed to severe-duty cycles that would carry separate service parameters.
- The G13 engine designation is shared across both the 420 and 460 LNG variants, and neither variant deviates from the 4-liter power steering fluid figure, indicating the output difference between the two does not affect the hydraulic steering circuit capacity.
