Volvo Light cross-country truck series (EU)

Power steering fluid capacity & service interval

Volvo Light cross-country truck series (EU) power steering fluid capacity ranges from 0,3 to 0,5 liter. Service intervals include 2500 km and 5000 km/ 6 months. The data covers 4 configurations.

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

Additional Notes

  • The C303 (TGB11xx), C304 (TGB13xx), and C306 (TGB21/22) configurations all share an identical steering box capacity of 0.5 liter, indicating a consistent fluid volume requirement across the 1974-1984 generation of these cross-country variants.
  • The L3314 (Välp) and PLTGB903, covering the 1962-1977 period, carry a steering box capacity of 0.3 liter, which is 40 percent lower than the 0.5 liter figure specified for the later C303, C304, and C306 models.
  • All four configurations reference a steering box rather than a rack-and-pinion or hydraulic pump reservoir, meaning the fluid capacity figure in each row reflects the volume held within the steering gear housing itself.
  • The C303, C304, and C306 share a check interval of 5000 km or 6 months under normal use conditions, whichever comes first, combining both a distance and a time-based threshold for the same service action.
  • The L3314 and PLTGB903 specify a check interval of 2500 km under normal use conditions, a distance-only interval with no accompanying time-based threshold, and one that is half the 5000 km distance specified for the later models.
