Volvo Light cross-country truck series (EU)

Differential fluid capacity & service interval

Volvo Light cross-country truck series (EU) differential fluid capacity is 1,5 liters. Service intervals include checks at 1250 km, 5000 km or 6 months, and changes at 10000 km or 30000 km or 12 months. The data covers 8 configurations.

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

Additional Notes

  • Across all configurations in the Volvo Light cross-country truck series (EU), both the front and rear differentials share an identical fluid capacity of 1.5 liters, meaning neither axle requires a greater fill volume than the other.
  • The C303, TGB11(xx), C304, TGB13(xx), and C306, TGB21/22 models, all covering the 1974-1984 period, specify a fluid check interval of every 5,000 km or 6 months under normal use conditions, whichever comes first.
  • For the same 1974-1984 configurations, the fluid change interval under normal use is set at 30,000 km or 12 months, pairing a distance-based threshold with a fixed annual calendar limit.
  • The L3314 (Välp), PLTGB903 covering 1962-1977 carries a notably shorter check interval of 1,250 km compared to the 5,000 km interval specified for the later 1974-1984 models, reflecting a more frequent inspection requirement on the older platform.
  • The L3314 (Välp), PLTGB903 also specifies a fluid change interval of 10,000 km, which is one-third of the 30,000 km interval assigned to the later C303, C304, and C306 configurations, indicating a considerably more intensive service schedule on the earlier model.
  • Unlike the 1974-1984 configurations, the L3314 (Välp), PLTGB903 check and change intervals are expressed in distance only, with no calendar-based interval listed alongside the mileage figures.
  • The front and rear differential specifications are identical in both capacity and service intervals for every configuration listed, meaning no asymmetric axle loading or design difference between the two differentials is reflected in the fluid service data.
