Additional Notes
- The Volvo Light cross-country truck series (EU) coolant system capacities split into two distinct values across the model range: 12 liters for the later military utility vehicles and 8.5 liters for the earlier L3314 (Välp), PLTGB903.
- The C303, TGB11(xx) covering 1974-1984 carries a cooling system capacity of 12 liters under normal use conditions.
- The C304, TGB13(xx) from 1974-1984 shares the same 12-liter cooling system capacity as the C303, reflecting a common engine cooling architecture across those two variants.
- The C306, TGB21/22 from 1974-1984 also specifies a 12-liter cooling system capacity under normal use conditions, consistent with the other TGB-designated models of the same production period.
- The L3314 (Välp), PLTGB903 from 1962-1977 specifies a notably smaller 8.5-liter cooling system capacity, which corresponds to a smaller or less thermally demanding engine configuration relative to the 12-liter TGB-series vehicles.
- All four configurations carry normal use conditions for their coolant capacity specifications, meaning the stated fill volumes apply to standard operating environments rather than severe-duty or first-change scenarios.
- The 3.5-liter difference between the 8.5-liter L3314 and the 12-liter TGB-series models represents a meaningful variation in cooling system volume, with larger capacities generally indicating greater thermal mass and longer heat dissipation capacity in the engine bay.
