Additional Notes

  • The Volvo FL-6 Euro 3 cooling system holds 30 liters across all three power variants — the FL 6-180, FL 6-220, and FL 6-250 — for the 2001-2006 model range.
  • A uniform 30-liter capacity across the 180, 220, and 250 horsepower configurations indicates no variation in cooling system volume despite the differences in engine output rating.
  • Under normal use conditions, the coolant change interval is set at 24 months, applying equally to all three power variants in the FL-6 Euro 3 lineup.
  • An alternative (acceptable) use condition carries a notably shorter change interval of 100,000 km, 12 months, or 2,000 hours — whichever comes first — compared to the 24-month normal interval.
  • The 12-month interval under alternative (acceptable) use is half the duration of the 24-month normal interval, reflecting a more demanding service schedule tied to that operating condition.
  • The inclusion of an hours-based threshold of 2,000 hours under the alternative (acceptable) condition is consistent with commercial vehicle applications where engine runtime, rather than distance, may be the primary measure of use.
  • The 100,000 km distance threshold under the alternative (acceptable) condition applies alongside the 12-month and 2,000-hour limits, meaning whichever of the three is reached first would trigger a service event.
