Additional Notes

  • The MAN Bus and Coach chassis 14.290 HOCL carries a cooling system capacity of 49.4 liters, a figure consistent with large commercial vehicle engines where substantial thermal mass is needed to manage heat across extended operating cycles.
  • Across the Euro 5 (A67) variant introduced in 2014, the Euro 6b (A67) variant introduced in 2018, and the Euro 6c (A67) variant introduced in 2019, the cooling system capacity remains fixed at 49.4 liters, with no variation tied to emission standard generation.
  • The service interval for the cooling system is specified at 500,000 km or 48 months under normal use conditions, whichever comes first. At 500,000 km, the mileage threshold reflects the high-utilization duty cycles typical of coach and bus operations.
  • The 48-month time limit on the coolant change interval means the fluid is due for replacement after four years regardless of distance accumulated, which is relevant for vehicles that may not reach the mileage threshold within that period.
  • The Euro 5 (A67) 14.290 HOCL lists both a normal and a normal (alternative) use condition, each paired with the same 49.4-liter capacity and 500,000 km / 48-month interval, indicating that an alternative approved fluid type is available without any change to the service schedule or fill volume.
  • The Euro 6b and Euro 6c variants of the 14.290 HOCL list only the normal (alternative) use condition, each retaining the same 49.4-liter capacity and 500,000 km / 48-month interval as the Euro 5 specification.
