Additional Notes

  • Cooling system capacities across the Claas Mega range span from 36,5 liters to 43,3 liters, reflecting differences in engine displacement and the physical size of the cooling circuit associated with each drivetrain configuration.
  • The DO 202 Mega I/II accepts 36,5-38,5 liters regardless of whether the Mercedes-Benz OM 366A or the Perkins 1006.6T engine is fitted, indicating that the two engine options share an equivalent cooling system volume in that model variant.
  • The DO 203 Mega I/II specifies a capacity range of 38,5-40 liters, again consistent across both the Mercedes-Benz OM 366A and Perkins 1006.6T engine options, and represents a step up from the DO 202 figure.
  • A capacity range rather than a fixed value, as seen on the DO 202 and DO 203 variants, typically accounts for variables such as the presence of a cab heater circuit or auxiliary cooling components that may or may not be part of a given machine's configuration.
  • The DO 208 Mega I/II carries the highest specified coolant capacity in the 1992-1999 group at 43,3 liters, while the DO 218 Mega I/II is close behind at 43 liters, both substantially above the DO 202 and DO 203 figures.
  • All 1992-1999 configurations share a 12-month coolant change interval under normal use conditions. An annual change interval is standard practice for agricultural machinery that operates seasonally, ensuring corrosion inhibitors and freeze protection remain effective across varying ambient temperatures.
  • The Mega 350 and Mega 360 from 2003-2008 list fixed single-value capacities of 37 liters and 36,5 liters respectively, in contrast to the range values specified for the earlier DO 202 and DO 203 variants.
  • No coolant change interval is listed for the Mega 350 and Mega 360, whereas all 1992-1999 variants carry an explicit 12-month change specification under normal use conditions.
