Lamborghini Rekord COM3

Additional Notes

• The Lamborghini Rekord COM3 cooling system holds 11 liters across all listed configurations, from the Rekord 40E through the Rekord 75.4E. In agricultural and industrial equipment, a consistent capacity figure across a range of engine variants typically reflects a shared cooling circuit architecture rather than engine-specific sizing.
• The 11-liter capacity figure represents a service fill volume, meaning the amount of coolant required to refill the system during a standard drain-and-fill service. Service fill volumes are generally lower than full overhaul or disassembly capacities, which account for residual fluid in components such as the engine block and heat exchangers.
• Coolant level checks are specified at every 10 operating hours under normal use conditions across all Rekord COM3 variants. A 10-hour check interval is notably short and reflects the demands placed on cooling systems in agricultural machinery, where sustained high-load operation accelerates coolant consumption and increases the risk of air ingestion or minor leaks going undetected.
• The coolant change interval is set at 1,200 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger format, combining an hours-based threshold with a calendar-based limit, accounts for machines that accumulate operating hours slowly, where coolant degradation occurs through chemical aging rather than thermal cycling alone.
• The Rekord 65 Stage 3A and Rekord 75 Stage 3A variants carry a starting serial number of 1001 and a model year range beginning in 2010, two years later than the 2008 start date of most other configurations in the lineup. Despite the later introduction, the cooling system capacity and service intervals for these Stage 3A variants are identical to the earlier configurations.
• Stage 3A designates an engine emissions compliance tier under European non-road mobile machinery regulations. The presence of Stage 3A variants alongside non-designated variants within the same model range indicates that the cooling system specifications were not altered to accommodate the emissions-related engine modifications introduced with that certification level.
• The "E" suffix appearing in several variant names, such as the Rekord 40E, 50E, 60E, 70E, and 75.4E, distinguishes specific sub-variants within the COM3 lineup. Across all "E" and non-"E" pairings where both exist, the cooling system capacity and service intervals remain at 11 liters, 10-hour checks, and 1,200-hour or 24-month changes.
