Lamborghini Grand Prix
Coolant capacity & service interval
Lamborghini Grand Prix coolant capacity ranges from 11 to 13 liters. Service intervals require changes every 2400 hours or 24 months. The data covers 3 configurations.

Additional Notes
- The Lamborghini Grand Prix 674-70 and 674-70 DT cooling systems hold 13 liters, a capacity typical of larger agricultural or industrial engines where extended thermal management is required across long operating cycles.
- The Grand Prix 774-80 and 774-80 DT carry a notably smaller cooling system capacity of 11 liters compared to the 674-70 and 874-90 variants, both of which share a 13-liter figure.
- The Grand Prix 874-90 and 874-90 DT cooling system capacity matches the 674-70 series at 13 liters, despite the higher numeric designation in the model name suggesting a larger or more powerful engine configuration.
- Across all three model variants covering the 1986-1995 production span, the coolant change interval is uniformly set at 2,400 hours or 24 months under normal use conditions, whichever comes first.
- The 2,400-hour threshold reflects a time-based operational measure common in agricultural and industrial equipment, where engine hours rather than mileage serve as the primary metric for service scheduling.
- The 24-month calendar interval runs parallel to the 2,400-hour mark, meaning a unit with low annual operating hours would still require a coolant change within two years regardless of accumulated engine time.
- All three configurations, the 674-70, 774-80, and 874-90 series, share identical service interval specifications under normal use, with no differentiation in change frequency based on engine size or displacement class.
