Additional Notes

  • The 1500 and 1800 C10 variants, both spanning 1968-1972, share an identical cooling system capacity of 6.8 liters, indicating the same basic engine bay packaging and cooling architecture across those two displacement options.
  • The 2000 GT GC10 and 2400 GT GC10 each carry a 9-liter cooling system capacity, a notable step up from the 6.8-liter figure of the earlier 1500 and 1800 C10 configurations, reflecting the greater thermal load associated with the larger displacement engines.
  • The Datsun (Nissan) Skyline 240K GT GC110, covering 1972-1977, holds the largest cooling system capacity in the specifications at 9.5 liters, suggesting a more demanding heat rejection requirement compared to the GC10-generation GT variants at 9 liters.
  • All five configurations share a uniform coolant change interval of 40,000 km under normal use conditions, applying consistently across the full range from the 1968 C10 through the 1977 GC110.
  • The 2400 GT GC10 is listed solely within 1972, placing the entire production window within a single calendar year, while still carrying the same 9-liter capacity and 40,000 km interval as the 2000 GT GC10 from 1971-1972.
  • The capacity increase from 6.8 liters in the C10 base models to 9 liters in the GC10 GT variants represents a difference of 2.2 liters, a meaningful volume when considering the total coolant volume circulating through the engine block, cylinder head, and radiator.
