Additional Notes

  • All three configurations listed for the Land Rover Defender LD (USA) share an identical cooling system capacity of 11.3 liters, applying equally to the 3.9 V8i variants from 1993-1995 and the 4.0 V8i from 1997-1998.
  • An 11.3-liter coolant capacity is consistent with a large-displacement V8 engine bay, reflecting the volume required to fill the block passages, cylinder heads, radiator, and associated hoses in a full-size off-road vehicle.
  • The service interval for all three configurations is set at 30,000 miles under normal use conditions, meaning the interval applies to standard operating environments rather than the more demanding cycles that would otherwise shorten the change frequency.
  • The Defender 110 3.9 V8i covers model years 1993-1994, while the Defender 90 3.9 V8i covers 1994-1995, indicating a one-year overlap in the 3.9-liter engine's production across the two body configurations.
  • The transition from the 3.9 V8i to the 4.0 V8i in the Defender 90 did not alter the cooling system capacity or the service interval, both remaining at 11.3 liters and 30,000 miles respectively.
