Additional Notes

  • The Land Rover Discovery 1 LJ (USA) coolant system capacity of 11.3 liters applies to both the 3.9 V8i and the 4.0 V8i engine variants, indicating a shared cooling system architecture across the full 1993-1998 model range covered here.
  • An 11.3-liter cooling system capacity is a relatively large figure, consistent with the demands of a V8 engine in a body-on-frame SUV, where the coolant volume must manage heat across a long block, a sizable radiator, and heater circuits.
  • The 3.9 V8i, produced for the 1993-1995 period, carries the same 11.3-liter capacity as the later 4.0 V8i, which entered production in 1995 and continued through 1998, suggesting the displacement increase between the two engines did not require a change in cooling system volume.
  • The service interval for coolant replacement is rated at 30,000 miles under normal use conditions for both engine variants, meaning the interval reflects standard operating environments rather than the more demanding cycles associated with severe-use classifications.
  • A 30,000-mile coolant change interval was a common industry standard for the era, typically associated with conventional ethylene glycol antifreeze formulations, which degrade in corrosion inhibitor effectiveness over time and mileage at a faster rate than extended-life coolant chemistries introduced later.
