Additional Notes

  • The Lotus Elise MK1 cooling system holds 8 liters of coolant, a figure that applies to both the standard Elise (1995-2001) and the higher-output 111S variant (1999-2001).
  • An 8-liter coolant capacity is consistent with a small-displacement sports car cooling circuit, where the volume accounts for the radiator, hoses, and engine block passages combined.
  • The specified change interval for both configurations is 24 months, meaning coolant renewal is tied to elapsed time rather than mileage accumulation.
  • A 24-month interval under normal use conditions reflects the degradation rate of corrosion inhibitors within the coolant, which lose effectiveness over time regardless of how many miles the vehicle has covered.
  • The 111S, introduced in 1999, shares an identical 8-liter capacity and 24-month service interval with the base Elise despite differences in engine tune, indicating no change to the cooling system volume between the two variants.
