Additional Notes

  • The Lotus Elan M100 cooling system holds 6.25 liters across all three configurations covered in the 1989-1992 specifications, including the base Elan, the SE Turbo, and the SE Turbo with catalyst.
  • A 6.25-liter coolant capacity is consistent with a small-displacement front-wheel-drive sports car, reflecting the relatively compact 1.6-liter Isuzu-sourced engine shared across the M100 lineup.
  • The coolant change interval is set at 24 months under normal use conditions for all three configurations, meaning a full drain and refill of the 6.25-liter system is due every two years.
  • A separate 6-month check interval runs alongside the 24-month change schedule under normal use, indicating that coolant condition and level are monitored more frequently than the full replacement cycle.
  • The SE Turbo variant, introduced in 1990, carries the same 6.25-liter capacity and identical service intervals as the naturally aspirated base Elan, despite the added thermal load of forced induction.
  • The SE Turbo with catalyst, which entered the specifications in 1991, also shares the 6.25-liter capacity and the 6-month check plus 24-month change schedule, aligning with the other two configurations in both volume and service timing.
