Additional Notes

  • The Mazda RX-7 Twin Turbo FD carries a coolant system capacity of 8.7 liters, which represents a full cooling system fill rather than a partial service top-up.
  • A 24-month change interval applies under normal use conditions, meaning the coolant replacement cycle is time-based rather than tied to a mileage threshold.
  • The 8.7-liter figure reflects the demands of a twin-turbocharged rotary engine, where thermal management requirements across the turbocharger circuit and rotor housings contribute to a relatively large coolant volume for a sports car of this displacement class.
