Additional Notes

  • The Fiat 133 (EU) cooling system holds 7.5 liters, a figure that reflects the total system capacity including the radiator, hoses, and engine block passages rather than a partial service top-up volume.
  • A check interval of 500 km is specified under normal use conditions, indicating that coolant level verification is expected very frequently relative to the change interval.
  • The change interval is set at 60,000 km or 24 months under normal use, meaning whichever threshold arrives first would trigger a full coolant replacement.
  • The 24-month time limit on the change interval reflects the chemical degradation of coolant additives over time, which occurs independently of mileage accumulation.
  • A single specification row covers the entire 1974-1982 production span, indicating no variation in cooling system capacity or service intervals across those model years.
