Coolant capacity & service interval

BMW Z1 models require 10,5 liters of coolant. Service intervals occur every 48000 km or 24 months. The data covers 1 configuration.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The BMW Z1 cooling system holds 10.5 liters of coolant, which reflects the total capacity of the entire cooling circuit including the radiator, engine block passages, heater core, and expansion tank.
  • A single capacity figure of 10.5 liters applies across the 1988-1992 production span, indicating no variation in cooling system volume between model years.
  • The 10.5-liter figure represents a full system fill, the kind of volume associated with a complete drain and refill rather than a partial top-up.
  • The specified change interval runs to 48,000 km or 24 months, whichever comes first, and applies under normal use conditions.
  • The 24-month time limit means coolant replacement is due within two years regardless of whether the 48,000 km distance threshold has been reached, since coolant additives degrade over time independently of mileage accumulation.
