Austin Metro

Coolant capacity & service interval

The Austin Metro coolant capacity is 4.8 liters. The coolant should be changed every 40,000 kilometers or 48 months. The data covers 6 configurations of the Austin Metro model.

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

Additional Notes

  • All Austin Metro configurations listed across the 1983-1990 period share a uniform cooling system capacity of 4.8 liters, which is consistent with the small-displacement engines found in compact city cars of that era.
  • A 4.8-liter cooling system capacity reflects a service fill figure, representing the total volume of coolant the system holds during normal operation rather than a dry-fill or overhaul measurement that might account for residual fluid in components.
  • The coolant change interval across all listed configurations is 40,000 km or 48 months under normal use conditions, meaning the interval applies to standard driving environments rather than severe or demanding operating conditions.
  • The 48-month time limit on the coolant change interval means that even when mileage accumulation is low, the coolant is due for replacement at the four-year mark, reflecting the chemical degradation of antifreeze and corrosion inhibitors over time regardless of distance traveled.
  • The Austin Metro 1.0 and 1.3 engine variants carry identical cooling system capacities of 4.8 liters, indicating no meaningful difference in cooling circuit volume between the two engine displacements across either the 1983-1986 or 1986-1990 production periods.
  • The Metro Vanden Plas, a higher-trim variant, shares the same 4.8-liter capacity and 40,000 km / 48-month interval as the standard 1.0 and 1.3 models, reflecting that trim level differences did not affect the cooling system specification.
  • Specifications are divided into two production sub-periods, 1983-1986 and 1986-1990, across all three configurations, yet the cooling system capacity and change interval remain unchanged between those sub-periods for every variant listed.
