Audi A5, S5 Cabriolet, F57 / F5E (USA)

Coolant capacity & service interval

Audi A5, S5 Cabriolet, F57 / F5E (USA) models require 10 liters of coolant. Service intervals for coolant checks occur every 20000 miles or 24 months. The data covers 5 configurations.

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

Additional Notes

  • Across all listed Audi A5 and S5 Cabriolet F57 / F5E configurations for the USA market, the cooling system capacity is uniformly 10 liters, which represents a full system fill volume rather than a partial top-up quantity.
  • A 10-liter cooling system capacity is consistent with a mid-size turbocharged engine layout, where the system encompasses the engine block, cylinder head passages, heater core circuit, and expansion reservoir.
  • The A5 Cabriolet 2.0 TFSI quattro at 185 kW covers model years 2017-2018, while a same-displacement variant badged as the 45 TFSI quattro at the same 185 kW rating carries the 2018-2020 range, reflecting a nomenclature change rather than an engineering one, with both sharing the identical 10-liter capacity and check interval.
  • The A5 Cabriolet 45 TFSI quattro at 195 kW, introduced from 2020, represents a power increase of 10 kW over the preceding 185 kW variant, yet the cooling system capacity remains at 10 liters under normal use conditions.
  • The S5 Cabriolet 3.0 TFSI quattro at 260 kW carries a significantly higher output than any A5 variant listed, yet the cooling system capacity is specified at the same 10 liters, indicating the shared platform accommodates both engine families within the same coolant volume envelope.
  • All five configurations share a single check interval of 20,000 miles or 24 months under normal use conditions, meaning the interval is defined by whichever threshold is reached first.
  • The specified interval is a check interval rather than a replacement interval, meaning the 20,000-mile or 24-month mark calls for an inspection of coolant condition and level rather than a mandatory full system drain and refill.
