Additional Notes

  • The Audi Cabriolet B3 (USA) cooling system holds 11 liters across both the 1994-1996 and 1996-2000 variants of the 2.8 V6 (128 kW), indicating a consistent total system volume regardless of model year revision.
  • An 11-liter coolant capacity is relatively substantial for a six-cylinder engine of this displacement, reflecting the full volume of the engine block, cylinder head passages, radiator, heater core, and associated hoses that make up the complete cooling circuit.
  • The 1996-2000 2.8 V6 (128 kW) configuration carries a coolant check interval of every 7,500 miles or 12 months, whichever comes first, under normal use conditions.
  • The pairing of a mileage interval with a fixed time interval of 12 months for the 1996-2000 variant means the coolant level and condition are evaluated on an annual basis even in low-mileage situations where the distance threshold has not been reached.
  • No check interval is listed for the 1994-1996 2.8 V6 (128 kW) variant, while the 1996-2000 version of the same engine and capacity rating does carry one, marking a specification difference between the two production periods despite identical system volumes.
