Additional Notes

  • The Acura TL UA4/UA5 cooling system holds 7.5 liters as a dry fill capacity. A dry fill figure represents the total volume of the entire cooling system when completely empty, such as after a full engine overhaul or major component replacement requiring a complete drain of all coolant passages.
  • The service fill capacity of 5.6 liters is notably lower than the dry fill figure. A service fill reflects the amount of coolant needed during a routine drain-and-refill procedure, where residual fluid remains in the engine block, heater core, and other passages that do not fully drain under gravity alone.
  • Under normal use conditions, the coolant change interval across all 2001-2003 TL 3.2 configurations is 96,000 km or 60 months, whichever comes first. The time-based limit of 60 months reflects the chemical degradation of coolant additives over time, independent of mileage accumulation.
  • A separate first change only interval of 192,000 km or 120 months applies to all 2001-2003 TL 3.2 configurations. This extended interval is specific to the initial factory-fill coolant, which in Honda and Acura vehicles of this era was typically a long-life formulation designed to outlast subsequent refills.
  • The 2001 model year TL 3.2 in both USA and CAN markets carries identical capacity and interval specifications to the 2002-2003 model years. The dry fill, service fill, normal interval, and first change only interval are unchanged across the full 2001-2003 span.
  • The TL 3.2 Type-S, available in both USA and CAN markets for 2002-2003, shares the same 7.5-liter dry fill, 5.6-liter service fill, 96,000 km/60-month normal interval, and 192,000 km/120-month first change only interval as the standard TL 3.2. No cooling system capacity or interval distinction exists between the base and Type-S trims in the specifications.
  • All configurations across both market regions (USA and CAN) carry identical coolant capacity and service interval values. The 7.5-liter dry fill, 5.6-liter service fill, and both change intervals are consistent regardless of whether the vehicle was sold in the United States or Canadian market.
