Additional Notes

  • The Acura TL (UA8/UA9) cooling system carries a dry fill capacity of 8.3 liters across all listed configurations and model years. Dry fill capacity represents the total volume of coolant required when filling a completely empty system, such as after a full engine overhaul or replacement of major cooling components.
  • Service fill capacity is rated at 6.3 liters across all configurations, reflecting the reduced volume needed during a routine coolant drain and refill. The 2.0-liter difference between dry and service fill values accounts for residual coolant that remains trapped in the engine block, heater core, and other passages during a standard service procedure.
  • All six configurations carry identical dry and service fill capacities, meaning the 3.5-liter and 3.7 SH-AWD variants share the same 8.3-liter dry and 6.3-liter service fill figures despite differing in displacement and drivetrain layout.
  • The 3.7 SH-AWD designation refers to the Super Handling All-Wheel Drive system, which adds rear drivetrain components not present in the front-wheel-drive 3.5 variants. The shared coolant capacity figures indicate the additional AWD hardware does not alter the cooling system volume.
  • All specifications are listed under normal use conditions, which in coolant service contexts typically refers to standard operating environments without the extended heat cycles or contamination exposure associated with severe-duty classifications.
  • The 2012 model year appears in both the 2011-2012 and 2012-2014 row groupings for both the 3.5 and 3.7 SH-AWD variants. In both cases the capacity figures remain at 8.3 liters dry and 6.3 liters service fill, so the overlap produces no difference in specified values for that year.
