Acura TL, UA6, UA7 (USA / CAN)
Coolant capacity & service interval
Acura TL, UA6, UA7 (USA / CAN) models require coolant with a capacity range of 6,3 to 8,2 liters. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| TL 3.5 Type-S (2007-2008) |
|
| TL 3.2 (2006-2008) |
|
| TL 3.2 (2004-2005) |

Additional Notes
- The Acura TL UA6/UA7 cooling system specifications list two distinct capacity figures for each configuration: a dry fill value and a service fill value. Dry fill represents the total system volume when completely empty, while service fill reflects the smaller amount needed during a routine coolant change, as some fluid remains in the system.
- The 3.2 engine in 2004-2005 trim carries a dry fill capacity of 7.9-8.1 liters, making it the lowest dry fill figure across all three listed configurations.
- From 2006 onward, the 3.2 engine's dry fill capacity increased to 8.0-8.2 liters, a modest but measurable shift compared to the 2004-2005 specification.
- The 2006-2008 3.2 and the 2007-2008 3.5 Type-S share identical capacity ranges of 8.0-8.2 liters dry fill and 6.4-6.5 liters service fill, despite being different engine displacements.
- The service fill figure for the 2004-2005 3.2 sits at 6.3-6.4 liters, meaning roughly 1.6-1.7 liters of coolant is expected to remain in the system during a standard drain-and-refill procedure.
- All three configurations carry a normal use condition designation, indicating the listed capacities and intervals apply to standard operating environments rather than severe or extended-duty cycles.
