Toyota Sienna Fluid Capacities by Year
Sienna fluid tables change with the hybrid generation, FWD or AWD, towing equipment, and the specific service operation. The examples below keep the manual’s application labels visible so one system’s amount is not mistaken for another.
Use these as manual-table reference quantities for the exact selection linked below. Some capacities are approximate or identified by Toyota as reference quantities; they are not automatically the amount for a drain-and-refill service. Confirm your year, trim, drive type, towing package, and VIN where shown.
Why the 2024 hybrid coolant figures must be separated
The 2024 Sienna LE 2.5L manual lists two rows both named “Engine Coolant,” but the Application column distinguishes the gasoline engine from the Power Control Unit. The 2.00 qt figure is for the Power Control Unit loop; the manual separately lists 11.40 qt for the gasoline engine loop.
Swipe the table sideways to see every column.
| 2024 Sienna LE 2.5L VIN R | Manual table amount | Application / note |
|---|---|---|
| Engine coolant | 11.40 qt (10.78 L) | Gasoline Engine |
| Engine coolant | 2.00 qt (1.89 L) | Power Control Unit |
| Engine oil drain and refill | 4.50 qt with filter; 4.20 qt without filter | SAE 0W-16. Toyota allows 0W-20 if unavailable, with 0W-16 required at the next oil change. |
| Automatic transmission fluid | 4.60 qt (4.35 L) | Toyota Genuine ATF WS; the source cautions against other fluid. |
| Differential gear oil | 1.80 qt (1.70 L) | Rear electronic motor; approximate capacity; Toyota Genuine ATF WS. |
2021–2023 hybrid examples
The checked 2021, 2022 and 2023 Sienna LE 2.5L VIN R tables also separate the gasoline-engine and Power Control Unit coolant loops. Their engine-oil refill figures differ from the 2024 table, so the 2024 amount should not be carried backward.
Swipe the table sideways to see every column.
| Manual selection | Engine coolant | Power Control Unit coolant | Engine oil drain/refill |
|---|---|---|---|
| 2021 LE 2.5L VIN R | 11.40 qt (10.78 L) | 2.00 qt (1.89 L) | 4.80 qt with filter; 4.40 qt without |
| 2022–2023 LE 2.5L VIN R | 11.40 qt (10.78 L) | 2.00 qt (1.89 L) | 4.80 qt with filter; 4.40 qt without |
These manuals specify SAE 0W-16 engine oil. For the hybrid transaxle, the table lists 4.60 qt ATF WS; the rear electronic motor gear-oil row lists 1.80 qt and marks it approximate.
2018–2020 V6 examples: towing package and AWD matter
The checked 2018, 2019 and 2020 LE tables list a 3.5L V6. Engine coolant and oil with filter have separate no-tow and towing-package quantities. FWD and AWD tables list 7.90 qt ATF WS; the AWD table also lists 0.50 qt for the rear differential.
Swipe the table sideways to see every column.
| Manual selection | Engine coolant | Engine oil, drain/refill | Transmission / AWD |
|---|---|---|---|
| 2018–2020 LE 3.5L FWD | 12.20 qt without towing package; 12.50 qt with | 5.70 qt with filter/no tow; 5.80 qt with filter/tow; 5.60 qt without filter | 7.90 qt ATF WS; no AWD rear-differential row in FWD table |
| 2018–2020 LE 3.5L AWD | 12.20 qt without towing package; 12.50 qt with | 5.70 qt with filter/no tow; 5.80 qt with filter/tow; 5.60 qt without filter | 7.90 qt ATF WS; rear differential: 0.50 qt gear oil |
For the 2018–2020 source tables, Toyota describes the ATF capacity as a reference quantity. Use the vehicle-specific service procedure to determine the service-fill amount.
2017 V6 examples
The checked 2017 LE FWD and AWD tables list 8.00 qt ATF WS. Coolant is 12.20 qt without the towing package or 12.50 qt with it. Oil drain/refill with filter is 5.70 qt without towing and 5.80 qt with towing; without filter the table lists 5.60 qt. AWD adds a 0.50 qt rear differential gear-oil row.
2015–2016 V6 examples
The checked 2015 and 2016 LE tables list different ATF reference quantities for FWD and AWD: 6.90 qt FWD and 7.10 qt AWD. Both tables show 11.00 qt engine coolant without the towing package and 11.70 qt with it. Engine-oil drain/refill is 6.40 qt with filter or 6.00 qt without. The AWD table also lists 0.50 qt rear differential gear oil.
Choose the exact manual before buying fluid
These are manual-listed specifications, not a confirmation that a particular container or kit fits every Sienna. Match the year, hybrid or V6 powertrain, FWD/AWD, towing package, oil-filter service, and VIN details where provided. Do not use a total/reference capacity as a drain-and-refill quantity.
