| Item | Figure | Where it comes from |
|---|---|---|
| Coolant | Toyota Super Long Life Coolant, or a similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology. Do not use plain water alone. | Cooling system, coolant type |
| 2.7L 1AR-FE | 10.7 qt. (10.1 L, 8.9 Imp. qt.). Reference. | Cooling system capacity |
| 3.5L 2GR-FKS, without Stop and Start | 12.9 qt. (12.2 L, 10.7 Imp. qt.). | Cooling system capacity |
| 3.5L 2GR-FKS, with Stop and Start | 13.0 qt. (12.3 L, 10.8 Imp. qt.). | Cooling system capacity |
The 1AR-FE cooling capacity is 10.7 qt. (10.1 L, 8.9 Imp. qt.).
Without Stop and Start the 2GR-FKS is 12.9 qt. With Stop and Start it is 13.0 qt.
The coolant is Toyota Super Long Life Coolant or a similar long-life hybrid-organic-acid coolant that is non-silicate, non-amine, non-nitrite, and non-borate.
No bleed sequence is printed in the cooling-system table, so none is added. The two 3.5L rows stay separate because the manual prints both.
