How much coolant does a Toyota Tundra take?
A typical Toyota Tundra requires about 11 quarts (roughly 10.5 liters) of coolant for a full cooling-system fill. Exact capacity varies by engine and year, so consult the owner's manual for your specific model.
Cooling system capacity by engine
The cooling capacity varies with the Tundra's engine. The figures below reflect common specifications reported by Toyota for the main engine options used in production in recent years.
- 4.0L V6 (1GR-FE) engine (2007–2021 Tundra): approximately 11.0 quarts (about 10.4 liters) for a full cooling-system fill, including radiator, hoses, and heater core.
- 3.5L i-Force twin-turbo V6 engine (2022–present Tundra): approximately 11.8–12.0 quarts (about 11.2–11.3 liters) for a full fill.
These figures represent a full fill of the cooling system. Your actual needs can vary slightly based on model year, aftermarket components, or if only part of the system is being refilled. Always verify with the official manual or dealer data for your exact vehicle.
How to refill or top off coolant
When refilling, use the recommended premixed coolant (typically a 50/50 mix of ethylene glycol-based coolant and distilled water) unless your manual specifies a different ratio. The steps below outline a safe refill and air-bleed process.
- Ensure the engine is completely cool and the vehicle is on a level surface. Engage the parking brake and remove the radiator cap only if it is safe to do so.
- Place a drain pan under the radiator drain valve and open it to remove old coolant. Collect and dispose of it according to local regulations.
- Inspect hoses, clamps, and the radiator for leaks. If needed, flush the cooling system with distilled water to remove any residue.
- Close the drain, reconnect any components, and begin refilling through the radiator or the coolant reservoir with the premixed coolant until the system is near the recommended level.
- Start the engine with the radiator cap off and allow it to reach operating temperature, then gently rev to help purge air. Add coolant as needed to maintain the proper level in the reservoir; watch for bubbles that indicate air pockets being released.
- Shut off the engine, wait for it to cool, recheck the level, and top off to the indicated mark on the reservoir. Recycle or dispose of any remaining old coolant properly.
Following these steps helps ensure the cooling system is correctly filled and air-bleed is complete, reducing the risk of overheating.
Summary
Across its recent generations, the Toyota Tundra generally takes about 11 quarts (approximately 10.5 liters) of coolant for a full system fill, with small variations by engine type and year. For the exact specification for your particular vehicle, refer to the owner’s manual or Toyota service data for your model year and engine configuration.
How much is a coolant change for a tundra?
between $318 and $375
The average cost for a Toyota Tundra Coolant Change is between $318 and $375. Labor costs are estimated between $122 and $180 while parts are typically priced around $196.
What coolant does a Toyota Tundra take?
The recommended coolant for a Toyota Tundra is Toyota Super Long Life Coolant (SLLC), which is typically pink in color. For older models, Toyota red coolant was used, but it is not interchangeable with the pink SLLC. Always use the genuine Toyota coolant or a compatible equivalent with similar specifications to avoid mixing and potential damage.
Coolant types
- Toyota Super Long Life Coolant (SLLC): This is the recommended coolant for most modern Tundra models (2007-2025) and is typically pink. It has a longer service life, with the first change recommended after 100,000 miles or 10 years, and subsequent changes every 50,000 miles or 5 years.
- Toyota Red Coolant: Used in older Tundra models, this coolant is not compatible with SLLC and requires more frequent changes. Do not mix the two.
- Compatible Equivalents: You can use an equivalent SLLC coolant that meets the same specifications, such as a pink, phosphated hybrid OAT (P-HOAT) coolant formulated for Asian vehicles.
Important considerations
- Avoid mixing: Never mix different coolant types, as it can cause corrosion and damage to your cooling system.
- Check the manual: Always consult your owner's manual to confirm the correct coolant type and specifications for your specific model year.
- Flush the system: Before changing coolants, thoroughly flush the old coolant from the system to prevent contamination.

How much coolant does a 6.7 hold?
The 6.7L engine coolant capacity varies by model year, but a 2017-2020 model typically has a primary cooling system capacity of around 31.7 to 35.1 quarts (303030 to 33.233.233.2 L). A secondary cooling system, if equipped, adds another 15.1 quarts (14.314.314.3 L). For 2011-2016 models, the capacity is around 29.4 to 30.3 quarts (27.827.827.8 to 28.728.728.7 L) for the primary system.
Primary cooling system
- 2017-2020: 31.7 to 35.1 quarts (303030 to 33.233.233.2 L)
- 2011-2016: 29.4 to 30.3 quarts (27.827.827.8 to 28.728.728.7 L)
Secondary cooling system (if applicable)
- 2017-2020: 15.1 quarts (14.314.314.3 L)
Note: These are approximate capacities. It is always best to check your specific vehicle's owner's manual for the exact capacity and recommendations.
