How many gallons of coolant for a Toyota Tacoma?
In most cases, the Tacoma’s cooling system holds about 2 to 3 gallons of coolant when completely drained and refilled. The exact amount depends on the engine and model year: the 2.7-liter inline-four typically uses around 2.0 gallons, while the 4.0-liter V6 is closer to 3.0 gallons. For precise figures, consult your owner’s manual or the Toyota service literature for your specific truck.
Coolant capacity can vary slightly by year, trim, and cooling-system options. To ensure you use the correct amount, verify the specification for your exact vehicle before a drain-and-fill service.
By engine: typical cooling capacity for Toyota Tacoma
Engine choices in Tacoma models drive the total cooling-system size. The figures below reflect approximate full-system capacities commonly cited in Toyota manuals and service data.
- 2.7-liter inline-four (commonly used in many Tacomas): about 7.0 to 7.5 quarts (roughly 1.75 to 1.88 gallons).
- 4.0-liter V6 (the larger option found in older and some current trims): about 11 to 12 quarts (roughly 2.75 to 3.0 gallons).
The range above accounts for minor variations in radiator capacity, heater-core routing, and auxiliary cooling components across model years and specifications.
Why the numbers can vary
Seasonal updates, emission equipment, or optional cooling features can shift the exact capacity by a small amount. If your vehicle sits between production runs or has unique equipment, double-check the official specification for your VIN to avoid underfilling or overfilling.
How to verify the exact capacity for your truck
To confirm your Tacoma’s precise coolant capacity, use these steps. They help you lock in the correct figure from authoritative sources.
- Check the owner’s manual: Look in the specifications or maintenance section for “Cooling system capacity.”
- Consult the Toyota service manual or Tech Info system: Look up the coolant capacity by engine code or VIN.
- Call or visit a Toyota dealer: Provide your VIN and they can pull the exact specification for your truck.
- During a coolant service, follow the bleeding procedure in the manual and fill to the indicated capacity to ensure all air is purged.
Note: The goal is to reach the system’s rated capacity while ensuring no air pockets remain; follow the prescribed fill and bleed steps from the official manual.
Summary
The Toyota Tacoma does not have a single universal coolant capacity. Depending on the engine and year, you should expect roughly 2 to 3 gallons total—about 2.0 gallons for the 2.7L four-cylinder and about 3.0 gallons for the 4.0L V6. For the exact figure on your specific truck, reference the owner’s manual or the official Toyota service literature for your VIN.

How many gallons of antifreeze does a Toyota Tacoma take?
It is a little over 2 gallons if you can get all the old out. I've never had a 3.4 but I know some engines have a drain bolt or a bleeder that you can take off that gets it all or almost out when you flush out the coolant. Worth researching.
