What Kind of Coolant Does the Toyota Tundra Use?

Before you begin, knowing what kind of coolant the Toyota Tundra uses is crucial. Toyota recommends using Super Long Life Coolant (SLLC), which is ethylene glycol-based and formulated specifically for Toyota engines. This coolant lasts up to 100,000 miles or ten years for the first replacement and every 50,000 miles or five years after that.

So, what kind of coolant does the Toyota Tundra use? Always use a genuine Toyota SLLC or an equivalent with similar specs. Mixing incompatible coolants can cause corrosion or damage to your cooling system.

What Color Coolant Does the Toyota Tundra Use?

You might be asking what color coolant the Toyota Tundra uses. For most models, including those from 2007 to 2025, Toyota’s SLLC is pink in color. This distinguishes it from the older red coolant used in earlier Toyota vehicles. Always double-check your owner’s manual to ensure compatibility with your model year.

If you’re still wondering what color coolant the Toyota Tundra uses, stick with pink Super Long Life Coolant to maintain consistency and avoid costly issues.

How to Change the Toyota Tundra Coolant: Step-by-Step Guide

Follow these steps carefully:

1. Ensure the engine is cool before starting. Never open a hot radiator cap.
2. Lift the vehicle using a jack if needed and locate the radiator drain plug underneath.
3. Place a drain pan under the radiator and open the plug to drain the old coolant.
4. Close the drain plug and fill the radiator and reservoir with the proper coolant mixture (typically 50/50 coolant and distilled water).
5. Start the engine and let it idle with the heat on high to bleed air from the system.
6. Top off the coolant if the level drops after the engine cycles.
