What coolant does a Toyota 86 use?
The Toyota 86 uses Toyota Genuine Long Life Coolant (pink, OAT). You can also use other OAT-based coolants that meet Toyota specifications, but avoid silicate-containing formulas.
In this article, we explain the recommended coolant options, how to identify a compatible product, and practical steps for filling, flushing, and maintaining the 86’s cooling system.
Coolant options for the 86
Note: The 86’s cooling system requires a silicate-free, ethylene glycol-based coolant. The following options align with Toyota’s guidelines and common service practices.
- Toyota Genuine Long Life Coolant (pink, OAT) — official Toyota-brand coolant recommended for most Toyota vehicles, including the 86. Use in a 50/50 mix with distilled water unless the label instructs otherwise.
- Other OAT-based coolants that meet Toyota specifications — look for products explicitly labeled as compatible with Toyota or meeting Toyota’s OAT requirements (silicate-free). These can be used if they state compatibility with Toyota vehicles.
- Avoid non-OAT or silicate-containing formulas — standard green antifreeze with silicates or universal coolants not explicitly approved for Toyota engines can cause corrosion or sealing issues over time.
In addition, for related models like the BRZ or FR-S, some owners use OEM-equivalent coolants that are cross-listed as compatible with Toyota’s OAT standards. Always verify compatibility with your vehicle’s manual or a dealer before mixing.
Bottom line: The safest option is Toyota Genuine Long Life Coolant, pink, OAT, or another OAT coolant explicitly labeled as Toyota-compatible. Color alone is not a reliable indicator of compatibility, so always check the product specifications.
Maintenance and replacement
To keep the cooling system in good condition, follow the manufacturer’s service schedule for coolant replacement. Typical intervals range from about 5 to 10 years or 100,000 to 120,000 miles, depending on driving conditions and climate. Always consult the owner’s manual for the exact interval and any model-specific notes.
- Park the car on level ground and allow the engine to cool completely before opening the radiator cap or reservoir.
- Place a drain pan beneath the radiator drain plug and open it to drain the old coolant fully.
- Flush the cooling system with distilled water or a dedicated flush product to remove debris and contaminants.
- Close the drain, then refill with a 50/50 mix of distilled water and coolant (or the concentrate’s recommended ratio).
- Start the engine with the heater on high to help bleed air from the system, and top off the coolant as needed once the thermostat opens.
- Check for leaks and recheck the coolant level after the engine cools to confirm proper fill.
If you’re unsure about which product to use or how to bleed the system properly, consult a Toyota dealer or a qualified mechanic to avoid air locks or improper mixing.
Summary
The Toyota 86 should use Toyota Genuine Long Life Coolant (pink, OAT) or another OAT-based coolant explicitly approved for Toyota vehicles. Avoid silicate-containing green formulas and non-approved products. Follow the owner’s manual for the correct mixing ratio and replacement interval, and seek professional guidance if you’re unsure.
