What kind of coolant does a Lexus IS 250 take?
The Lexus IS 250 uses Toyota/Lexus long-life coolant, premixed 50/50 with distilled water. Use only OEM or equivalent coolant that meets Toyota/Lexus specifications.
The IS 250, built on the 2.5L V6 platform, requires a specific ethylene glycol-based long-life coolant designed for Toyota and Lexus engines. Using the correct formulation helps prevent corrosion, overheating, and cooling-system deposits in aluminum components. Always aim to match the exact spec from the owner’s manual or a dealership service bulletin, and avoid mixing unexpected coolant types.
Choosing the right coolant
These are the key characteristics to look for when selecting coolant for the IS 250. They help ensure compatibility with the engine and the cooling system’s materials.
- Premixed 50/50 coolant with distilled water, ready to pour
- Meets Toyota/Lexus Long-Life Coolant specifications (often sold as Toyota Genuine Long Life Coolant or an equivalent that carries the OEM spec)
- Phosphate-free and silicate-free formulation to protect aluminum engine components
- Color variation (pink/red or other) may occur by region; color alone is not a reliable indicator of compatibility
Using the correct specification is more important than the color you see in the bottle. If in doubt, verify the coolant meets the Toyota/Lexus Long-Life Coolant standard and is compatible with aluminum engines.
Maintenance: topping up and replacing coolant
When you top up or replace the IS 250’s coolant, follow these steps to ensure a proper fill and avoid damage to the cooling system.
- Ensure the engine and cooling system are completely cool before opening the radiator or reservoir cap.
- Open the reservoir cap (and radiator cap if applicable) slowly to relieve any residual pressure.
- Check the coolant level on the reservoir. If it’s below the MIN line, add the recommended 50/50 premixed coolant to the MAX level.
- Use only coolant that meets Toyota/Lexus Long-Life specifications; do not mix with unrelated coolants unless explicitly compatible.
- After topping up, run the engine to operating temperature with the radiator cap still off (carefully) to bleed air, then recheck levels and cap the system securely.
- Dispose of any old coolant at a proper recycling facility and avoid spills; never pour coolant down drains or onto soil.
If you’re performing a full coolant flush, it’s best to follow the service manual or have the procedure done at a dealership or reputable shop, as the IS 250 cooling system includes a radiator, thermostat, water pump, and heater core that require proper flushing and refilling procedures.
Where to buy the right coolant
To ensure you get the correct product, buy from sources that clearly state they meet Toyota/Lexus Long-Life Coolant specifications and are compatible with aluminum engines. Preferred options include Toyota Genuine Long Life Coolant or equivalents recommended by Toyota/Lexus dealers.
- Toyota Genuine Long Life Coolant (premixed 50/50)
- Equivalents that explicitly meet Toyota/Lexus Long-Life Coolant specifications
- At reputable auto parts stores or dealers, verify labeling and compatibility with the IS 250
When in doubt, confirm with a dealer or technician that the coolant you purchase meets the exact Toyota/Lexus specification for your vehicle’s model year and engine type.
Bottom line
For a Lexus IS 250, use Toyota/Lexus long-life coolant in a premixed 50/50 ratio with distilled water, ensuring the product meets the OEM specification for the vehicle. Do not mix different coolant types or use non-compatible products, and always consult the owner’s manual or a qualified technician for confirmation based on your specific model year.
Summary: The IS 250 requires a Toyota/Lexus long-life coolant that is premixed 50/50 with distilled water and meets the OEM specification. Use only compatible coolant, avoid mixing unknown formulas, and follow proper topping-up or replacement procedures as outlined by the manual or a service professional. Regular monitoring helps keep the cooling system reliable and the engine operating within its designed temperatures.
