What coolant does a Lexus IS250 use?
The Lexus IS250 uses Toyota/Lexus Genuine Long-Life Coolant Type 2 (LLC Type 2), an ethylene glycol–based coolant designed for Toyota/Lexus engines. Top up with the same specification or an OEM-approved equivalent.
Coolant specification and compatibility
Understanding the exact specification helps ensure the cooling system remains protected from corrosion and overheating. The Type 2 designation refers to Toyota/Lexus’ long-life coolant formulation, which is typically mixed 50/50 with distilled water. It is commonly available as pre-mixed 50/50 or as concentrate to be mixed on site. Always check the label and your owner's manual for the exact requirement for your market and year.
Below are the main coolant options that meet Toyota/Lexus Type 2 compatibility:
- Toyota Genuine Long Life Coolant (LLC) Type 2 — ethylene glycol–based, silicate-free, designed for Toyota/Lexus engines; commonly sold as blue coolant and available as concentrate or pre-mixed 50/50.
- Toyota/Lexus Super Long Life Coolant (SLLC) — another branded family within the same long-life coolant line; ensures compatibility with Type 2 systems when labeled accordingly.
- OEM-approved equivalents that specify compatibility with Toyota/Lexus Type 2 coolant — look for labels stating "Type 2" or "Toyota/Lexus approved" on the container.
- Pre-mixed 50/50 coolant labeled for Toyota/Lexus Type 2 compatibility — convenient for topping up without separate water mixing.
Conclusion: Use the correct Type 2 coolant to maintain the IS250’s cooling system and avoid mixing incompatible formulas.
Maintenance and topping up guidelines
To keep the cooling system in good condition, follow these guidelines when topping up or replacing coolant:
- Always use coolant labeled for Toyota/Lexus Type 2 compatibility or Genuine LLC Type 2, and never mix with Dex-Cool or other non–Type 2 coolants.
- Mix coolant with distilled water to achieve the standard 50/50 concentration unless your manual specifies otherwise.
- If you are starting from a non-Type 2 coolant, perform a full cooling-system flush before refilling with Type 2 coolant.
- Prefer OEM or dealership-approved coolants to ensure proper corrosion protection for the IS250’s radiator, hoses, and water pump.
Signs your IS250 cooling system needs attention
Be alert for symptoms such as persistent overheating, visible coolant leaks, a sweet smell near the engine bay, rising temperature gauge, or unusually low coolant level. If any of these occur, stop driving and have the cooling system inspected by a qualified technician.
Where to buy and how to verify compatibility
Recommended sources include Lexus/Torsche dealerships, Toyota-certified service centers, and reputable automotive retailers. When shopping, verify that the product explicitly states compatibility with Toyota/Lexus Type 2 or LLC Type 2. Do not rely on color alone to judge compatibility, and consult the owner’s manual or a dealer if you are unsure.
- Check the packaging for “Type 2,” “LLC Type 2,” or “Toyota/Lexus approved” labeling.
- Use the IS250’s owner manual as the final reference for the exact spec and replacement intervals.
If you are unsure about the correct coolant for your specific IS250 year and market, contact a Lexus dealer or a qualified automotive technician for guidance.
Summary
The IS250 relies on Toyota/Lexus Long-Life Coolant Type 2 (LLC Type 2), an ethylene glycol–based, silicate-free coolant. Use OEM-approved Type 2 coolant (or pre-mixed 50/50 versions) and avoid mixing with non-Type 2 formulas. Maintain the system with proper 50/50 dilution using distilled water, follow the replacement interval recommended in your manual (typically around 5 years/100,000 miles for Type 2), and have the cooling system inspected if you notice overheating or leaks. Always verify compatibility with your exact year and market via the owner's manual or a Lexus dealer.
