What coolant does Toyota dealership use?
Toyota dealerships typically use Toyota Genuine Long Life Coolant (LLC) or the newer Super Long Life Coolant (SLLC), depending on the model year and market. Both are OEM formulations designed for Toyota engines and are commonly sold premixed in a 50/50 blend. Always check your owner's manual and confirm with the service advisor before service.
Understanding Toyota's coolant lineup
Toyota categorizes its official coolant offerings into LLC and SLLC. The exact choice depends on your vehicle’s age, engine design, and regional guidelines. At service, dealerships will use the coolant specified for your VIN, ensuring compatibility with seals, gaskets, and cooling-system materials.
Below are the primary OEM coolant options you’ll see at a Toyota dealership.
- LLC — Long Life Coolant: a commonly used, silicate-free HOAT (hybrid organic/acid technology) coolant for many Toyota engines; typically sold premixed as a 50/50 blend and designed to protect against corrosion over extended service intervals.
- SLLC — Super Long Life Coolant: a newer formulation offering even longer service intervals and the same silicate-free HOAT base; often recommended for newer Toyota and Lexus engines and also sold premixed to simplify service procedures.
Dealers will generally use Toyota Genuine coolant products (LLC or SLLC) rather than aftermarket substitutes, following the manufacturer’s specification for your vehicle. They may provide a part-numbered receipt showing the exact product used.
How to confirm the right coolant for your vehicle
If you’re unsure which coolant your car requires or want to verify what a dealer will use, ask these questions before service:
- Which coolant is specified for my VIN and model year?
- Is the coolant premixed 50/50 or concentrated, and will there be a purge and refill?
- Are you using Toyota Genuine Long Life Coolant (LLC) or Super Long Life Coolant (SLLC)?
- Can you provide the product part number or a receipt showing the coolant used?
- Will the service include a coolant system check for leaks, contamination, or degraded hoses and seals?
Having explicit confirmation helps ensure compatibility, prevent cross-brand contamination, and protect your engine’s cooling system over the long term.
Summary
In short, Toyota dealerships generally rely on two OEM coolant formulations—LLC and SLLC—depending on the vehicle's age and market. Both are silicate-free, HOAT-based, and commonly sold premixed. To avoid surprises, verify the exact product for your car with the service advisor and request documentation showing the coolant used.
