What kind of coolant does a 2004 LS430 take?
The 2004 Lexus LS430 uses Toyota/Lexus Long-Life Coolant (LLC). For best results, use the official 50/50 premixed formula or a concentrate that you mix with distilled water, and avoid non-Toyota formulas unless they are explicitly approved for Toyota/Lexus LLC.
Approved coolant options
The following coolant options are commonly used for this model when they meet Toyota's Long-Life Coolant specification. Always verify that the product states compatibility with Toyota/Lexus Long-Life Coolant.
- Toyota Genuine Long-Life Coolant (LLC), premixed 50/50 with distilled water, typically blue or blue-green in color.
- Toyota Genuine Long-Life Coolant Concentrate, to be mixed 1:1 with distilled water to yield a 50/50 coolant.
When in doubt, refer to the owner's manual or a Toyota/Lexus dealer for the exact specification and approved product; using an unapproved coolant can void warranties or lead to cooling system damage.
Mixing, replacement, and maintenance guidelines
For proper maintenance, always use distilled water to mix any concentrate and ensure the system is within the recommended 50/50 ratio. Do not mix with tap water or other coolant types unless they are proven to meet Toyota's LLC specification. Perform a drain-and-fill as part of regular service intervals or when replacing a leaking hose or radiator cap.
To refill or flush the cooling system, follow these steps:
- Ensure the engine is completely cool before opening the radiator cap or pressure caps on the reservoir.
- Place the car on a level surface and drain the old coolant from the radiator and engine block, following the service manual for the LS430.
- Rinse with distilled water to remove residual contaminants, then drain again.
- Fill with the 50/50 mix of distilled water and the chosen coolant (premixed LLC counts as the premixed 50/50), until the reservoir is at the correct level.
- Run the engine with the heater on high to circulate coolant, top off as needed after the air bleeds from the system.
- Check for leaks and confirm the temperature gauge remains within normal range after test driving.
Following the correct mixture and procedure helps ensure the LS430's cooling system remains corrosion-free and operates efficiently for the long term.

Color differences and labeling
