How much coolant does a Lexus LS 460 hold?
The Lexus LS 460 cooling system holds roughly 11.0 to 12.0 quarts of coolant when filled to specification, which is about 10.5 to 11.5 liters. The exact amount can vary slightly by model year and whether you have the standard LS 460 or the LS 460L (long-wheelbase) version.
Capacity at a glance
Understanding the total capacity helps with planning purchases and maintenance. The figure below reflects the entire cooling circuit, including the radiator, engine block, heater core, hoses, and reservoir.
- Estimated total system capacity: about 11.0–12.0 quarts (10.5–11.5 liters)
Note: Exact capacity can vary by year and configuration, so always verify against the specific service data for your vehicle if precise numbers are required.
Model-year and variant considerations
Differences between the standard LS 460 and the LS 460L, as well as changes across model years, can affect the precise capacity due to variations in heater core size, expansion tank, and routing of hoses. In practice, the range above covers the typical full-system fill for most LS 460 models.
Practical guidance for filling and verification
When planning a coolant service, follow these steps to ensure the system is filled correctly and air is purged from the cooling passages.
- Park on level ground and ensure the engine is cold before opening any cooling system components.
- Use the recommended coolant type and mix (often a 50/50 premixed coolant, unless the manual specifies otherwise) and have enough to fill to the indicated level.
- With the radiator cap off (and heater on high if applicable), slowly fill the expansion tank to the specified mark, allowing air to escape as the coolant rises.
- Start the engine and monitor the level, watching for air pockets to bleed. Add coolant as needed until the system remains steady at the proper level with the engine at operating temperature and the cap removed.
- After the engine cools, recheck levels and top off if necessary to the recommended marks in the overflow reservoir.
Bleeding the system properly is essential to prevent air pockets that can cause hotspots or overheating. Always refer to the owner's manual or a Lexus service bulletin for the exact procedure and coolant specifications for your year.
Summary
The Lexus LS 460 typically requires about 11.0–12.0 quarts (10.5–11.5 liters) of coolant for a full, properly bled cooling system. While the basic figure covers most LS 460 and LS 460L configurations, exact capacity can vary by model year and hardware. Use the recommended coolant type and follow a careful bleeding procedure when servicing to ensure optimal cooling performance.
What kind of coolant does a Lexus ls460 take?
The recommended coolant for a Lexus LS460 is a pink or red, long-life, Hybrid Organic Acid Technology (HOAT) antifreeze, with specific products like the Prestone Asian Red or Pentofrost A4 being good options. It is crucial to use a coolant formulated for Asian vehicles, as mixing different types can damage the system. Always check your owner's manual for the most accurate information.
Recommended coolant type
- Color: Pink or red
- Chemistry: Long-life, Hybrid Organic Acid Technology (HOAT), silicate-free
- Form: Premixed is convenient, but a concentrate mixed with distilled water (50/5050 / 5050/50 ratio) also works
Specific product recommendations
- Prestone Asian Red Antifreeze+Coolant: This is a POAT (Phosphated Organic Acid Technology) coolant specifically formulated for Toyota and Lexus vehicles.
- Pentofrost A4: This is a phosphated OAT coolant that is categorized as HOAT and is suitable for Lexus vehicles.
- Toyota Super Long Life Coolant: This is the genuine OEM coolant and is a reliable option if you prefer to stick with the manufacturer's recommendation.
Important considerations
- Avoid mixing coolant types: Mixing different coolants can lead to corrosion, damage, and costly repairs. Always use a coolant specifically designed for Asian vehicles.
- Consult your owner's manual: Your owner's manual is the best source of information for the exact coolant type and replacement intervals.
