HKS 52008-AK003 Super Coolant Sport 4L Pre-Diluted -18 DegC Non-Amine Made Japan

Vehicle Fitment

• Universal - compatible with all gasoline engine cooling systems

Fitment Notes

• This is a straight type (pre-diluted) coolant - it is supplied at the correct concentration for direct use and must NOT be diluted further with water before filling; adding water after purchase will reduce freeze protection and cooling performance below the rated specification
• Verify your vehicle's cooling system capacity before ordering; 4 liters covers most 4-cylinder applications but larger displacement engines may require additional volume
• Compatible with all common cooling system metals including copper, steel, solder, cast iron, brass, and aluminum - safe for use in both older all-metal systems and modern aluminum-intensive cooling systems without supplemental corrosion inhibitor additives
• As a non-amine formula, this coolant is safe for use in all standard automotive rubber and elastomer cooling system components - amine-based coolants can cause degradation in some hose and seal materials over time; this product does not carry that risk
• Recommended replacement interval is 2-3 years - HKS recommends periodic replacement regardless of appearance, as coolant additives deplete over time even if the fluid color and clarity appear acceptable
• Do not mix with other coolants or antifreeze products - mixing may compromise the non-amine formula, corrosion inhibitor package, or freeze protection; flush the cooling system before switching from a different coolant brand or type

Features

• Pre-diluted straight type - the coolant is supplied ready to use at the correct water-to-glycol ratio; installation requires only draining the existing coolant, flushing if switching from a different product, and filling directly from the bottle with no measuring, mixing, or dilution step required
• Freeze protection to -18°C / -4°F - the rated freeze point provides protection appropriate for most street driving environments; this is calibrated for the Sport grade's target use case of sporty street and road driving rather than the extended cold-weather extreme tolerance of some concentrated formulas
• Non-amine (amine-free) formula - all three variants in the HKS Super Coolant range are formulated without amine compounds, which can degrade certain cooling system seals and hoses over extended contact, and which are restricted or regulated in some waste water disposal contexts; the non-amine formula is both safer for cooling system components and easier to dispose of responsibly
• Full corrosion protection for all common cooling system metals - copper, steel, solder, cast iron, brass, and aluminum cast iron are all covered by the corrosion inhibitor package, making this compatible with the full spectrum of engine and cooling system materials found in performance vehicles from the 1980s through current production
• Sport tier positioning in HKS's three-product Super Coolant lineup - sits between the Racing Pro (track-focused, maximum anti-foaming and protection, oriented toward motorsport use) and the Touring (broadest everyday all-round use); Sport is optimized for enthusiast street driving including spirited road use, mountain passes, and extended high-load driving conditions that exceed typical commuting demands but do not require full track-grade formulation
• Made in Japan - consistent with HKS's fluid product line; the manufacturing location is noted on HKS's own product pages as a quality differentiator
• 2-3 year replacement interval provides a clear and practical service schedule - shorter than the extended-life intervals of some OEM coolants, reflecting the performance-oriented formulation's design priority on protection and cooling properties over maximizing service life

Product Description

The HKS 52008-AK003 is the Super Coolant Sport in the 4-liter size - the middle tier in HKS's three-product Super Coolant range, positioned between the Racing Pro (track-focused, maximum anti-foaming and protection) and the Touring (all-round everyday use). Its tagline is "For More Comfortable Sporty Driving!" and it is formulated for the use case of enthusiast street driving: spirited road use, canyon and mountain driving, and extended high-load conditions that go beyond typical daily commuting without requiring the full specification of a dedicated motorsport coolant.

This is a straight type (pre-diluted) coolant - it is supplied at the correct concentration for direct use and is poured into the cooling system without any additional dilution. The rated freeze point is -18°C / -4°F. The non-amine formula is safe for all standard rubber and elastomer cooling system components and is compatible with all common cooling system metals including copper, steel, solder, cast iron, brass, and aluminum - covering both older all-metal cooling systems and modern aluminum-intensive designs. The same corrosion coverage and non-amine formulation applies across all three Super Coolant grades. Made in Japan. Recommended replacement interval is 2-3 years.

When selecting between the three Super Coolant grades: Racing Pro is appropriate for dedicated track use and motorsport applications requiring maximum anti-foaming performance and the highest cooling efficiency; Sport covers the full range of performance street use from daily driving through aggressive road driving; Touring is suited to all-round everyday use where cooling demands are modest. All three types are pre-diluted, non-amine, and made in Japan.
