HKS 52008-AK004 Super Coolant Touring Pre-Diluted Long Life Antifreeze 4L

Vehicle Fitment

• Universal - compatible with all petrol and diesel vehicles using an ethylene glycol-based coolant system
• Suitable for turbocharged and naturally aspirated engines in performance, street, and touring applications
• Confirmed fitment includes: Subaru WRX (2002-2021), Subaru WRX STI (2004-2021), Subaru BRZ (2013-2020), Scion FR-S (2013-2016), Toyota 86 (2017-2020)

Fitment Notes

• Pre-diluted formula - ready to use straight from the bottle. Do not dilute further with water before adding to the cooling system.
• Compatible with aluminium, iron, brass, copper, and rubber cooling system components - verify compatibility with your specific cooling system materials before use.
• Recommended replacement interval: every 2-3 years for optimal rust and corrosion protection.
• Always flush the cooling system of old coolant before refilling with HKS Super Coolant Touring to prevent contamination and maintain the product's full performance characteristics.
• Not intended for use in racing applications requiring maximum cooling capacity - see HKS Super Coolant Racing (52008-AK002/AK003) for motorsport use.

Features

• Long-life coolant formulation - designed for extended service intervals of 2-3 years between changes, reducing maintenance frequency compared to conventional coolants.
• High anti-foaming performance - suppresses foam formation within the cooling system, which can reduce cooling efficiency and cause localised hot spots if left unchecked.
• Excellent rust and corrosion prevention - protects all cooling system metals including aluminium, iron, and copper alloys from oxidation and electrochemical corrosion over the full service interval.
• Freeze protection to -37°C (central value) - suitable for use in cold climates and provides a substantial safety margin below typical winter operating temperatures.
• Pre-diluted ready-to-use formula - ethylene glycol (40-50%) pre-mixed with pure water, eliminating the need to measure and mix concentrate on-site.
• Pink colour - easily distinguishable from other fluids for identification and system inspection purposes.
• All-round performance for safer touring - balanced formulation optimised for everyday street, spirited, and touring driving rather than dedicated motorsport use.

Product Description

The HKS 52008-AK004 Super Coolant Touring is a pre-diluted, long-life ethylene glycol antifreeze and coolant designed for all-round performance in street, spirited, and touring driving applications. Pre-mixed with pure water at a 40-50% ethylene glycol concentration, it is ready to pour directly into the cooling system without any on-site dilution or measurement - making cooling system maintenance straightforward and consistent. The formulation provides freeze protection down to -37°C (central value), making it suitable for use in cold climates while maintaining full corrosion and anti-foaming protection year-round.

HKS Super Coolant Touring is engineered with high anti-foaming characteristics and a comprehensive rust and corrosion inhibitor package that protects aluminium, iron, copper, and rubber cooling system components over a 2-3 year service interval. The pink colour makes it easy to identify and distinguish from other fluids during inspection and system maintenance. For motorsport and track applications where maximum cooling performance is required over corrosion protection longevity, HKS offers the Super Coolant Racing variants (52008-AK002/AK003). Always flush the cooling system before switching to HKS Super Coolant Touring to maintain the product's full performance properties.
