57-1336

Overview:

The HPS Silicone Radiator and Heater Coolant Hose Kit is a direct replacement upgrade for the stock rubber radiator and heater hoses on Subaru BRZ, Toyota 86, and Scion FR-S models within the specified years. Designed for both daily drivers and performance enthusiasts, this kit offers enhanced durability and heat resistance to help maintain optimal engine cooling under demanding conditions. By upgrading to high-quality silicone hoses, you’ll reduce the risk of coolant leaks and overheating caused by aging or damaged OEM hoses, ensuring reliable operation and peace of mind.

Built to meet or exceed original equipment specifications, the hoses withstand temperatures up to 350°F, making them ideal for prolonged exposure to under-hood heat and coolant temperatures. Whether you’re replacing worn components or seeking a more robust cooling system, this kit delivers a precise fit and long-lasting performance.

Key Features:

This hose kit combines advanced materials and thoughtful design to provide a superior cooling hose solution:

• Constructed from premium high-temperature 3-ply reinforced silicone for exceptional heat resistance and durability.
• Engineered with factory-correct bends and curves to ensure perfect fitment and easy installation without modifications.
• Includes 100% stainless steel non-perforated embossed hose clamps that securely fasten hoses without damaging the silicone.
• Designed to prevent coolant leaks and engine overheating caused by cracked, damaged, or collapsed OEM radiator and heater hoses.
• Race-proven design built to withstand extreme temperature conditions and prolonged exposure to engine bay heat.
• Maximum temperature rating of 350°F, exceeding typical OEM hose capabilities.
• Available in multiple colors including black, blue, and red to match your vehicle’s style or engine bay theme.
• Backed by a 2-year warranty for added confidence in quality and reliability.

Construction & Design:

The hoses are crafted from reinforced silicone, a material known for its superior resistance to heat, pressure, and aging compared to standard EPDM rubber hoses. The 3-ply reinforcement provides structural strength to resist collapsing or cracking under high temperature and pressure conditions. Each hose is precision-molded with the exact bends and contours required for a seamless OEM-style fit, eliminating the need for cutting or adjustments during installation.

The included stainless steel clamps are embossed and non-perforated, which prevents them from cutting into the silicone material, ensuring a secure and leak-free seal over time. This combination of materials and design choices results in a durable, long-lasting hose kit that performs reliably in both street and track environments.

Installation & Fitment:

This hose kit is designed as a direct replacement for the factory radiator and heater hoses on the following vehicles:

• Subaru BRZ (2013–2020)
• Toyota 86 (2017–2020)
• Scion FR-S (2013–2016)

Installation is straightforward and bolt-on, requiring no cutting, drilling, or special tuning. The hoses fit precisely using existing mounting points and connections, making it an ideal upgrade for both DIY enthusiasts and professional mechanics.

Note: Silicone hoses have a higher water permeation rate than standard rubber hoses, so it is recommended to regularly check coolant levels when used in daily driving applications.
