Overview:

The HPS Silicone Radiator and Heater Coolant Hose Kit is a direct replacement for the factory rubber radiator and heater hoses on select Scion FR-S, Subaru BRZ, and Toyota 86 models. Designed for both daily drivers and performance enthusiasts, this kit offers enhanced durability and heat resistance to help prevent coolant leaks and overheating issues caused by aging or damaged OEM hoses. With its high-temperature silicone construction, you’ll get reliable performance and long-lasting quality under demanding engine bay conditions.

This kit is ideal for those looking to upgrade their cooling system components with premium materials that meet or exceed original equipment specifications, ensuring a perfect fit and dependable operation.

Key Features:

Engineered for durability and heat resistance, this hose kit offers several advantages over standard rubber hoses:

• Constructed from high-temperature 3-ply reinforced silicone, rated for up to 350°F to withstand extreme under-hood heat.
• Precisely molded with correct bends and curves for an exact fit on Scion FR-S (2013–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020).
• Includes 100% stainless steel non-perforated embossed hose clamps that provide secure installation without damaging the silicone hoses.
• Designed to prevent coolant leaks and engine overheating caused by cracked, collapsed, or deteriorated OEM radiator and heater hoses.
• Race-proven design offering long-lasting quality and resistance to prolonged exposure to coolant and engine heat.
• Available in multiple colors including black, blue, and red to match your engine bay aesthetic.
• Silicone hoses have a water permeation rate 10 to 15 times greater than standard EPDM rubber hoses; regular coolant level checks are recommended for daily driving applications.

Construction & Design:

This hose kit features premium-grade silicone material reinforced with a 3-ply construction for superior strength and flexibility. The hoses are designed to maintain shape and integrity under high temperatures and pressure, reducing the risk of cracking or collapsing over time. The stainless steel clamps are embossed and non-perforated, ensuring they securely fasten the hoses without cutting into the silicone, which enhances durability and leak prevention.

The kit’s precise bends and curves are engineered to match the OEM hose routing, allowing for straightforward installation without modification. This thoughtful design helps maintain proper coolant flow and system efficiency.

Installation & Fitment:

This kit is a direct bolt-on replacement for the factory radiator and heater hoses on the following vehicles:

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

No cutting, drilling, or special tuning is required for installation. The kit uses factory mounting points and includes all necessary clamps for a secure fit. It is recommended to regularly check coolant levels when using silicone hoses due to their higher water permeation rate compared to rubber.
