57-1725-RED

Overview:

The HPS Reinforced Silicone Radiator Hose Kit is a complete set of high-temperature, 3-ply reinforced silicone hoses designed specifically for the 2016 Scion iM 1.8L. This kit replaces the factory OEM rubber radiator hoses, bypass coolant hoses, and expansion tank hoses with durable, heat-resistant silicone components that meet or exceed original equipment specifications.

Ideal for daily drivers and performance enthusiasts alike, this hose kit offers enhanced reliability and longevity under extreme under-hood temperatures. You’ll benefit from improved durability and peace of mind knowing your cooling system components are built to withstand prolonged exposure to heat and coolant.

Key Features:

This hose kit combines advanced materials and precise engineering to deliver superior performance and fitment for your Scion iM.

• Constructed from premium-grade, high-heat resistant 3-ply reinforced silicone for long-lasting durability over OEM rubber hoses.
• Designed with correct bends and curves to ensure a perfect, direct fitment without modifications.
• Replaces all critical coolant hoses including upper and lower radiator hoses, bypass coolant hoses, and expansion tank hoses.
• Includes 100% stainless steel non-perforated embossed hose clamps that provide secure installation without damaging the silicone hoses.
• Maximum temperature rating of 350°F, ideal for extreme temperature service and prolonged exposure to under-hood heat.
• Backed by HPS Performance Products’ limited lifetime warranty for added confidence and quality assurance.

Construction & Design:

The hoses are engineered with a reinforced 3-ply silicone construction that combines flexibility with strength. This design resists cracking, swelling, and deterioration common in OEM rubber hoses exposed to heat and coolant over time. The silicone material also offers superior resistance to heat and pressure, ensuring consistent coolant flow and system reliability.

Each hose is molded with precise bends and curves to match the factory routing, allowing for a seamless installation that maintains proper coolant flow without kinks or restrictions. The included stainless steel clamps are embossed and non-perforated to prevent cutting or damaging the silicone, ensuring a secure and leak-free connection.

Installation & Fitment:

This hose kit is a direct replacement for the 2016 Scion iM 1.8L’s stock radiator and coolant hoses. It installs easily using existing mounting points and requires no cutting, drilling, or special tuning. The kit includes all necessary clamps for a complete installation, making it a straightforward upgrade for both professional mechanics and knowledgeable enthusiasts.

• Direct bolt-on replacement for OEM rubber hoses
• No modifications or special tools required
• Includes stainless steel clamps for secure fitment

What’s Included

• Seven-piece reinforced silicone hose set covering radiator upper and lower hoses, bypass coolant hoses, and expansion tank hoses
• 100% stainless steel non-perforated embossed hose clamps for all hoses

Ideal For:

• Daily drivers seeking improved cooling system reliability and longevity
• Performance enthusiasts who demand high-heat resistance under spirited driving conditions
• Anyone looking to replace aging or deteriorated OEM rubber coolant hoses with a durable silicone alternative

Important Note

Silicone hoses have a water permeation rate 10 to 15 times greater than standard EPDM rubber hoses. It is highly recommended to regularly check coolant levels when using silicone hoses in daily driven vehicles to maintain optimal cooling system performance.

HPS Performance specializes in high-temperature reinforced silicone hoses and related joining solutions—couplers, tubing, and clamps—built for boosted and high-heat engine bays. Used in performance and racing applications, HPS products are designed to meet demanding temperature and pressure conditions for dependable charge-air and coolant routing.
