HPS Silicone Radiator and Heater Hose Kit

2008–2014 Scion iQ 1.3L 4-Cylinder

57-1341-BLUE

Overview:

The HPS Silicone Radiator and Heater Hose Kit is a direct replacement for the factory rubber hoses on your 2008 to 2014 Scion iQ 1.3L 4-cylinder. Designed to withstand the demanding conditions of both daily driving and competitive use, this kit ensures your engine cooling system operates at peak efficiency. By upgrading to premium blue silicone hoses, you reduce the risk of premature hose failure caused by cracking or splitting, which can lead to engine overheating and costly breakdowns.

Whether you’re a performance enthusiast or simply want to maintain reliable cooling system performance, this hose kit offers a durable and race-inspired solution that fits perfectly and performs reliably under high temperature and pressure conditions.

Key Features:

This HPS hose kit combines advanced materials and precise engineering to deliver superior durability and fitment:

• Constructed from high-temperature, 3-ply reinforced silicone for enhanced strength and longevity.
• Reinforced with premium polyester fabric to resist expansion under pressure and reduce risk of failure.
• Designed with exact bends and curves to match OEM hose routing for a hassle-free installation.
• Blue silicone finish provides a clean, race-inspired look under the hood.
• Capable of withstanding extreme heat and pressure typical of engine cooling systems.
• Improves cooling efficiency by maintaining consistent coolant flow without the degradation common in rubber hoses.
• Ideal for both spirited driving and daily commuting, ensuring reliable engine temperature management.
• Resistant to cracking, splitting, and aging compared to standard OEM rubber hoses.

Construction & Design:

The hoses in this kit are crafted from multi-ply premium-grade silicone, reinforced with high-quality polyester fibers. This construction provides superior resistance to heat, pressure, and chemical degradation compared to traditional EPDM rubber hoses. The silicone material also offers greater flexibility and durability, reducing the chance of leaks or bursts under demanding conditions.

Each hose is engineered with precise bends and lengths to perfectly replicate the original equipment fitment, making installation straightforward and eliminating the need for modifications. The vibrant blue color not only enhances engine bay aesthetics but also helps you quickly identify any potential leaks or issues during routine maintenance.

Installation & Fitment:

This hose kit is designed as a direct OEM replacement for the radiator and heater hoses on the Scion iQ 1.3L models from 2008 through 2014. The exact bends and curves ensure a perfect fit without the need for cutting, drilling, or special tuning. Installation uses existing factory mounting points and clamps, making it a straightforward upgrade for both professional mechanics and DIY enthusiasts.

• Direct bolt-on replacement for OEM radiator and heater hoses.
• No modifications or special tools required.
• Compatible with stock cooling system components.

What's Included:

• Complete set of radiator and heater hoses made from reinforced blue silicone.
• All necessary clamps and hardware for secure installation (if applicable).
• Installation instructions to guide proper replacement.

Ideal For:

This hose kit is perfect for Scion iQ owners who want to maintain or improve their vehicle’s cooling system reliability. It suits:

• Daily drivers seeking long-lasting, maintenance-free cooling hoses.
• Performance enthusiasts who demand durable components for spirited or track driving.
• Anyone replacing old, cracked, or leaking radiator and heater hoses to prevent overheating.

Maintenance Note

Because silicone hoses have a water permeation rate 10 to 15 times higher than standard EPDM rubber hoses, it is recommended to regularly check coolant levels when using this kit on daily-driven vehicles. This ensures optimal cooling system performance and prevents potential overheating issues.

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.
