2004–2007 Scion xB

57-1059-BLK / 57-1059-BLUE

Overview:

The HPS Silicone Radiator Coolant Hose Kit is a premium replacement for the stock rubber radiator hoses on 2004 to 2007 Scion xB models. Designed for both daily drivers and performance enthusiasts, this kit offers superior heat resistance and durability compared to OEM hoses. By upgrading to reinforced silicone hoses, you’ll reduce the risk of coolant leaks and engine overheating caused by cracked or collapsed factory hoses, ensuring reliable cooling system performance under demanding conditions.

Constructed to meet or exceed original equipment specifications, these hoses provide a long-lasting solution that withstands extreme temperatures and prolonged exposure to under-hood heat. This kit is ideal for anyone looking to maintain or improve their vehicle’s cooling system reliability with a high-quality, race-proven product.

Key Features:

This hose kit combines advanced materials and thoughtful design to deliver excellent performance and fitment.

• Made from high-temperature 3-ply reinforced silicone for maximum durability and heat resistance.
• Rated to withstand temperatures up to 350°F, exceeding OEM specifications.
• Precisely engineered with correct bends and curves to ensure a perfect fit on the Scion xB.
• Includes 100% stainless steel non-perforated embossed hose clamps that secure hoses without damaging the silicone.
• Prevents coolant leaks and engine overheating caused by aging or damaged OEM radiator hoses.
• Race-proven design built to endure prolonged exposure to coolant and under-hood heat.
• Available in multiple colors: Black, Blue, and Red to match your engine bay style.
• 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.

Construction & Design:

The hoses are constructed from reinforced silicone with a 3-ply design, providing exceptional strength and flexibility. This construction allows the hoses to resist cracking, collapsing, and deformation under high heat and pressure conditions typical of engine cooling systems. The kit’s hoses are molded with precise bends and curves to replicate the factory hose routing, ensuring straightforward installation and a secure fit without modifications.

The included stainless steel clamps are non-perforated and embossed, which prevents cutting or damaging the silicone material during installation and use. This attention to detail enhances the longevity and reliability of the cooling system components.

Installation & Fitment:

This kit is designed as a direct replacement for the OEM lower and upper radiator coolant hoses on 2004–2007 Scion xB models. Installation is straightforward and requires no cutting, drilling, or special tuning. The hoses fit precisely using existing mounting points and connections, making it an ideal upgrade for both maintenance and performance enhancement.

• Direct bolt-on replacement for OEM radiator hoses.
