Mishimoto Silicone Hose Kit Blue 2022+ Honda Civic 1.5T

Mishimoto Silicone Hose Kit Blue 2022+ Honda Civic 1.5T replaces OEM coolant plumbing with high-grade silicone hoses to deliver improved heat resistance and longer service life under daily and spirited driving.

Designed by Mishimoto as a direct replacement for the factory rubber hoses, this kit uses a combination of high-grade silicone and heat-resistant embedded fibers to provide a durable, flexible cooling system connection. The material composition resists aging, softening, and swelling compared to OEM rubber, maintaining consistent coolant routing and pressure containment.

• High-grade silicone construction — provides dimensional stability and flexibility across a wide temperature range, minimizing hose collapse and distortion during thermal cycling.
• Heat-resistant embedded fibers — reinforce each hose for improved abrasion resistance and long-term structural integrity under elevated under-hood temperatures.
• Direct-replacement fit — designed to match OEM hose geometry for straightforward installation without modification, preserving factory routing and clamp locations.
• Includes radiator and reservoir connections — replaces both upper and lower radiator hoses and the reservoir tank hoses to restore the full coolant circuit with matched silicone components.
• Blue finish — engine-bay visibility and corrosion-resistant exterior finish that resists oil and coolant staining.

Technical benefits

By replacing the factory rubber hoses with Mishimoto silicone hoses you reduce the risk of coolant leaks caused by age-related degradation. The reinforced construction maintains a reliable seal at hose-to-flange interfaces and helps preserve coolant pressure consistency during varying load and temperature conditions.

Application notes

Intended as a direct-fit replacement for the 2022+ Honda Civic equipped with the 1.5T engine. Installation follows standard coolant-system procedures: drain coolant, remove OEM hoses, install Mishimoto hoses with proper clamp torque, and refill and bleed the cooling system per manufacturer recommendations.
