Product Details

Tired of dealing with brittle, dry-rotted rubber hoses? Whether you're refreshing your cooling system or replacing aging components, this ECS Silicone Radiator Coolant Hose Set is the ultimate upgrade. Designed for durability, performance, and a factory-perfect fit, these premium silicone hoses outperform standard rubber in every way.

Why Choose Silicone Over Rubber?

Made from heavy-duty, reinforced 4-ply fluorosilicone, ECS hoses withstand extreme temperatures and pressures far beyond OEM rubber hoses. Engineered to resist oil, fuel, and electrochemical degradation, these hoses are tested for continuous operation at 250°F and over 45 psi, delivering superior reliability, reduced turbulence, and improved coolant flow.

Key Benefits:

Direct OE Fitment – Perfectly molded to factory specifications for seamless installation.
Enhanced Durability – Heat-resistant silicone prevents cracking, swelling, and deterioration over time.
Superior Cooling Performance – Smoother internal passageways improve coolant flow and system efficiency.
Premium Hardware Included – Comes with German-style stainless steel worm-drive hose clamps for a secure fit.

Kit Includes:

Upper Radiator Hose
Lower Radiator Hose
Stainless Steel Worm-Drive Hose Clamps (4)

Replaces OEM Part Numbers: 17127599450 & 17127540127. Can be used with your factory connectors.
