Key Features

Engineered for durability and performance, the HPS Silicone Radiator & Heater Hoses Kit offers the following key benefits:

• Direct replacement or upgrade for OEM and aftermarket hoses with precise bends and curves for perfect fitment
• Constructed from premium-grade, 3-ply reinforced silicone for superior high-heat resistance
• Includes 100% stainless steel non-perforated embossed hose clamps that prevent damage to the silicone hoses during installation
• Designed to prevent coolant leaks and engine overheating caused by deteriorated factory hoses
• Race-proven design engineered for extremely high temperature service, with a maximum temperature rating of 350°F
• Long-lasting quality that withstands prolonged exposure to under-hood heat and coolant temperatures
• Compatible with daily driving and off-road use, providing enhanced reliability and peace of mind
• Note: Silicone hoses have a higher water permeation rate than standard EPDM rubber hoses; regular coolant level checks are recommended for daily-driven vehicles

Construction & Design

The hoses in this kit are crafted from high-quality silicone reinforced with three layers of durable fabric, ensuring exceptional strength and flexibility. This multi-ply construction allows the hoses to maintain shape and resist collapsing under vacuum or pressure, which is common in aging rubber hoses. The silicone material offers excellent resistance to heat, ozone, and chemicals found in automotive cooling systems, significantly extending the service life compared to OEM rubber hoses.

Each hose is molded with precise bends and contours to match the factory routing, eliminating the need for modifications during installation. The included stainless steel clamps are embossed and non-perforated, designed to secure the hoses firmly without cutting into the silicone, preventing premature failure and leaks.

Installation & Fitment

Installation is straightforward, as the hoses are designed to be a direct fit for the 2007–2018 Jeep Wrangler JK 3.8L V6 models. No cutting, trimming, or additional modifications are required. The kit replaces the lower and upper radiator hoses as well as the heater coolant hoses, restoring the integrity of the cooling system. The included stainless steel clamps simplify the installation process, ensuring a secure and leak-free connection.

Regular inspection of coolant levels is advised when using silicone hoses due to their higher water permeation rate compared to standard rubber hoses, especially for vehicles used in daily driving conditions.
