Construction & Design

The hoses in this kit are crafted from high-quality silicone reinforced with a 3-ply fabric layer, providing exceptional strength and flexibility. This construction allows the hoses to endure prolonged exposure to engine heat and coolant fluids without degrading or losing shape. The silicone material also offers improved resistance to ozone, UV rays, and chemical exposure compared to standard rubber hoses.

Each hose is precision-engineered with the exact bends and contours required for the Jeep Wrangler TJ’s cooling system, ensuring a seamless fit without the need for modifications. The included stainless steel clamps are designed to securely fasten the hoses while preventing damage to the silicone surface, promoting a leak-free seal and easy installation.

Installation & Fitment

Installation is straightforward, as the hoses are designed to be direct replacements for the factory radiator and heater hoses on 1997–2006 Jeep Wrangler TJ models with the 4.0L inline 6 engine. No cutting, trimming, or additional modifications are necessary, making this kit suitable for both professional mechanics and experienced DIY enthusiasts. The included stainless steel clamps simplify the installation process and ensure a secure, long-lasting connection.

It is recommended to regularly check coolant levels when using silicone hoses, as their water permeation rate is higher than standard EPDM rubber hoses. Routine maintenance will help maintain optimal cooling system performance.
