Key Features

Engineered for durability and precision fitment, the HPS Silicone Radiator Hoses Kit offers several key advantages:

• Constructed from premium grade, high-heat resistant 3-ply reinforced silicone for superior strength and longevity
• Designed with exact bends and curves to match OEM specifications, ensuring a seamless fit without modifications
• Includes 100% stainless steel non-perforated embossed hose clamps that secure hoses firmly without damaging the silicone
• Prevents coolant leaks and engine overheating by replacing cracked, collapsed, or damaged OEM radiator hoses
• Race-proven design built to withstand extreme under-hood temperatures and prolonged exposure to coolant heat
• Maximum temperature rating of 350°F (177°C) for reliable performance in demanding environments
• Silicone material offers enhanced resistance to aging, cracking, and deformation compared to standard rubber hoses
• Recommended regular coolant level checks due to higher water permeation rate compared to EPDM rubber hoses

Construction & Design

The hoses are crafted from a high-quality 3-ply reinforced silicone compound that combines flexibility with exceptional heat and pressure resistance. This construction ensures the hoses maintain their shape and integrity even under extreme thermal cycling and mechanical stress. The silicone material resists cracking, swelling, and deterioration that commonly affect OEM rubber hoses over time.

Each hose is molded with precise bends and contours to replicate the factory hose routing, guaranteeing a direct bolt-on installation without the need for trimming or modification. The kit’s stainless steel clamps are designed to provide a secure, leak-free seal while protecting the hose surface from damage during tightening.

Installation & Fitment

Installation is straightforward and designed to be a direct replacement for the factory radiator hoses on Jeep Wrangler TJ models with the 2.5L inline-4 engine from 1997 through 2006. The hoses fit perfectly with no additional modifications required, making it suitable for both professional mechanics and DIY enthusiasts. The included stainless steel clamps simplify the installation process and ensure a durable, leak-free connection.

Regular inspection and maintenance of coolant levels are advised when using silicone hoses, as their water permeation rate is higher than standard rubber hoses. This helps maintain optimal cooling system performance and prevents overheating.
