Key Features

Designed with precision and durability in mind, the HPS Silicone Radiator Hoses Kit offers the following key benefits:

• Premium-grade, high-heat resistant 3-ply reinforced silicone construction
• Correct bends and curves for perfect OEM-style fitment
• Includes 100% stainless steel non-perforated embossed hose clamps that prevent hose damage during installation
• Prevents coolant leaks and overheating caused by deteriorated OEM radiator hoses
• Race-proven design engineered for prolonged exposure to under-hood heat and coolant temperatures
• Maximum temperature rating of 350°F (177°C) for reliable high-temperature service
• Significantly lower risk of hose collapse or cracking compared to standard rubber hoses
• Recommended regular coolant level checks due to silicone’s higher water permeation rate compared to EPDM rubber

Construction & Design

The hoses are crafted from a high-quality, 3-ply reinforced silicone material that offers superior heat resistance and flexibility compared to traditional rubber hoses. This multi-layer construction ensures durability against cracking, swelling, and collapsing, even after prolonged exposure to engine heat and coolant chemicals. The silicone material also resists oil, chemicals, and ozone, extending the service life of the hoses.

Each hose is molded with precise bends and curves to match the original equipment specifications, guaranteeing a seamless fit without the need for modifications. The included stainless steel clamps are non-perforated and embossed, designed to secure the hoses firmly without cutting into the silicone, ensuring a leak-free seal and easy installation.

Installation & Fitment

This kit is engineered for a direct bolt-on replacement for the 2000–2006 Jeep Wrangler TJ 4.0L I6 models. Installation requires no special tools or modifications, making it accessible for both professional mechanics and experienced DIY enthusiasts. The included stainless steel clamps simplify the installation process by providing a secure and damage-free connection.

It is important to regularly check coolant levels when using silicone hoses in daily-driven vehicles, as silicone has a higher water permeation rate than standard EPDM rubber hoses. Routine maintenance will help ensure optimal cooling system performance and longevity.

What's Included

• Upper and lower radiator silicone hoses molded for perfect fitment
• 100% stainless steel non-perforated embossed hose clamps for secure installation
