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 maintain their shape and integrity even under prolonged exposure to high temperatures and harsh engine bay conditions. The silicone material also resists cracking, swelling, and deterioration common with traditional EPDM rubber hoses.

Each hose is precision-molded with the exact bends and curves required for a seamless fit on the Jeep Wrangler TJ 4.0L I6, eliminating the need for modifications or adjustments during installation. The included stainless steel clamps are embossed and non-perforated, preventing damage to the hose surface and ensuring a leak-free seal.

Installation & Fitment

The HPS Silicone Heater Hoses Kit is designed for straightforward installation with direct-fit hoses and all necessary clamps included. No special tools or modifications are required, making it an ideal upgrade for both professional mechanics and DIY enthusiasts. The kit fits all 1997–2006 Jeep Wrangler TJ models equipped with the 4.0L inline 6-cylinder engine, ensuring compatibility and ease of replacement.

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