Key Features

Designed to meet and exceed OEM standards, the HPS Silicone Radiator Hoses Kit includes several advanced features that enhance both performance and longevity:

• Premium-grade, 3-ply reinforced silicone construction for exceptional heat resistance and durability
• Engineered with accurate bends and curves for a perfect, hassle-free fitment on the Jeep Grand Cherokee 4.0L I6
• Includes 100% stainless steel, non-perforated embossed hose clamps that secure hoses without damaging the silicone
• Rated for maximum temperatures up to 350°F, suitable for prolonged exposure to engine and coolant heat
• Prevents coolant leaks and overheating caused by cracked, damaged, or collapsed OEM radiator hoses
• Race-proven design ensures long-lasting quality and reliability under high-stress conditions
• Compatible with both OEM and aftermarket cooling system components
• 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-heat resistant silicone reinforced with three layers of durable fabric, providing superior strength and flexibility compared to conventional rubber hoses. This multi-ply design allows the hoses to withstand extreme temperatures and pressures commonly found in automotive cooling systems. The silicone material resists cracking, swelling, and collapsing, which are typical failure modes of OEM rubber hoses over time.

Each hose is molded with precise bends and curves to match the factory routing on the Jeep Grand Cherokee 4.0L I6, ensuring a seamless installation without the need for modifications. The included stainless steel clamps are embossed and non-perforated, preventing damage to the hose surface while maintaining a secure seal.

Installation & Fitment

Installation of the HPS Silicone Radiator Hoses Kit is straightforward and designed to be a direct replacement for the factory hoses on 1999–2004 Jeep Grand Cherokee models with the 4.0L inline six-cylinder engine. No special tools or modifications are required, making it accessible for both professional mechanics and experienced DIY enthusiasts. The kit includes all necessary clamps to complete the installation, ensuring a tight, leak-free connection.

Proper installation will restore the integrity of the cooling system, reduce the risk of coolant leaks, and improve overall engine cooling efficiency.
