Part #: 57-1590-BLK

Overview

The HPS Silicone Heater Hoses Kit is a premium replacement solution designed specifically for Jeep Wrangler models equipped with the 2.5L inline-4 engine from 1997 through 2006. This kit addresses common issues associated with aging or damaged OEM heater hoses, such as coolant leaks and engine overheating. Crafted for both daily drivers and off-road enthusiasts, it offers enhanced durability and reliability under extreme temperature conditions, ensuring your vehicle’s heating system performs optimally.

Whether you are restoring your Jeep or upgrading from standard rubber hoses, this kit provides a direct-fit, long-lasting alternative that resists cracking, collapsing, and heat degradation. It is ideal for those seeking to maintain or improve their vehicle’s cooling system integrity with a high-quality, race-proven component.

Key Features

Engineered for durability and perfect fitment, the HPS Silicone Heater Hoses Kit offers several advantages over standard OEM or aftermarket hoses:

• Constructed from premium-grade, high-heat resistant 3-ply reinforced silicone for superior strength and flexibility.
• Designed with precise bends and curves to ensure a perfect, OEM-style fit without modifications.
• Includes 100% stainless steel non-perforated embossed hose clamps that prevent hose damage and simplify installation.
• Resistant to cracking, collapsing, and coolant leaks that commonly affect rubber hoses over time.
• Race-proven design engineered to withstand prolonged exposure to under-hood heat and coolant temperatures up to 350°F.
• Helps prevent engine overheating by maintaining reliable coolant flow through the heater core.
• Compatible with both OEM and aftermarket cooling system components for versatile use.
• Recommended for use in daily driven vehicles with regular coolant level checks due to silicone’s higher water permeation rate compared to EPDM rubber.

Construction & Design

The hoses in this kit are manufactured using a three-layer reinforced silicone compound that combines flexibility with exceptional heat resistance. This construction ensures the hoses maintain their shape and integrity even under extreme thermal cycling and pressure conditions typical in automotive cooling systems. The silicone material also resists oil, chemicals, and environmental degradation better than standard rubber hoses.

Each hose is molded with exact bends and curves matching the original factory specifications, allowing for a seamless installation without the need for trimming or adjustments. The included stainless steel clamps are embossed and non-perforated, which prevents cutting into the hose surface, extending the lifespan of the connection points and ensuring a secure, leak-free seal.

Installation & Fitment

The HPS Silicone Heater Hoses Kit is designed for a direct bolt-on replacement for Jeep Wrangler 2.5L I4 models from 1997 to 2006. Installation is straightforward and requires no special tools beyond standard hand tools. The kit’s precise fitment eliminates the need for modifications or custom adjustments, making it suitable for both professional mechanics and experienced DIY enthusiasts.

For optimal performance and longevity, it is recommended to inspect and maintain coolant levels regularly, especially when using silicone hoses, due to their higher water permeation rate compared to traditional rubber hoses.

What's Included

• Set of high-heat resistant 3-ply reinforced silicone heater hoses with OEM-correct bends
