HPS Silicone Radiator Hoses Kit

1994–2010 Dodge Ram 5.9L Diesel

Part #: 57-1222-BLK

Overview

The HPS Silicone Radiator Hoses Kit is a premium replacement solution designed specifically for Dodge Ram trucks equipped with the 5.9L diesel engine from 1994 through 2010. This kit offers a direct-fit upgrade over OEM and aftermarket rubber hoses, engineered to withstand the demanding conditions of diesel engine cooling systems. Ideal for enthusiasts and daily drivers alike, these hoses provide enhanced durability, heat resistance, and reliability to prevent common issues such as coolant leaks and overheating caused by aging or damaged factory hoses.

Whether you are restoring your Dodge Ram or seeking a long-lasting performance upgrade, this kit ensures optimal coolant flow and engine protection under high-temperature conditions, making it a smart investment for maintaining your truck’s cooling efficiency and longevity.

Key Features

Designed with precision and built to last, the HPS Silicone Radiator Hoses Kit offers several advantages over standard rubber hoses:

• Constructed from premium-grade, 3-ply reinforced silicone for superior heat resistance and durability
• Engineered with exact bends and curves for perfect OEM fitment and easy installation
• Includes 100% stainless steel, non-perforated embossed hose clamps that securely hold hoses without damaging the silicone
• Rated for maximum temperatures up to 350°F, suitable for prolonged exposure to under-hood heat and coolant temperatures
• Prevents coolant leaks and overheating issues caused by cracked, collapsed, or damaged OEM hoses
• Race-proven design ensuring long-lasting performance in demanding environments
• Compatible with 1994–2001 and 2002–2010 Dodge Ram models equipped with the 5.9L diesel engine
• Silicone material offers a water permeation rate 10 to 15 times greater than standard EPDM rubber hoses, so regular coolant level checks are recommended for daily-driven vehicles

Construction & Design

The hoses in this kit are crafted from high-quality silicone reinforced with three layers of durable fabric, providing exceptional resistance to heat, pressure, and aging. This multi-ply construction ensures the hoses maintain their shape and flexibility even under extreme thermal cycling and mechanical stress. The silicone material also resists cracking, collapsing, and deformation better than traditional rubber hoses, which can degrade quickly in diesel engine environments.

Each hose is molded with precise bends and contours to match the original factory routing, eliminating the need for modifications or adjustments during installation. The included stainless steel clamps are embossed and non-perforated, designed to secure the hoses firmly without cutting into the silicone, preserving hose integrity and preventing leaks.

Installation & Fitment

This kit is engineered for a direct bolt-on replacement of the upper and lower radiator hoses on Dodge Ram trucks with the 5.9L diesel engine from 1994 to 2010. Installation is straightforward and requires no special tools beyond standard hand tools. The hoses’ exact fitment and included clamps simplify the process, reducing installation time and effort.

Users should ensure the cooling system is properly drained before removing old hoses and follow standard safety precautions when working with coolant. Regular inspection of coolant levels is advised when using silicone hoses due to their higher water permeation rate compared to rubber.

What's Included

• Upper radiator hose (silicone, 3-ply reinforced)
• Lower radiator hose (silicone, 3-ply reinforced)
• Set of 100% stainless steel, non-perforated embossed hose clamps
• Installation instructions
