PPE Silicone Coolant Hose

2003–2012 Dodge Ram 5.9L & 6.7L Diesel

Part #: 213001077

Overview

The PPE Dual Fueler Coolant Hose is a premium replacement hose engineered specifically for Dodge Ram trucks equipped with 5.9L and 6.7L diesel engines from 2003 through 2012. Designed to meet the rigorous demands of heavy-duty applications, this silicone coolant hose offers enhanced durability and reliability over standard rubber hoses. Whether you are towing heavy loads, competing in motorsports like drag racing or sled pulling, or simply upgrading your daily driver’s cooling system, this hose provides consistent performance under extreme temperatures and pressures.

Built to resist fuel, oil, chemicals, UV rays, and ozone exposure, the PPE silicone hose maintains its integrity in harsh environments, preventing common failures such as blowouts and leaks. This makes it an ideal upgrade for enthusiasts and professionals who require dependable cooling system components for their Dodge Ram diesel trucks.

Key Features

Engineered for maximum strength and longevity, the PPE Dual Fueler Coolant Hose incorporates advanced materials and design elements to ensure superior performance:

• Constructed with 5 plies of Nomex reinforced fibers for exceptional tensile strength and durability
• Fluorocarbon inner lining offers excellent lubricity and chemical resistance to extend hose life
• Silicone rubber exterior withstands extreme temperatures from -76°F to +437°F
• Maintains structural integrity under high boost pressures without risk of blowout
• Resistant to fuel, oil, and harsh chemicals commonly encountered in diesel engine environments
• UV and ozone resistant to prevent degradation from environmental exposure
• Inner diameter of 1.75 inches with a robust 6mm wall thickness for optimal flow and durability
• Requires hose clamps sized 1/2 inch larger than hose ID for proper secure fitment

Construction & Design

The PPE Dual Fueler Coolant Hose is meticulously crafted using premium materials to deliver long-lasting performance under demanding conditions. At its core, a fluorocarbon lining reduces friction and resists chemical attack from fuels and oils, significantly extending the hose’s service life. Surrounding this lining are five layers of Nomex reinforced fibers, a high-strength, heat-resistant material that provides structural support and prevents deformation under pressure.

The outer layer is made of durable silicone rubber, offering excellent flexibility and resilience to withstand extreme temperature fluctuations—from sub-zero cold starts to intense engine heat. This multi-layer construction ensures the hose can reliably handle the high boost pressures and thermal stresses typical of performance and heavy-duty diesel applications.

Installation & Fitment

Installation of the PPE Dual Fueler Coolant Hose is straightforward for anyone familiar with automotive cooling systems. It is designed as a direct-fit replacement for Dodge Ram models from 2003 to 2012, including the 5.9L diesel trucks from 2003–2009 and the 6.7L diesel trucks from 2010–2012 (Ram 2500 and 3500). No modifications are necessary for proper installation.

Due to the hose’s 6mm wall thickness, it is important to use hose clamps that are 1/2 inch larger in diameter than the hose’s 1.75-inch inner diameter to ensure a secure, leak-free connection. This attention to fitment detail guarantees reliable operation even under high-stress conditions.
