Construction & Design

The upper coolant hose is crafted from premium silicone rubber featuring a 4-ply construction that provides multiple layers of reinforcement. This design enhances resistance to heat, pressure, abrasion, and chemical exposure, common challenges in diesel engine cooling systems. The 5mm thickness helps prevent common issues such as hose swelling, cracking, or collapsing over time, which are often seen with standard rubber hoses.

The included worm drive clamps utilize a unique W-style inner liner that evenly distributes clamping force around the hose circumference, ensuring a tight, leak-free seal. Manufactured from stainless steel, these clamps offer excellent corrosion resistance and maintain clamping strength even in harsh environments, contributing to the long-term durability of the cooling system.

Installation & Fitment

Installation of the PPE Upper Coolant Hose Kit is straightforward and designed as a direct replacement for the factory upper coolant hose on 1998.5 to 2002 Dodge Ram trucks with the 5.9L Cummins engine. No cutting, trimming, or additional modifications are required, making it an ideal upgrade for both DIY enthusiasts and professional mechanics. Simply remove the original hose and clamps, install the new silicone hose, and secure it with the supplied stainless steel clamps for a reliable, leak-free connection.
