• Improves coolant flow reliability, reducing the risk of hose failure and engine overheating

Construction & Design

The PPE Lower Coolant Hose Kit is crafted from premium-grade silicone rubber that is 5mm thick and constructed with a 4-ply layered design. This multi-layer construction provides exceptional resistance to heat, pressure, and chemical exposure commonly encountered in engine bays. Unlike standard rubber hoses, the silicone material retains its flexibility over time, preventing cracking, hardening, and premature failure.

The included specialty worm drive clamps feature W-style inner liners that ensure even pressure distribution around the hose circumference, enhancing sealing performance and preventing leaks. Manufactured from stainless steel, these clamps resist moisture, road salts, and engine chemicals, significantly extending the lifespan of the entire cooling hose assembly.

Installation & Fitment

Installation of the PPE Lower Coolant Hose Kit is straightforward and designed for a direct replacement of the factory lower coolant hoses on 2003–2007 Dodge Ram 5.9L and 2007–2010 Dodge Ram 6.7L Cummins diesel engines. No cutting, trimming, or additional modifications are necessary. Simply remove the old hoses and clamps, then install the new silicone hoses using the supplied stainless steel clamps for a secure, leak-free fit.

This plug-and-play design allows for a quick and hassle-free upgrade that can be completed with basic hand tools, making it suitable for both professional mechanics and experienced DIY enthusiasts.
