Radiator Coolant Silicone Hose Kit for Dodge RAM 1500 2500 3500 (2009-2020) 5.7L

Reinforced Silicone Radiator Hose Kit for 2009-2020 Dodge, RAM Ram 1500, Ram 2500, Ram 3500, 1500, 2500, 3500 (5.7L Hemi / DS/DT/DJ/D2)

What it Does: Replaces failure-prone factory rubber cooling lines with 3-ply reinforced silicone to prevent coolant blowouts under extreme pressure, high ambient heat, and heavy towing loads.

The Stock Ram 1500, Ram 2500, Ram 3500, 1500, 2500, 3500 Cooling Weakness

Factory EPDM rubber radiator hoses degrade over time due to constant thermal cycling, internal pressure fluctuations, and extreme under-hood temperatures generated by the 5.7L V8 Hemi. As the OEM rubber dries out and loses its elasticity, it becomes highly susceptible to micro-cracking and sudden material fatigue. This deterioration inevitably leads to swelling and catastrophic hose ruptures at the connection points, particularly when the truck's cooling system is heavily stressed during high-payload hauling, prolonged idling, or steep inclines.

The Engineering Solution

This upgraded kit completely overhauls the critical coolant routing system utilizing heavy-duty, 3-ply silicone construction with a robust 4.5mm wall thickness. Unlike conventional rubber, this multi-layered silicone matrix maintains complete structural integrity across an aggressive working temperature range of -65°F to 500°F. Engineered to withstand a bursting pressure of 245 PSI and sustained working pressures of 0.3 to 0.9Mpa, these hoses will not balloon or expand under heavy engine load. This structural rigidity ensures consistent coolant volume and flow dynamics. Furthermore, the precise +/-0.5mm size tolerance guarantees a direct-fit, leak-free installation on the factory water pump and radiator inlet/outlets.
