Technical Details and Construction

The Dorman 626-812 radiator coolant hose features a molded assembly construction that combines rubber and elastomer materials to withstand heat and pressure typical in cooling systems. Its black finish matches OEM specifications, while the hose’s multiple inside diameters (1.25", 1.78", and 0.72") accommodate various radiator and engine connections. The hose supports a maximum working pressure of 50 PSI and a maximum bend angle of 90 degrees, allowing it to fit precisely within the engine bay without kinking or collapsing. With a centerline length of 26.75 inches and two branches, this hose is designed to meet the specific routing requirements of Ram ProMaster 1500, 2500, and 3500 models.
