Description
The Mishimoto MMHOSE-F250D-99RD is a red silicone coolant hose kit engineered specifically for the 7.3L Powerstroke, replacing the factory rubber hoses that are prone to rapid deterioration from years of heat, pressure, and abuse. Built with high-grade silicone reinforced by four layers of heat-resistant embedded fibers, this kit is designed to retain factory fitment while standing up to conditions that wear out stock rubber hoses over time.
Mishimoto’s approach to cooling system durability centers on materials that resist the heat cycling and pressure spikes a hard-working diesel truck generates. This silicone coolant hose kit carries a maximum temperature rating of 330°F, increases pressure tolerance, and is engineered for maximum durability and blowout prevention compared to aging factory rubber. It’s a straightforward upgrade for anyone looking to preserve the long-term reliability the 7.3L Powerstroke is known for, without altering the factory hose routing or fit.
