What material is this coolant hose made from?

This Gates coolant hose is constructed from EPDM (ethylene propylene diene monomer) rubber. This material is known for its good resistance to heat, ozone, and weathering, making it suitable for engine cooling systems.

Does this hose come with new clamps?

This product listing is for the molded coolant hose only. New hose clamps are not included and should be purchased separately if your existing ones are worn or damaged.

Why is a molded hose better than a universal cut-to-fit hose?

A molded hose is shaped specifically for your vehicle's application, ensuring it follows the exact routing without kinking or rubbing. This maintains proper coolant flow and makes installation more straightforward compared to a universal hose that requires cutting and fitting.

Product Details

This Gates molded coolant hose is built with EPDM rubber, the same material used in many original equipment hoses. It's specifically shaped to fit the lower radiator connection on your 1999-2003 Ford F-250 Super Duty with the 7.3L diesel engine. Because it's molded, it follows the exact bends and curves needed, ensuring a clean installation and preventing kinks that could restrict coolant flow.

A coolant hose might seem like a simple part, but it's crucial for keeping your engine from overheating. Over time, rubber hoses can become brittle, crack, or swell, leading to leaks and potential engine damage. This Gates hose is made to handle the heat and pressure cycles your diesel engine experiences, offering a solid replacement for a worn-out original.

When replacing your lower radiator hose, it's a good idea to inspect the upper hose and thermostat housing as well. Make sure you have fresh coolant on hand, and consider replacing the hose clamps if they show any signs of corrosion or weakness.
