What does this hose connect?

This molded heater hose connects your vehicle's heater core to the engine's cooling system. It allows hot coolant to flow through the heater core, which then heats the air blown into the cabin.

What makes this a 'molded' hose?

A molded hose is shaped during manufacturing to match the specific routing and bends required for your vehicle's engine bay. This ensures a precise fit and helps prevent kinks or restrictions in coolant flow.

What other parts should I check when replacing a heater hose?

When replacing a heater hose, it's a good time to inspect your other cooling system components. Check the condition of your radiator hoses, thermostat, water pump, and coolant for any signs of leaks or wear.

Product Details

When the cold weather hits and your truck's heater isn't blowing warm air, a faulty heater hose is often the culprit. This molded heater hose from Gates is specifically made for your 1999-2003 Ford F-250 Super Duty with the 7.3L diesel engine, connecting the heater core to the engine's cooling system to circulate hot coolant. Keeping this hose in good condition is key to maintaining cabin comfort during those chilly months.

Gates uses a durable rubber compound that resists heat and coolant degradation, so you can expect it to hold up under the hood. This hose is molded to the exact shape needed for your Super Duty, meaning it should fit right without a struggle, making the replacement process smoother. Proper fitment is important for heater hoses to prevent kinks and ensure unrestricted coolant flow, which is crucial for effective cabin heating.

Replacing a heater hose is a common maintenance task, especially on older diesel trucks. Make sure to check your other cooling system components while you're in there, like the thermostat and radiator hoses, to ensure everything is in top shape.
