What is the primary function of this heater hose?

This molded heater hose connects your vehicle's heater core to the heater tee fitting. Its main job is to allow hot coolant to flow through, which then heats the air that comes into your cabin for warmth.

What makes this a 'molded' heater hose?

A molded heater hose is shaped during manufacturing to match the specific bends and curves of the original factory hose. This ensures it fits precisely in your vehicle without needing to be forced or kinked, which can happen with universal straight hoses.

What material is this hose made from?

This Gates heater hose is constructed from a heat-resistant rubber compound. This material is chosen for its ability to withstand the high temperatures of engine coolant and resist degradation over time.

It's a direct replacement hose that fits a wide range of vehicles, including popular models like the 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy, and even older Dodge Chargers and Plymouth Horizons from the early 80s.

Made from a strong, heat-resistant rubber compound, this hose is built to handle the constant flow of hot coolant without cracking or degrading over time.
