What is a bypass heater hose?

A bypass heater hose is part of your vehicle's cooling system that circulates coolant through the heater core. This hose specifically handles the coolant flow that bypasses the main engine block to reach the heater core, allowing your cabin to get warm.

What material is this heater hose made from?

This heater hose is constructed from a heat-resistant rubber compound, which is standard for components in the high-temperature environment of an engine's cooling system.

Does this hose come with clamps?

This Gates molded heater hose does not include installation clamps. You will need to use your existing clamps or purchase new ones separately to secure the hose.
