What does a heater hose do?

A heater hose circulates hot engine coolant to your vehicle's heater core. This process transfers heat from the coolant into the cabin, warming the interior of your car.

How do I know if I need to replace my heater hose?

Look for visible signs of damage like cracks, swelling, or leaks around the hose and its connections. If you notice coolant puddles under your car or a sweet smell from the engine bay, it's a good indicator that a hose might be failing.

Does this hose come with clamps?

This Gates heater hose part number 18665 does not include installation clamps. You will need to reuse your existing clamps or purchase new ones separately.
