Key Features & Benefits

This hose basically carries hot engine coolant – that’s the fluid that keeps your engine from overheating – to your heater core. The heater core is like a little radiator inside your dashboard. The coolant warms it up, and then the blower fan pushes air across it, giving you heat inside the cabin. It’s a pretty simple system, but relies on these hoses doing their job. There's usually more than one, often an upper and a lower to create a loop. It’s part of your vehicle’s heating and cooling system, specifically the part that provides warmth to the interior. Think of it as a vital link connecting the engine’s warmth to where you are sitting. It's not directly involved in keeping the engine cool, but it utilizes the engine's heat.

Symptoms, Risks & Replacements

Well, if this hose fails, you’ll likely lose heat inside the car. You’ll notice if it’s a really bad leak – coolant will probably be dripping inside the vehicle, or you’ll see it under the hood. More subtly, a pinhole leak can cause a gradual loss of coolant, which can lead to overheating if you’re not careful. It acts like a shield, keeping the hot coolant where it needs to be and preventing it from spilling. They get old, they get brittle, and they crack, especially with temperature changes. Fixparts Online has a good selection of these, and replacing them is a relatively inexpensive way to avoid a bigger problem down the road.
