Heater Hose on the 2017 Subaru Forester: What You Need to Know

The 2017 Subaru Forester, like many modern vehicles, is equipped with a heating system that relies on coolant circulation to provide warmth inside the cabin. A key component of this system is the heater hose, which plays an important role in transferring engine coolant from the engine block to the heater core and back again. So yes, the 2017 Subaru Forester does have heater hoses, and understanding their function, maintenance, and replacement is essential for keeping the vehicle's heating system running smoothly.

Heater hoses are flexible rubber tubes designed to carry hot coolant from the engine to the heater core, located behind the dashboard inside the cabin. The heater core acts like a small radiator that uses the hot coolant flowing through it to warm the air that eventually enters the cabin, heating it up. Without these heater hoses, coolant would not be able to circulate through the heater core, meaning no warm air would be available regardless of the temperature outside.

The heater hose on the 2017 Subaru Forester is typically made from sturdy rubber that can handle the heat and pressure of the engine coolant system. However, being made of rubber, the hoses are subject to wear and ageing over time. Exposure to heat, engine vibrations, and chemicals in the coolant can cause the hoses to become brittle, crack, or develop leaks. That's why keeping an eye on the condition of the heater hoses is a good idea as part of regular vehicle maintenance.

If a heater hose starts leaking or cracks, you might notice a few common symptoms in your Forester. The engine coolant level may drop, warning lights can appear on the dashboard, you might get less heat blowing from the vents or experience a damp carpet on the passenger side due to coolant leaking inside. In some cases, the engine can even overheat if coolant escapes and the system can't maintain the proper temperature.

When servicing the 2017 Subaru Forester, it's advisable to inspect the heater hoses visually. Look for any signs of cracks, soft spots, bulges, or leaks. Also check the hose connections where clamps keep the hose attached to the heater core and engine block. Loose or rusty clamps can lead to leaks and a drop in heating performance as well.

Replacement of heater hoses isn't a difficult task, but it does require some technical know-how. It's best to let a skilled mechanic handle it, particularly because the coolant system needs to be drained to avoid spillage and airlocks in the cooling system. When replacing hoses, new hose clamps should also be fitted to ensure a tight seal and prevent future leaks.

Here are some handy tips to keep in mind about heater hose maintenance for your 2017 Subaru Forester:

• Check the heater hoses whenever you do an oil change or coolant top-up to catch any early signs of damage.
• Replace heater hoses every 5 to 7 years, even if no leaks are apparent, as rubber compounds degrade with time.
• Use genuine or high-quality aftermarket hoses specifically designed for Subaru Forester models to ensure proper fit and durability.
• Keep an eye on coolant levels and look out for any sweet smell or puddles underneath the vehicle, which could indicate a leak.
• If you notice your heater isn't blowing warm air as it used to, don't ignore it, as it may be a sign that the heater hose or heater core needs attention.

Ultimately, heater hoses are small but vital parts of the heating system on a 2017 Subaru Forester. Ignoring these hoses can lead to heating failures in the cabin and potential engine overheating issues if coolant escapes. Routine inspection and replacement when needed help to ensure comfortable drives during colder seasons and maintain the overall health of the engine cooling system.

For Subaru Forester owners down under, especially those who enjoy a warm and cosy ride in winter or cool weather, keeping the heater hoses in good shape is an effortless way to avoid unexpected breakdowns and stay comfortable behind the wheel all year round.
