Parts for your 2017 Subaru Forester-Coolant

Understanding Coolant and Its Importance for the 2017 Subaru Forester

The 2017 Subaru Forester definitely uses coolant as a critical part of its engine management system. Coolant, also known as antifreeze, plays a vital role in keeping the engine at the right operating temperature and ensuring reliable performance across a variety of driving conditions. So if you own or are considering a 2017 Forester, it helps to understand why coolant is used, what it does, and how to maintain it properly to keep your Subaru running smoothly.

At its core, the coolant in the 2017 Subaru Forester serves to regulate the engine temperature. The engine generates a lot of heat when it runs, and if that heat isn't controlled, the engine can overheat leading to damage. The coolant circulates through the engine via the cooling system, absorbing excess heat and carrying it to the radiator where it dissipates into the air. This cycle keeps the engine running at an optimal temperature balance.

On the flip side, cooling isn't the only job coolant does. It also protects the engine from freezing during cold weather. This antifreeze property prevents the liquid in the cooling system from turning into ice when temperatures drop. Since Australia can have colder regions and unpredictable weather, this feature is particularly handy for maintaining the integrity of the engine components in colder months.

Another important function of coolant is providing corrosion protection. The cooling system comprises several metal parts including the radiator, water pump, and engine components. Over time, exposure to water and air can lead to rust and corrosion which eventually causes leaks or blockages. Coolant contains additives that inhibit corrosion and keep the system clean and functioning well over the long haul.

Maintaining proper coolant levels and condition is an essential part of servicing your 2017 Subaru Forester. Running the vehicle with low or degraded coolant can lead to overheating, poor heater performance, or even engine damage. That's why Subaru recommends checking the coolant regularly and replacing it at specified intervals.

The recommended coolant type for the 2017 Subaru Forester is typically a long-life, ethylene glycol-based antifreeze with specific additives tailored for Subaru engines. Using the right type of coolant is crucial because mixing incompatible coolants can reduce effectiveness and cause damage. It's also important to dilute the coolant with the correct ratio of water - usually around 50/50 - to optimise protection against freezing, boiling, and corrosion.

When it comes to replacement, most Subaru workshops suggest changing the coolant approximately every 160,000 kilometres or every 10 years, whichever comes first. However, if the vehicle is driven under severe conditions such as very hot or cold climates, frequent short trips, or heavy towing, more frequent checks and earlier replacement may be needed. Regular servicing checks will usually include an inspection of the coolant colour and clarity to detect any contamination or deterioration.

Signs that your 2017 Forester's coolant system might need attention include the engine temperature gauge running hotter than normal, coolant leaks under the vehicle, a sweet smell inside the cabin, or heater performance that feels weak or inconsistent. Catching these issues early can save you from costly repairs and keep your Forester performing at its best.

For DIY enthusiasts, topping up the coolant is straightforward but it's important to do so with the engine cool to avoid burns. Also, avoid opening the radiator cap when the engine is hot as the system is pressurised, which can lead to dangerous coolant sprays. Always refer to the Forester's owners manual for specific coolant specifications and safety precautions.

In a nutshell, the coolant in the 2017 Subaru Forester is a vital fluid that does much more than just keep the engine cool. It protects against overheating, freezing, and corrosion, contributing to the vehicle's reliability and longevity. Keeping up with coolant maintenance and replacement as part of regular servicing is a smart move for any Forester owner looking to get the most out of their SUV with minimal hassle.
