2016 Subaru Impreza Thermostat: What It Does and Why Maintenance Matters

The 2016 Subaru Impreza comes equipped with a thermostat as an essential part of its cooling system. Like most modern vehicles, the thermostat plays a crucial role in regulating engine temperature and ensuring the car runs efficiently. So if you're driving a 2016 Subaru Impreza, it's important to know what the thermostat does and why taking care of it during servicing can keep your vehicle in good nick.

Simply put, the thermostat is a valve located between the engine and the radiator. Its job is to control the flow of coolant to the radiator based on the engine's temperature. When you first start the Impreza on a chilly morning, the thermostat stays closed. This stops coolant from flowing to the radiator, allowing the engine to heat up quickly to its ideal operating temperature. Once the engine reaches around 88 to 90 degrees Celsius, the thermostat opens up, letting coolant circulate and preventing the engine from overheating.

This clever valve helps the engine warm up faster, improving fuel efficiency and cutting down on emissions. It also keeps engine parts safe by preventing them from running too hot or too cold. Without a thermostat, the Impreza's engine would take longer to warm up, which could hurt performance and fuel economy, and even cause excessive engine wear over time.

Like any mechanical part, the thermostat in a 2016 Subaru Impreza can wear out or get stuck over years of use. When it fails, you might notice the engine running hotter than normal or never reaching operating temperature. This might cause the heater inside the cabin to blow cold air or make the vehicle struggle with performance and fuel consumption. If not checked, a faulty thermostat can lead to engine overheating and severe damage.

When it comes to maintenance and replacement, the thermostat is generally not a regular wear item you need to swap out frequently. However, it's a good idea to have it tested during regular servicing, especially if you notice any signs of overheating or temperature problems. Your mechanic can check if the thermostat opens and closes as it should, or replace it as part of a cooling system or radiator service. Replacing the thermostat typically involves draining some coolant, removing the thermostat housing, swapping out the valve, and refilling the coolant.

Keeping an eye on the cooling system and thermostat helps avoid costly repairs down the line. Using quality coolant and changing it at recommended intervals also supports the thermostat function by preventing corrosion and deposits that might cause the valve to stick.

Many drivers overlook the thermostat because it is a small, hidden component. But it's working away quietly every time the engine is running to make sure everything stays at the right temperature. So whether you're doing routine maintenance or you notice performance or temperature issues, don't forget this small part. A healthy thermostat contributes to a smooth, efficient drive and helps keep the 2016 Subaru Impreza running just right for years to come.
