Understanding the Thermostat in the 2017 Subaru XV: Purpose, Maintenance, and Replacement Advice

The 2017 Subaru XV, also known as the Crosstrek in some markets, is a popular compact SUV that combines rugged capability with everyday practicality. Like many modern vehicles, it is equipped with a cooling system designed to keep the engine operating at an optimal temperature. A key component of this system is the thermostat. Contrary to some speculation, the 2017 Subaru XV does indeed use a thermostat as part of its engine cooling arrangement.

The thermostat is a small but critical valve located between the engine and the radiator. Its main job is to regulate engine temperature by controlling the flow of coolant. When the engine is cold, the thermostat remains closed, preventing coolant from flowing to the radiator. This helps the engine warm up quickly to its ideal operating temperature. Once the engine reaches this temperature, typically around 88 to 96 degrees Celsius, the thermostat opens, allowing coolant to circulate through the radiator and dissipate excess heat. This regulation protects the engine from overheating while ensuring efficient fuel combustion and reduced emissions.

In the context of the 2017 Subaru XV, the thermostat plays an equally important role in maintaining performance and reliability. Subaru's flat-four 'boxer' engine, paired with a variable valve timing system, works best within a narrow temperature range. The thermostat ensures that the engine reaches this temperature without delay after start-up and stays within this ideal window during operation. Temperatures that are too low or too high can lead to increased engine wear, reduced fuel efficiency, and higher exhaust emissions.

Replacing or maintaining the thermostat in a 2017 Subaru XV should not be overlooked, especially as the vehicle racks up mileage over the years. Thermostats can become stuck open or closed due to wear, corrosion or debris in the cooling system, leading to engine performance issues. A stuck-open thermostat causes the engine to run too cool, resulting in poor fuel efficiency, sluggish heater performance inside the cabin, and increased emissions. On the other hand, a stuck-closed thermostat prevents coolant from circulating through the radiator, which can quickly lead to overheating and severe engine damage.

When servicing the cooling system on the 2017 Subaru XV, it's a good practice to inspect the thermostat for proper operation. Signs that it might be failing include:

• Engine temperature fluctuations or temperature gauge readings that stay abnormally low or high
• Engine overheating episodes
• Heater not producing warm air inside the cabin during cold weather
• Coolant leaks around the thermostat housing
• Unexplained engine performance problems linked to temperature

Thermostat replacement on the Subaru XV is a straightforward job, but it usually requires draining some coolant and removing the thermostat housing. Subaru's cooling system uses a compact, sealed thermostat design which means that once the housing is open, replacing the thermostat is recommended rather than attempting repairs or cleaning. Using an OEM-quality thermostat ensures that heat management remains precise and reliable.

Routine servicing of the thermostat should coincide with regular coolant flushes, typically recommended every 60,000 kilometres or as per Subaru's servicing schedule. Fresh coolant is less likely to cause corrosion or deposit build-up that could interfere with the thermostat's operation. Moreover, replacing the thermostat during a coolant flush can save labour costs and prevent future cooling system failures.

In addition to replacement, maintaining the thermostat involves keeping an eye on the entire cooling system's health, including radiator condition, water pump operation, hoses, and radiator cap sealing. Any malfunction within these components can indirectly affect thermostat function and engine temperature control.

The thermostat also impacts cabin comfort and emission controls. Since the heating system inside the vehicle relies on hot coolant circulation, a faulty thermostat can lead to cold drafts or inadequate heater output in winter. Furthermore, incorrect engine temperature affects catalytic converter efficiency and overall emission levels.

For Subaru XV owners, consulting the vehicle's servicing manual or authorised Subaru technicians can provide specific part numbers and detailed procedures for thermostat inspection and replacement. Genuine Subaru parts and service enhance the reliability and longevity of the vehicle's cooling system.

Keeping the thermostat in top shape not only protects the engine but also improves fuel economy, reduces emissions, and maintains comfort for passengers. Overlooking this small component can lead to costly repairs down the track. So if a 2017 Subaru XV owner notices any odd behaviour related to engine temperature or heating performance, a thermostat check should be on the to-do list without delay.

To wrap things up, the thermostat in the 2017 Subaru XV is definitely present and plays a vital role in managing engine temperature. Regular inspection, maintenance, and timely replacement help keep this component working efficiently and contribute to the overall health and performance of the vehicle. It is well worth the attention it receives during servicing.
