Understanding the Thermostat on the 2017 Mitsubishi ASX

The 2017 Mitsubishi ASX, like many modern vehicles, comes equipped with a thermostat as part of its engine cooling system. The thermostat plays a crucial role in maintaining the engine's optimal operating temperature, which is essential for performance, fuel efficiency, and longevity. Simply put, the thermostat acts as a temperature regulator, ensuring the engine warms up quickly and then stays at a consistent temperature once warmed.

As the engine starts cold, the thermostat remains closed to prevent coolant from circulating through the radiator. This allows the engine to reach its ideal operating temperature faster. Once this temperature is reached, typically around 88 to 95 degrees Celsius, the thermostat opens to allow coolant to flow through the radiator and prevent the engine from overheating.

Without a thermostat, the engine would take much longer to warm up, leading to increased fuel consumption, higher emissions, and premature wear and tear on engine components. By maintaining proper temperature, the thermostat helps the engine run efficiently and smoothly.

For owners of the 2017 Mitsubishi ASX, understanding the thermostat's function is important when it comes to servicing and maintenance. While it isn't a part that demands frequent replacement, the thermostat can wear out over time or stick in either the open or closed position, which can cause engine temperature problems.

When the thermostat is stuck closed, coolant cannot flow to the radiator, leading to overheating and potential engine damage. Conversely, if it gets stuck open, the engine may struggle to reach its normal operating temperature, resulting in poor fuel economy and increased emissions. This can also cause the cabin heater to blow cooler air, something you might notice on chilly mornings.

Because the thermostat is hidden inside the engine, you won't spot issues right away. Regular servicing of the cooling system is key, especially if the ASX is driven in stop/start city traffic, hot climates, or on extended highway trips. During regular maintenance, mechanics will often inspect the cooling system for leaks, coolant condition, and proper flow.

When it comes to replacing the thermostat on a 2017 Mitsubishi ASX, it's a task best left to skilled technicians, though DIY enthusiasts can tackle it with the right tools and a service manual. The job typically involves draining some coolant, removing parts of the intake manifold or other components to access the thermostat housing, swapping the faulty thermostat for a new one, replacing the gasket or seal, and refilling the cooling system with fresh coolant.

It is recommended to replace the thermostat every 100,000 kilometres or so, but this can vary depending on use and driving conditions. If the vehicle shows signs of temperature fluctuations, overheating, a faulty temperature gauge, or reduced heater performance, it might be time for a thermostat check.

Maintaining a healthy thermostat helps protect the engine from temperature extremes, reduces wear on internal parts, and helps maintain fuel economy and emissions standards. For owners of the 2017 Mitsubishi ASX, keeping an eye on the cooling system during routine servicing ensures the thermostat and related components work as they should, keeping the vehicle running smoothly and reliably for years to come.
