Parts for your 2019 Mitsubishi Eclipse cross-Thermostat

Understanding the Thermostat in the 2019 Mitsubishi Eclipse Cross

The 2019 Mitsubishi Eclipse Cross, like most modern vehicles powered by a petrol or diesel engine, comes equipped with a thermostat as part of its cooling system. While some newer vehicles with advanced cooling methods or electric water pumps might skip traditional thermostats, the Eclipse Cross sticks with the tried and true mechanic-friendly thermostat to regulate engine temperature and keep everything running smoothly. So, what's the deal with this little part, and why should owners care about it during servicing? Let's dive into it.

At its core, the thermostat is a valve that sits between the engine and the radiator. Its job is to help the engine reach - and maintain - optimal operating temperature as quickly as possible. When you start your Eclipse Cross from cold, the thermostat remains closed, stopping coolant from flowing through the radiator. This allows the engine to warm up rapidly to its ideal temperature, usually around 90 to 100 degrees Celsius. Once the engine hits this sweet spot, the thermostat opens up, letting coolant flow into the radiator to control the temperature and prevent overheating.

Why's that important? Well, engines that run too cold aren't as efficient and can produce higher emissions. Conversely, if the engine runs too hot, you risk damage to internal components or even a blown head gasket. The thermostat helps maintain that balance, ensuring smooth performance, better fuel economy, and a longer engine life.

For the 2019 Mitsubishi Eclipse Cross, the thermostat is a simple mechanical unit housed within the engine's cooling system. It's designed to withstand daily driving and Australia's wide-ranging climate - from scorching summer temperatures to chilly mornings. Even though it's built to last, the thermostat isn't a "fit it and forget it" part. Over time, it can get stuck open or closed due to wear, corrosion, or deposits affecting its valve and wax pellet mechanism.

If the thermostat gets stuck open, the coolant circulates through the radiator regardless of the engine's temperature, causing the engine to run cooler than intended. This might mean you notice poorer heater performance inside the cabin and reduced fuel economy. If stuck closed, the thermostat won't let coolant flow through the radiator at all, creating an overheating risk that can lead to costly engine repairs if not caught early.

So what's a good approach when it comes to the thermostat on the Eclipse Cross? Professional servicing technicians usually inspect the cooling system during a regular service and will check for signs that the thermostat might be failing. This might include checking engine temperature during warm-up, inspecting hoses for proper heat, or even removing and bench-testing the thermostat. Although it's not a common replacement item like spark plugs or oil filters, a faulty thermostat should be replaced promptly to avoid engine damage.

Replacement is fairly straightforward and can usually be done in a couple of hours by a qualified mechanic. The part itself isn't too pricey and is readily available, often supplied as an original Mitsubishi part or a reliable aftermarket equivalent. When replacing the thermostat, it's a good idea to also check the condition of the coolant and hoses and perform a coolant flush if necessary. This helps maintain the entire cooling system's efficiency.

Maintaining the thermostat and cooling system is particularly important in Australia's harsh climate where summer heat puts extra strain on engine cooling. Dusty conditions and long highway drives can also contribute to wear and tear. Simple steps like regular fluid checks, watching engine temperature gauges, and staying on top of scheduled servicing can keep your Eclipse Cross running smoothly for years.

In a nutshell, the thermostat in the 2019 Mitsubishi Eclipse Cross plays a vital role in keeping engine temperatures regulated for performance, efficiency, and durability. While it might be small and often overlooked, neglecting the thermostat and the cooling system could lead to bigger, more expensive problems down the road. So whether it's time for your routine service or you notice any signs of temperature trouble, getting the thermostat checked out is a smart move to keep your Mitsubishi running at its best.
