Thermostat Housing on the 2018 Mitsubishi Eclipse Cross: What You Need to Know

The 2018 Mitsubishi Eclipse Cross is a popular compact SUV that combines style and functionality, making it a great choice for Aussie drivers. When it comes to maintaining this vehicle, especially its cooling system, the thermostat housing plays an important role. For owners or those curious about the inner workings of their Eclipse Cross, understanding the thermostat housing is key.

The thermostat housing is definitely fitted on the 2018 Mitsubishi Eclipse Cross. It is a critical component that houses the thermostat itself and connects it to the vehicle's cooling system. This part is typically attached to the engine block or cylinder head, serving as the gateway for coolant flow regulation. Without a thermostat housing, there would be no organised point to manage the thermostat or route coolant properly through the engine's cooling pathways.

The primary purpose of the thermostat housing is to hold the thermostat in place and provide a sealed connection between the engine and the radiator hoses. The thermostat inside this housing is a clever little valve that regulates the engine's temperature by controlling the flow of coolant. When the engine is cold, the thermostat remains closed, preventing coolant from circulating to the radiator. This allows the engine to warm up quickly to its optimal operating temperature.

Once the engine reaches this temperature, typically around 90°C, the thermostat opens and allows coolant to pass through to the radiator where it is cooled before cycling back through the engine again. The thermostat housing ensures this whole process runs smoothly by securely holding the thermostat and connecting all the necessary hoses and components.

For someone maintaining their 2018 Mitsubishi Eclipse Cross, the thermostat housing is an important part to keep an eye on. Over time it can experience wear and tear like any component exposed to heat and coolant. The housing is often made from plastic or aluminium, and the plastic versions can become brittle or crack due to constant thermal expansion and contraction. This can lead to coolant leaks, which may cause the engine to overheat if not addressed promptly.

When it comes to servicing or replacing the thermostat housing on the Eclipse Cross, a few key points are worth mentioning:

• Inspect for leaks - regularly check around the thermostat housing for any signs of coolant leaks, such as dampness, corrosion, or coolant stains. Because leaking coolant not only lowers the coolant level but also affects engine temperature control, it should be addressed at the first sign.
• Replace the thermostat - often when replacing the thermostat housing, it's best practice to replace the thermostat as well. These two components work hand in hand and doing both at once can save time and inconvenience.
• Use OEM parts - Mitsubishi parts, or high-quality aftermarket parts that meet or exceed OEM specifications, are recommended. This ensures proper fitment and durability, as well as reliable engine cooling performance.
• Gasket and sealing - the thermostat housing comes with a gasket or O-ring to seal the connection and prevent leaks. Always replace these seals whenever the housing is removed or replaced to maintain a tight seal.
• Coolant flush - when replacing the thermostat housing or thermostat, it's also a good opportunity to flush the cooling system and top up with fresh coolant. Old or contaminated coolant reduces the efficiency of the cooling system and can cause premature component wear.

Maintenance intervals for coolant system components including thermostat and housing depend on driving conditions and coolant type used, but many mechanics recommend checking the thermostat housing every 50,000 to 100,000 kilometres or as part of regular major servicing. Keeping this part in good condition helps prevent overheating issues, engine damage, and can improve fuel economy by ensuring the engine runs at its ideal temperature.

DIY enthusiasts can tackle thermostat housing replacement on the Mitsubishi Eclipse Cross with the right tools and know-how, though some caution is advised. The cooling system will need to be drained to avoid spillage and ensure safety, and reassembly must be done carefully to prevent leaks and guarantee correct coolant flow. If unsure, it's always a good idea to have a trusted mechanic handle the job.

Overall, the thermostat housing is a small but mighty component in the 2018 Mitsubishi Eclipse Cross's engine cooling system. It plays a crucial role in managing engine temperature and ensuring the vehicle runs efficiently. Whether for routine maintenance or fixing leaks, paying attention to the thermostat housing can keep the Eclipse Cross performing at its best and avoid costly overheating repairs in the future.
