Sump Plug Washers for the 2019 Mitsubishi Eclipse Cross: What You Need to Know

When it comes to servicing the 2019 Mitsubishi Eclipse Cross, one part that often comes up in discussions is the sump plug washer. If you're wondering whether this vehicle actually uses sump plug washers, the answer is yes, it does. These small but mighty components play an important role in your car's oil system and overall engine health.

The sump plug washer, sometimes called a crush washer or gasket, sits between the sump plug and the oil pan. Its main job is to create a tight seal that prevents engine oil from leaking out. Over time, as the sump plug is removed and reinstalled during oil changes, the washer can wear out, deform or become compressed, losing its ability to seal properly. This means replacing the sump plug washer when servicing your Eclipse Cross is a smart move.

So why exactly does the 2019 Mitsubishi Eclipse Cross use a sump plug washer? The answer lies in the nature of the sump plug and the need for a reliable seal. The sump plug threads directly into the oil pan, which is often made from aluminium or steel. Metal surfaces alone do not always provide the perfect seal, especially after repeated removal and tightening of the plug. The sump plug washer compensates for this by deforming slightly, sealing tiny imperfections between the plug and the pan surface to prevent leaks.

Leaving the old washer in place and reusing it can lead to oil leaks. Besides the mess, oil leaks can cause engine oil levels to drop, risking engine damage from inadequate lubrication. That's why many manufacturers, including Mitsubishi, recommend replacing the sump plug washer every time an oil change is performed. This is particularly important for your Eclipse Cross where the factory service schedule advises regular oil changes to keep the 1.5L or 2.0L turbo engines running smoothly.

When changing the oil on a 2019 Mitsubishi Eclipse Cross, you'll typically drain the old oil by removing the sump plug underneath the car. Before re-installing the plug, the old washer should be taken off and swapped out for a new one. These washers are quite inexpensive and easy to install, but essential for maintaining a proper seal. They are often made from soft metals like copper or aluminium, materials chosen specifically for their crush characteristics, allowing them to mould to the contact surfaces and tighten the seal around the sump plug.

It's important not to over-tighten the sump plug when changing the oil. Using the correct torque setting, usually found in the service manual, prevents damage to the sump plug threads and the washer. Too much force can deform the metal pan or strip the threads, leading to expensive repairs. Using the right washer ensures that proper torque can achieve a secure seal without leaks.

Over time and multiple oil changes, if sump plug washers aren't replaced regularly, they can lose their effectiveness resulting in small drips or noticeable oil seepage. Drivers might spot oil stains under the vehicle or low oil levels on the dipstick. Catching these problems early is easier when you change washers regularly. It also helps keep the environment cleaner by minimising oil leaks.

In addition to preventing leaks, the sump plug washer protects against contamination. When oil changes are made, contaminants can enter if the seal isn't tight, compromising engine performance and longevity. The washer helps keep dirt, dust and moisture from entering the oil system during changes, an often overlooked but vital benefit.

For owners who prefer to DIY their car maintenance, replacing the sump plug washer on a 2019 Mitsubishi Eclipse Cross is straightforward. After draining the oil, remove the sump plug and old washer, clean the plug and pan mating surfaces, fit a new washer on the plug, then reinstall using the correct torque. Following these steps ensures peace of mind knowing the engine oil system is properly sealed.

In short, the sump plug washer is a small but essential part of maintaining your 2019 Mitsubishi Eclipse Cross. While it might seem insignificant, its role in preventing oil leaks and protecting the engine is crucial. Replacing the washer at each oil change is a simple task that avoids headaches and costs down the track.

So next time your Eclipse Cross is due for servicing, don't overlook the humble sump plug washer. Taking care of this little component means your Mitsubishi runs smoother, cleaner, and longer.
