Sump Plug Washers on the 2021 Mitsubishi ASX: What You Need to Know

When it comes to the 2021 Mitsubishi ASX, sump plug washers are indeed relevant and an important part of the vehicle's maintenance routine. The sump plug washer might seem like a small, insignificant component, but it plays a vital role in keeping your engine oil where it should be, preventing leaks and ensuring your vehicle runs smoothly.

So, what exactly is a sump plug washer, and why does the 2021 Mitsubishi ASX need one? Simply put, the sump plug washer is a ring-shaped gasket that sits between the sump plug (the bolt that drains your engine oil) and the sump itself. It's designed to create a tight seal that stops engine oil from leaking out of the drain hole after the sump plug has been tightened back in place.

Why is this important? Well, the sump is the oil reservoir at the bottom of the engine where used oil collects before it gets pumped back through the engine for lubrication. Without a proper seal, oil can drip out. Losing engine oil not only creates a mess under the vehicle but more importantly, it puts the engine at risk. Running low on oil leads to increased friction, overheating, and potentially, costly engine damage.

The 2021 Mitsubishi ASX uses a copper or aluminium crush washer as the sump plug washer. These materials are chosen because they deform slightly under pressure, sealing imperfections between the sump plug and the sump. Over time, the existing washer can become compressed or damaged, so replacing it during every oil change is a smart move.

Many workshops and experienced DIY mechanics recommend changing the sump plug washer whenever the sump plug is removed - that is, every time you do an oil change. This ensures a proper seal and minimises the risk of oil leaks. It's a small component that doesn't cost much but can save a lot of hassle if overlooked.

Maintaining the sump plug washer properly includes:

• Inspecting the washer for signs of damage, such as cracking, excessive flattening, or corrosion
• Replacing the washer each time the sump plug is undone during an oil change
• Ensuring the sump plug is tightened to the manufacturer's specified torque to compress the washer correctly without causing damage

Not using a new sump plug washer or reusing an old one can cause the seal to fail, leading to slow oil leaks. These leaks might not be noticeable straight away but can add up over time, potentially leading to low oil levels and engine wear. It's a classic example of how small maintenance details make a big difference.

For owners of the 2021 Mitsubishi ASX, the good news is that sump plug washers are readily available and affordable parts. Genuine Mitsubishi washers can be found through dealerships, while quality aftermarket washers are also an option. It's worth sourcing the right size and material to match the original equipment.

When servicing the 2021 ASX, whether at a dealership or a local mechanic, changing the sump plug washer is standard practice during oil drain plug removal. This small routine step keeps your oil system tight and your engine protected.

In everyday terms, using a new sump plug washer when you next service your ASX is like putting on a fresh gasket seal. It helps keep the oil where it belongs and avoids headaches from messy leaks or potential engine damage. Considering the cost and ease of replacement, it's one of those straightforward things that helps keep your vehicle reliable and running well for years.

So, next time the oil change is due on your 2021 Mitsubishi ASX, make sure the sump plug washer is part of the checklist. It's the little detail that helps your engine stay happy and your drive smooth.
