Sump Plug Washers for the 2021 Mitsubishi Eclipse Cross: What You Need to Know

The 2021 Mitsubishi Eclipse Cross is a well-engineered SUV that has garnered a good reputation for reliability and performance. When it comes to routine maintenance, one key component that often comes up is the sump plug washer. But are sump plug washers actually used in the 2021 Mitsubishi Eclipse Cross? And if so, what role do they play? Let's have a chat about that.

For those unfamiliar, a sump plug washer, also known as a crush washer or sealing washer, is a small but essential part that sits between the sump plug (or drain plug) and the oil pan. Its main role is to create a tight seal that prevents engine oil from leaking out after an oil change. It's a simple component, but without it, you could be looking at oil drips or even serious leaks that can cause engine damage over time.

When referencing official Mitsubishi technical documentation as well as trusted automotive maintenance sources, it's clear that the 2021 Mitsubishi Eclipse Cross does indeed use sump plug washers as part of its engine oil drain system. This means that every time the oil gets changed, the washer should be inspected and typically replaced.

Why is the sump plug washer replaced with every oil change? The answer lies in how these washers are designed. Most sump plug washers for the Eclipse Cross are made of a soft metal, commonly aluminium or copper. When the sump plug is tightened after draining old oil, the washer crushes slightly to form a seal that conforms to the surface of the oil pan. Once crushed, the washer doesn't return to its original shape, so reusing it can mean the seal isn't as tight. This can lead to leaks.

Here is why sump plug washers matter for the 2021 Mitsubishi Eclipse Cross:

• They provide a secure, leak-proof seal between the sump plug and oil pan.
• The soft metal construction allows the washer to conform perfectly to any minor irregularities.
• Replacing the washer each time helps avoid risks of oil leaks, which can cause engine damage or safety hazards.
• Using the correct washer ensures proper torque is applied to the sump plug without damaging the oil pan threads.

From a maintenance perspective, keeping an eye on the sump plug washer is important but often overlooked by DIYers and even some workshops. When servicing the 2021 Mitsubishi Eclipse Cross, it pays to get that new washer in place. They are inexpensive but play a surprisingly vital role.

Here are some top tips for dealing with sump plug washers on the 2021 Mitsubishi Eclipse Cross:

1. Always replace the washer at every oil change. Even if the washer looks okay, it's best practice to swap it out for a brand new one to ensure a perfect seal.
2. Use the right washer type and size. Mitsubishi specifications will usually call for a particular size and metal type (most commonly aluminium). Using the wrong size or material can lead to poor sealing or damage.
3. Torque the sump plug correctly. Over-tightening can crush the washer too much and also damage the oil pan threads, while under-tightening can cause leaks. Refer to the official service manual for torque specs.
4. Inspect the sump plug and oil pan mating surface for damage. If either part is scratched or dented, the washer might not seal properly.
5. Check for leaks after installation. After an oil change with a new washer fitted, run the engine briefly and inspect underneath for any signs of oil drips around the sump plug.

Neglecting sump plug washer replacement can lead to slow oil leaks that might go unnoticed until engine oil is significantly low. That can spell trouble for your Mitsubishi Eclipse Cross's engine and lead to costly repairs down the road. Keeping these little washers fresh is a no-brainer maintenance step.

In short, if you own a 2021 Mitsubishi Eclipse Cross or are servicing one, make sure the sump plug washer is on your checklist. It is a small, inexpensive item that protects your engine's oil and extends the longevity of your vehicle. Plus, it takes just a moment to replace, but pays off huge in peace of mind and engine protection.
