Sump Plug Washers for the 2017 Subaru XV: What You Need to Know

When it comes to maintaining your 2017 Subaru XV, understanding the little parts that help keep everything running smoothly is always a bonus. One such part that often gets overlooked is the sump plug washer. This is a small but crucial component that plays a big role in keeping your engine oil where it belongs. So, does the 2017 Subaru XV use sump plug washers? And if it does, what should you know about them? Let's dive into it.

For the 2017 Subaru XV, sump plug washers are indeed relevant and used. Subaru utilizes a metal crush washer or a copper washer on the sump plug to ensure a tight, leak-free seal between the plug and the transmission or engine oil pan. These washers are designed to be deformed slightly when the sump plug is tightened, which helps prevent oil from leaking out. It is a simple but highly effective part of the vehicle's oil system.

The purpose of a sump plug washer is pretty straightforward. When you drain the oil for its regular change, the sump plug is removed. When you go to put it back, the washer ensures there are no tiny gaps or imperfections between the plug and the sump surface, which could potentially cause oil leaks. Without the washer, or with a worn one, you could end up with a slow leak that's hard to spot but bad news for your engine over time.

Because the sump plug washer crushes slightly during installation, Subaru and most manufacturers recommend replacing it every time the sump plug is removed. Reusing an old washer can compromise the seal, increasing the chance of leaks. It's a cheap and easy part to replace, and worth every cent to keep the job done properly.

For the 2017 Subaru XV, typically, the sump plug washer is made from aluminium or copper, materials chosen for their softness and malleability. This softness allows the washer to deform and fill any microscopic gaps effectively while still holding up to the high temperatures and pressures inside the sump. It is important not to substitute the washer with a non-recommended material, as it might not provide the correct seal or could damage the sump plug threads.

Maintenance wise, sump plug washers should be inspected and changed with every oil change. Since the Subaru XV's oil and filter service interval is generally around 10,000 to 12,500 kilometres under normal driving conditions, replacing the washer with every oil change is a good rule of thumb. This approach reduces the risk of oil leaks and potential engine damage due to low oil levels.

Replacing the sump plug washer is incredibly simple. When the oil is drained and the old plug is being refitted, the old washer is removed from the plug's thread, and a new washer is placed in position. The plug is then tightened to the manufacturer's torque specification. Over-tightening can damage the washer or the sump threads, while under-tightening might result in leaks, so using a torque wrench is highly recommended.

Ignoring the sump plug washer or reusing an old one might not cause immediate problems, but over time, oil leaks can develop. Oil leaks not only mean a messy driveway but, more importantly, lower engine oil levels, which can lead to poor lubrication and potentially serious engine damage. Considering the cost of a new sump plug washer is minimal, it's always wise to replace it during every oil change service on the Subaru XV.

Another important point to mention is that Subaru's official guidelines and service manuals usually specify the exact type and size of sump plug washer suitable for each model. For the 2017 Subaru XV, it's best to consult the vehicle's service handbook or speak with a Subaru specialist to source the correct part. Using genuine or approved aftermarket washers ensures the material and dimensions are up to standard for maintaining that perfect oil seal.

Finally, if any Subaru XV owner notices even a slight oil leak underneath their vehicle, checking the sump plug and its washer should be one of the first troubleshooting steps. Sometimes the leak might only be cured by swapping out a worn washer or retightening the plug to the correct torque. It is a small fix that can have big benefits for the health of the engine.

To sum it all up, sump plug washers on the 2017 Subaru XV are small but essential parts that help prevent oil leaks from the sump plug area. They are designed to be replaced at every oil change and must be fitted correctly to maintain a good seal and protect the engine oil system. Keeping these washers fresh and correctly installed is a simple step that contributes to the long-term reliability of the Subaru XV's engine and overall driving experience.
