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

When it comes to the 2017 Subaru Legacy, checking the sump plug washers is definitely part of keeping your car in top shape. The sump plug washer plays a small but crucial role in preventing oil leaks from the oil pan drain plug. So if you own a 2017 Subaru Legacy, understanding why sump plug washers matter and how to take care of them is a smart move.

The 2017 Subaru Legacy uses a sump plug washer to create a tight seal between the sump plug and the oil pan. This washer is typically made from a crushable material such as aluminium or copper, designed to deform slightly when the sump plug is tightened. This deformation fills any minor gaps and ensures a leak-free fit that keeps the engine oil securely inside the sump, even under the constant vibration and heat from driving.

Using a washer on the sump plug is pretty common practice in modern vehicles like the Legacy. Without that washer, there's a much higher chance of oil leaking around the drain plug, which can cause annoying drips and lose valuable engine oil over time. Leaking oil can also lead to larger mechanical problems if left unchecked, so having a properly functioning sump plug washer helps maintain engine health.

Replacing or inspecting the sump plug washer should always be part of an oil change or routine servicing. Each time you remove the sump plug during an oil change, the washer is compressed and may no longer seal as effectively the next time it's reinstalled. Subaru recommends using a new washer at each oil change to avoid any potential leaks and to ensure that tight, proper seal is maintained.

Opting for a new washer is usually cheap and hassle-free, and it definitely beats dealing with oil leaks or losing engine oil. Many mechanics and even DIYers will simply stock up on a handful of washers to have them handy when it's time for an oil service. The washers are designed for one-time use only and should not be reused once removed.

When servicing your 2017 Subaru Legacy, the process to replace the sump plug washer is straightforward:

• Remove the sump plug carefully during your oil change.
• Take off the old washer - it may be crushed or deformed.
• Place a brand-new sump plug washer onto the plug, ensuring it fits snugly.
• Reinstall the sump plug, tightening it to the specified torque to avoid overtightening or damaging the threads.

Paying attention to this little detail can save time and money in the long run by preventing leaks and maintaining consistent oil pressure levels. Subaru specifies the torque setting for reinstalling the sump plug, so it's important to use a torque wrench if possible to avoid under-tightening or stripping the threads.

Another benefit of replacing the sump plug washer during service is peace of mind. No one wants to check under their car to find a puddle of engine oil after just having serviced it. A new washer means the sump plug seal is fresh, tight, and ready to protect your Legacy's engine.

Over time, heat cycles and vibrations can cause the washer to harden or crack. Reusing an old washer can result in poor sealing performance, which leads to the annoying risk of oil leakage. If you're regularly changing your oil and replacing the sump plug washer at the same time, you'll keep things clean and running smoothly.

Overall, the sump plug washer is that small but mighty part that often goes unnoticed until an oil leak shows up. For the 2017 Subaru Legacy, it's definitely a part you want to keep in check as part of your regular maintenance routine. Using a new washer each oil service helps to maintain a perfect seal, protect the engine, and give you confidence that your car's oil system is properly sealed and functioning.

If you aren't sure which washer fits your Subaru, consulting the owner's manual or visiting a Subaru dealership can help you get the correct part. Some washers are made from soft aluminium, while others may be copper, so having the right type ensures the best seal possible. Either way, the cost is minimal compared to the trouble of oil leaks.

In the end, sump plug washers may seem like a small, insignificant detail, but they play an essential role in keeping your 2017 Subaru Legacy's engine oil exactly where it needs to be - inside the sump, doing its job of lubricating and cooling the engine. Next time you're lined up for an oil change, remember the humble washer and give it the attention it deserves.
