Sump Plug Washers on the 2017 Subaru Exiga: What You Need to Know

When it comes to servicing a 2017 Subaru Exiga, one of the small but important parts you might hear about is the sump plug washer. This little washer might not seem like much, but it plays a crucial role in keeping your car's engine oil safely inside the sump. If fitted to the 2017 Subaru Exiga, the sump plug washer is a key component that ensures a proper seal between the sump plug and the oil pan.

In many vehicles, including some Subaru models, sump plug washers are either copper or aluminium. They act as a crush washer, meaning they deform slightly when tightened, creating a tight seal to prevent oil leaks. This is essential because any leak in the sump plug could lead to oil loss, potentially harming engine performance or worse, causing engine damage.

Researching the technical sources and repair manuals for the 2017 Subaru Exiga reveals that the sump plug does indeed use a washer. Subaru typically recommends replacing the sump plug washer each time the oil is changed. That's because the washer is designed for single use, once it's crushed and deformed, it loses the ability to create a reliable seal if reused.

So why is this important? Well, the sump plug washer is a cheap and simple part but installation with a used or damaged washer can lead to tiny gaps or uneven seals. Over time, this can cause oil drips or leaks under your car. Fixing an oil leak could mean additional service time and cost, which most owners would rather avoid.

Replacing the sump plug washer on a 2017 Subaru Exiga is an easy job but it needs to be done properly. Whenever an oil change is performed, the mechanic should remove the sump plug, replace the washer with a new one, and then tighten the plug to the manufacturer's torque specification. This ensures that the washer compresses correctly making the seal reliable.

Here are the key reasons why sump plug washers are used and should be replaced during servicing:

• They create a leak-proof seal between the sump plug and oil pan.
• The washers deform to fill small imperfections improving the seal.
• They are designed for one-time use only and must be replaced each oil service.
• Using a new washer prevents oil leaks and avoids costly repairs.
• Maintains engine oil integrity and protects engine health.

If you're doing your own oil changes on the 2017 Subaru Exiga, don't overlook the sump plug washers. It is tempting to reuse the old washer to save money, but it's not a recommended practice. The washer is pretty inexpensive, so splashing out on a new one helps protect your engine and avoid oil seepage.

Here's what a typical sump plug washer replacement involves during an oil change:

1. Drive the vehicle up on ramps or jack it safely to allow access to the sump plug.
2. Place a suitable container under the sump to catch draining oil.
3. Carefully unscrew the sump plug and drain the oil fully from the engine.
4. Remove the old sump plug washer from the plug. It might be stuck slightly, so gently pry it off if needed.
5. Fit a new washer onto the sump plug.
6. Screw the sump plug back into position, tightening it to the torque specification provided in the Subaru Exiga service manual (usually specified in Newton metres).
7. Refill the engine with fresh oil, checking levels to the recommended amounts.
8. Dispose of old oil and washers responsibly according to local regulations.

Subaru service guidelines emphasise the importance of using the right washer type for the sump plug. Often, dealers and parts suppliers will specifically sell the OEM washer designed for the car's sump plug diameter, thread, and crush properties. Using an off-the-shelf or incompatible washer can compromise the seal.

While it might seem like a small item, the sump plug washer is a vital part of your 2017 Subaru Exiga's oil system maintenance. A proper seal prevents engine oil leaks which can save money in potential repairs down the track and ensure your car's engine runs smoothly. Regular maintenance as part of servicing means changing the sump plug washer at each oil change for peace of mind.

Next time your Subaru Exiga is due for an oil change, check that the sump plug washer is getting a fresh replacement. This small step keeps your engine sealed tight and running reliably mile after mile.
