Parts for your 2016 Subaru Exiga-Sump plug washers

Sump Plug Washers on the 2016 Subaru Exiga: What You Need to Know

When it comes to servicing a 2016 Subaru Exiga, especially during an oil change, one of the small yet important parts you'll hear about is the sump plug washer. These washers, also known as crush washers or sealing washers, are designed to create a tight seal between the sump plug and the oil pan, helping prevent oil leaks. But do they actually fit on a 2016 Subaru Exiga? The answer is yes - the 2016 Subaru Exiga does use sump plug washers, and they play a vital role in keeping the engine oil where it should be.

The sump plug washer is usually a simple component made from soft metal such as copper or aluminium. It sits between the sump plug and the oil pan's surface. When the sump plug is tightened, the washer slightly deforms or "crushes" to fill any microscopic gaps or irregularities, creating a leak-proof seal. Without this washer, even the tiniest gap can result in slow oil drips that might go unnoticed until they cause engine damage. So for the Subaru Exiga, these washers are far from redundant.

During routine maintenance, such as oil and filter changes, the sump plug washer will almost always need to be replaced. That's because once a crush washer has been compressed and tightened, its shape is altered, and it won't seal properly if reused. Subaru themselves recommend replacing the washer with every oil change to maintain a tight, leak-free seal. Many mechanics and car enthusiasts make it a habit to change the sump plug washer each time the oil is drained, just to eliminate any chance of leaks - which is smart given the cost and hassle of dealing with oil spills or low oil levels.

It's also worth noting that using the right type of sump plug washer is important. Mixing materials or using a worn washer can cause improper sealing and early leaks. Subaru's official service manuals specify the washer type and size for the Exiga: a copper crush washer designed to match the sump plug thread size and oil pan surface. Sourcing a genuine or high-quality replacement washer is well advised to avoid any trouble.

For those who like to service their 2016 Subaru Exiga at home, here are a few friendly tips to keep in mind when handling sump plug washers during an oil change:

• Always replace the sump plug washer with a new one specifically designed for the 2016 Subaru Exiga.
• Ensure the sump plug threads and oil pan sealing surfaces are clean before installing the new washer and tightening the plug.
• Use a torque wrench to tighten the sump plug to the manufacturer's recommended torque setting. This prevents overtightening which can crush the washer too much or strip the threads.
• Check periodically for leaks, particularly after the first few hundred kilometres following an oil change.

By taking sump plug washers seriously, Subaru Exiga owners can maintain a healthy engine for years to come. Not only do these small washers stop leaks, they also help keep the lubricating oil inside the engine where it belongs. Overlooking them or reusing old washers might seem like a minor thing, but the potential for oil leaks and the resulting engine damage makes sump plug washers a key component in vehicle maintenance.

In the grand scheme of things, sump plug washers are a classic example of a part that flies under the radar until something goes wrong. They are cheap, easy to replace, and an essential part of your oil change routine. For the 2016 Subaru Exiga, following the manufacturer's guidelines on sump plug washer replacement will keep the engine running smoothly and avoid unnecessary mess or repair bills. It's one of those simple habits that go a long way in keeping your vehicle healthy and reliable.
