Sump Plug Washers for the 2016 Subaru Forester: What You Need to Know

The 2016 Subaru Forester is a reliable and well-loved SUV, especially popular in Australia for its rugged capability and trusty performance. When it comes to routine maintenance, particularly oil changes, one question that often pops up is about sump plug washers. Are they used on the 2016 Forester, and if so, why are they important? Let's take a look based on technical references and practical know-how.

For the 2016 Subaru Forester, sump plug washers are indeed relevant and are commonly fitted. These washers play a crucial role during oil changes, as they provide a reliable seal between the sump plug and the oil pan. Without a proper washer, the sump plug may not seal properly, leading to potentially messy and damaging oil leaks.

In many Subaru vehicles, including the 2016 Forester, the oil drain plug threads directly into the sump or oil pan. The sump plug washer sits between the plug head and the sump surface, creating a tight seal. Typically these washers are made from a soft metal like aluminium or copper, which deforms slightly when tightened. This deformation helps mate the surfaces perfectly to prevent any oil seeping out.

Using the correct sump plug washer is important. Many Subaru specialists recommend replacing the washer each time you do an oil change. The reasoning is simple: these washers are designed as crush washers, which means they deform once to create a seal. Trying to reuse one risks leaks as the washer loses its original shape and sealing ability.

Here's a bit more detail about why sump plug washers matter for the 2016 Forester:

• Prevents leaks: The main purpose of the washer is to stop oil from leaking. Oil leaks around the sump plug can cause engine problems and reduce oil levels.
• Protects the sump: Without a proper washer, the sump plug might damage the oil pan threads by overtightening, or cause vibrations that loosen the plug over time.
• Easy maintenance: Replacing the washer during an oil change is a small and inexpensive step that can save headaches and costly repairs down the track.

When it comes to replacing sump plug washers on a 2016 Subaru Forester, it's a straightforward process but deserves attention. Here's the typical approach:

• Remove the old sump plug when draining the oil.
• Take off the old washer carefully. Sometimes it sticks to the sump plug or the oil pan surface.
• Inspect the sump plug for any damage or wear, and clean it to remove grime or old oil residue.
• Fit a new Subaru-approved aluminium crush washer onto the sump plug.
• Screw the sump plug back into the sump and tighten it to the correct torque specification. Too tight can strip threads or damage the washer, and too loose can cause leaks.

It's also worth noting that some Subaru owners use aftermarket magnetic sump plug washers or combined plug-washer kits. These units include a magnet to attract any tiny metal debris in the oil. While not original equipment, they can be a nice added feature to help protect engine internals and improve longevity.

Choosing the right sump plug washer is important. Subaru recommends genuine parts or high-quality equivalents to ensure correct material and thickness. Using an incorrect washer can lead to ineffective sealing or damage to the sump plug threads.

Regular maintenance involving sump plug washers during oil changes not only protects the engine but is also a very budget-friendly way to keep the Forester running smoothly. Considering oil changes usually happen around every 10,000 to 15,000 kilometres depending on the oil and driving conditions, replacing the sump plug washer each time is a small but valuable habit.

All in all, the 2016 Subaru Forester does make use of sump plug washers as part of its oil system design. They may seem like minor parts, but their role in sealing the sump plug and preventing leaks is crucial. With proper attention and replacement as part of servicing, drivers can keep their Forester's engine well lubricated and protected, avoiding unnecessary mess and engineering problems.
