Sump Plug Washers for the 2013 Mazda CX-5: What You Need to Know

The 2013 Mazda CX-5 is a popular choice for many drivers here in Australia thanks to its combination of style, fuel efficiency and practical features. When it comes to basic servicing and maintenance, one small but important part often discussed is the sump plug washer. Some might wonder if the 2013 Mazda CX-5 even uses a sump plug washer, and if so, why it is important to keep an eye on it.

First off, the sump plug washer is definitely relevant and used on the 2013 Mazda CX-5. This little component may not be the flashiest part under the vehicle but it plays a crucial role in ensuring your oil stays right where it should be. The sump plug washer sits between the sump plug and the oil pan, essentially providing a tight seal that stops oil from leaking out when the sump plug is tightened.

The whole purpose of a sump plug washer is to help create a proper seal against the metal surfaces between the sump plug and the oil pan bottom. Without a good washer, or if the washer has been reused past its useful life, there's a greater chance of oil seeping or dripping from the sump drain area. That kind of leak could lead to low engine oil levels, which over time may cause engine damage or performance problems if left unaddressed.

For Mazda CX-5 owners, using the right type of sump plug washer during an oil change or any sump plug removal is essential. Often, Mazda specifies the use of a crush washer or a copper washer that conforms and compresses to fill any minor gaps between the plug and sump. This crush action forms a better seal than just metal-on-metal contact. Importantly, Mazda recommends changing this washer every time the sump plug is removed rather than reusing an old one, as washers tend to deform or harden with repeated use.

Ignoring the condition of the sump plug washer can lead to a slow oil leak that might go unnoticed for a while. Regular servicing intervals for the Mazda CX-5 typically include an oil and filter change about every 10,000 to 15,000 kilometres depending on driving conditions. Every time the oil is drained, the sump plug washer should be checked and ideally replaced to maintain that essential seal. This is a quick and low-cost maintenance item that can save quite a bit of hassle and expense down the track.

When servicing the 2013 Mazda CX-5's sump plug washer or advising others, it pays to highlight a few points:

• The washer is not a permanent seal and should be replaced at each oil change for best reliability.
• Using the correct size and type (typically copper or alloy crush washers) ensures the best seal and avoids overtightening the plug, which can damage the sump threads.
• If removing the sump plug for any reason, inspect the washer closely. If it looks flattened, cracked or worn, replace it immediately.
• Never reuse old washers. Even if they look okay, their sealing integrity is reduced after being crushed once.
• Proper torque of the sump plug with new washer is important. Too loose risks leaks, too tight risks damaging threads or warping the sump pan.

For DIY enthusiasts who care about keeping their Mazda CX-5 in top shape, having a spare set of new sump plug washers on hand is a smart idea. They are inexpensive parts but can prevent annoying oil leaks and potentially costly engine problems from oil starvation. If you take your vehicle to a mechanic, most reputable workshops will automatically replace this part with every oil change as part of their service routine.

It's also worth noting that in some modern vehicles, specialised sealant-type washers might be used instead of traditional crush washers. But for the 2013 Mazda CX-5, the manufacturer's recommendation remains clear: use a proper crush-type sump plug washer and replace it every time the sump plug is removed.

In the end, the sump plug washer may be small and easily overlooked, but it plays a vital role in the health of the Mazda CX-5's engine. Maintaining this part during oil changes helps keep the oil where it needs to be, ensures clean running, and avoids leaks that could lead to bigger problems. Whether taking your car in for a professional service or tackling the job yourself, don't forget to give this humble washer the attention it deserves.
