Oil Pan Crush Washer Sizes For Subaru Cars

The size of a Subaru oil pan crush washer varies depending on the model and year of the vehicle. For example, the oil pan crush washer for the 2015-2024 WRX model has a size of 14mm, while the 2011-2021 models have a size of 16mm. It is important to use the correct size of crush washer for your specific Subaru model to ensure a proper seal and prevent oil leaks.

The crush washer is a Subaru OEM part

The Subaru crush washer is available in different sizes, including 14mm and 16mm. It is recommended to replace the washer every time you change the oil to ensure a proper seal and prevent leaks. While some people choose to reuse the washer or use a different type of washer, it is not recommended as it may not provide an adequate seal and could lead to oil leaks.

You can purchase the Subaru crush washer online from various retailers, including Amazon and Oakos. It is also available at authorised Subaru dealerships. When purchasing, make sure to select the correct size for your vehicle and verify compatibility with your specific Subaru model and year.

It's recommended to replace the crush washer every time you change your oil

The Subaru oil pan crush washer comes in a 14mm or 16mm size. It is recommended to replace the crush washer every time you change your oil. This is because the crush washer is designed to take the stress off the threads on the oil pan and drain plug, and it is disposable. If you don't replace the crush washer, your oil might start leaking. This is a common issue that many Subaru owners have faced.

The crush washer is important because it ensures that you have tightened the drain plug correctly. It also helps to create a tight seal with the drain plug bolt, preventing oil leaks. While it may not be necessary to replace the crush washer every time you change your oil, it is a good practice to do so to avoid any potential leaks.

Some people choose to reuse their crush washers by flipping them over and using the other side. However, this is not recommended as the compression of the washer is crucial for maintaining a tight seal. Over time, the washer may become too thin and fail to create a proper seal, leading to oil leaks.

You can purchase crush washers in bulk or individually from dealerships, auto parts stores, or online retailers. They are relatively inexpensive, so it is worth replacing them to avoid any potential issues with your vehicle.

By replacing the crush washer regularly, you can ensure the proper functioning of your vehicle and prevent any oil leaks, which can cause damage to your engine and the environment.

The crush washer is designed to be used once

The crush washer is a crucial component in ensuring a tight seal for the oil drain plug, preventing oil leaks. Its design involves a soft metal composition, such as aluminium or copper, which allows it to conform effectively to the pan and plug, creating a uniform seal. This deformation is intentional and occurs when the washer is tightened.

However, crush washers are designed for single use only. Reusing a crush washer can lead to several issues. Firstly, the washer may not retain its sealing properties, as it is intended to deform and stay flat after the initial tightening. Reusing it may result in a slight leak, which, if left unattended, could lead to significant oil loss. Secondly, the washer may not provide the necessary torque to ensure a tight seal, potentially causing the plug to vibrate loose and resulting in an oil leak or, worse, the plug falling out and causing a complete oil dump. Lastly, the washer may not adequately protect the soft aluminium threads of the oil pan from stripping, which could occur if the plug is over-tightened.

Therefore, it is recommended to replace the crush washer every time the oil is changed. They are inexpensive and readily available, with some Subaru models even including them with oil filters. By prioritising this small investment, you can have peace of mind and avoid the potential hassles and costs associated with oil leaks.

As a Subaru owner, it is essential to be aware of the specific crush washer size for your vehicle. For instance, the 2011 to 2021 Subaru models, including the Outback, Legacy, Impreza, Forester, XV Crosstrek, BRZ, and WRX, utilise a 16mm crush washer with the part number 803916010.

The crush washer is 14mm or 16mm in size

The crush washer is an integral component in ensuring a tight seal for your Subaru's oil pan, preventing leaks. When it comes to the size of this part, it is important to note that there is not a one-size-fits-all approach. The correct size of the crush washer for your Subaru will depend on the specific model and year of your vehicle.

For instance, if you own a Subaru WRX from 2015 to 2024, or a BRZ/FR-S/86 model from 2013 to 2024, the appropriate crush washer size is 14mm. This information is specified by Subaru, the original equipment manufacturer (OEM), ensuring the part's precision and reliability.

On the other hand, for a range of Subaru models from 2011 to 2021, including the Outback, Legacy, Impreza, Forester, XV Crosstrek, and BRZ, the crush washer size is 16mm. This larger size is designed to fit these specific models, ensuring a secure fit and effective sealing of the oil pan.

It is worth noting that crush washers are typically designed for one-time use. Therefore, it is recommended to replace them with every oil change to maintain a tight seal and prevent leaks. By paying attention to the specific size requirements for your Subaru model, you can ensure a proper fit and effective oil pan sealing.

Additionally, when purchasing crush washers, it is advisable to buy them in bulk. This not only ensures that you have spares readily available, but it can also be more cost-effective than buying individual washers.

You can buy the crush washer in bulk

Crush washers are designed for one-time use, and it is recommended to replace them every time you change your oil. This is because crush washers are made to form a good seal with less torque, which is important for vehicles with aluminum oil pans. By using a new washer, you can ensure that your drain plug is properly torqued and sealed, reducing the risk of oil leaks. While some people may reuse their washers without issues, it is always better to be safe than sorry.

If you are looking to buy crush washers in bulk, there are several options available. You can try online retailers such as Amazon or eBay, which offer a variety of crush washers in different materials, sizes, and quantities. For example, Amazon offers a pack of 568 pieces of aluminum automotive engine oil pan drain plug gaskets in 18 different sizes. You can also find bulk packages of copper washers, which some people prefer as they can be reused a few times without leaking.

Another option for bulk crush washers is to look for wholesale or industry suppliers. For instance, Orion Tactical offers both retail and OEM bulk packages of crush washers in black steel and stainless steel, with various quantity options to choose from.

Additionally, you may want to consider buying oil filters and crush washers together in bulk. Some people have mentioned buying oil filters in bulk from Rockauto, and while they don't seem to sell bulk packages of crush washers, you can find them in packs of 6 or 12 from other online retailers.

Finally, it is worth noting that some people have suggested installing a Fumoto valve instead of using crush washers. While this may be a more convenient and long-lasting option, it is also more expensive. So, if cost is a concern, buying bulk crush washers and replacing them with each oil change is a more economical choice.
