What is the function of the oil drain plug washer?

The oil drain plug washer plays a crucial role in maintaining your vehicle’s engine by ensuring a tight seal between the oil drain plug and the oil pan. This prevents oil leaks, which can lead to engine damage if not addressed. Understanding its function and maintenance is essential for vehicle longevity.

Why is the Oil Drain Plug Washer Important?

The oil drain plug washer is a small yet vital component in your vehicle’s engine system. Its primary function is to create a secure seal to prevent oil leaks. Without this washer, oil could seep out, leading to decreased engine performance and potential damage.
