This is a genuine TOYOTA oil drain plug washer, specifically designed to fit various TOYOTA models. The part number is 90341-10011, and it is manufactured in Japan (JP). A properly functioning oil drain plug washer is crucial for maintaining the integrity of your engine's oil system. It creates a tight seal between the drain plug and the oil pan, preventing any oil from leaking out during operation. Over time, these washers can degrade or become compressed, leading to potential leaks. Replacing your oil drain plug washer with a genuine TOYOTA part like this one is a simple yet effective way to ensure your vehicle's oil system remains leak-free. It is a small component that plays a significant role in protecting your engine from damage caused by low oil levels or contamination. This washer is designed for a precise fit, ensuring it works seamlessly with your TOYOTA's oil drain plug and oil pan. Regular replacement, typically during an oil change, is recommended to maintain optimal performance and prevent costly repairs.
