The oil strainer (also known as the oil filter or oil screen) is a critical component of the engine lubrication system. It filters metal debris, carbon particles, and contaminants from the engine oil, ensuring that clean oil flows to all lubricated engine components, protecting internal precision parts from wear. This kit contains all components of the oil strainer cap assembly, allowing direct replacement of aging or damaged original parts to restore lubrication system filtration performance and extend engine service life. Regular replacement of the oil strainer is an essential part of engine maintenance.

🔧 Installation & Maintenance Guide

1. Ensure the engine is cool and the vehicle is on level ground before starting.
2. When changing oil, drain the old oil first, then remove the oil filter cap.
3. Remove the old strainer and spring, and clean the cap and mounting surface, removing any old seal residue.
4. Install the new seal, ensuring it is properly seated in the groove without twisting.
5. Place the new spring inside the filter cap, then insert the new strainer, ensuring correct orientation.
6. Install the filter cap assembly onto the engine, hand-tighten initially, then torque to specification (approximately 15-25 N·m).
7. Add new oil to the correct level, start the engine, and check for leaks around the filter cap.
8. It is recommended to inspect and clean the strainer every 2-3 oil changes; replace it if damaged or severely clogged.
