Tools and Materials:
- Metric Socket Wrench
- 10mm and 12mm Socket
- Oil Drain Pan
- Engine Oil (Consult your owner's manual for the correct type and amount)
- Oil Filter Replacement (Optional, if needed)
Procedure:
1. Prepare the Engine: Ensure that the engine is turned off and has cooled down to avoid any burn risks. Engage the parking brake and position your oil drain pan underneath the vehicle.
2. Locate the Oil Drain Plug: On the bottom of the engine oil pan, you'll find a 17mm drain plug. Position the oil drain pan directly underneath this plug.
3. Drain the Oil: Use the 17mm socket to loosen and remove the oil drain plug. Allow the old oil to drain completely into the oil pan. Once the oil has drained, reinsert the drain plug and tighten securely.
4. Remove the Oil Filter (Optional): If you intend to change the oil filter at the same time, you can remove the old oil filter now. Use the 24mm socket to loosen and remove the oil filter. Apply a thin layer of new engine oil to the gasket of the new oil filter before screwing it back in place.
5. Locate the Bleeder Screws: On the top of the engine, near the valve cover, you'll find the hydraulic lifter bleeder screws. These are usually located along the sides of the camshaft.
6. Prepare for Bleeding: Place an oil pan or rag underneath the bleeder screws to catch any escaping oil.
7. Bleed the Lifters: Use the 10mm socket to loosen and remove one of the bleeder screws. Allow the oil to escape until it stops completely. This indicates that the air has been released. Tighten the bleeder screw securely.
8. Repeat for All Bleeder Screws: Repeat the bleeding process for each bleeder screw, ensuring you allow all of the air to escape before tightening the screw.
9. Add Engine Oil: Remove the oil filler cap on top of the engine and add the recommended amount of new engine oil. Refer to your owner's manual for the accurate amount and oil type.
10. Check for Leaks: Start the engine and let it run for a few minutes. Check underneath the vehicle for any signs of oil leaks, especially around the drain plug and oil filter. If you notice any leaks, tighten the drain plug or oil filter until the leak stops.
11. Check the Engine Oil Level: Use the engine oil dipstick to ensure the oil level is between the "Full" and "Add" marks on the dipstick.
Note: Bleeding the hydraulic lifters can help reduce engine noise and improve valve train performance. However, if the noise persists or you encounter difficulties, it's best to consult a certified mechanic for further diagnosis and repair.
