2. Identify and Repair Oil Leaks

Sub-step 1: If leaks are found at the oil filter, remove the old oil filter using the oil filter wrench and replace it with a new one. Ensure it is properly tightened to the manufacturer's specifications (usually hand-tight plus a quarter turn).
Sub-step 2: If leaks are found at gaskets or seals, use a socket set to remove the affected component (e.g., valve cover or oil pan). Replace the gasket or seal with a new one, ensuring proper alignment.

3. Check and Replace Engine Oil

Sub-step 1: Using a socket set, remove the oil drain plug to drain the old oil into a pan.
Sub-step 2: Replace the oil drain plug and tighten it to the manufacturer’s specifications (typically around 20-25 ft-lbs).
Sub-step 3: Fill the engine with the appropriate grade of oil as specified in the owner’s manual (typically 0W-20 for Honda engines).

4. Monitor Engine Temperature

Sub-step 1: Reconnect the battery and start the engine.
Sub-step 2: Monitor the engine temperature and check for leaks while the engine is running; address any new leaks immediately.
