Solution

1. Preparation

Gather tools and materials including a socket set, oil catch pan, replacement oil and filter, and rags.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Replace Oil Filter

Sub-steps:
1. Place an oil catch pan under the oil filter.
2. Remove the old oil filter using an oil filter wrench.
3. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
4. Install the new oil filter by hand until snug, then tighten according to the manufacturer's specifications (typically 3/4 to 1 full turn after the gasket makes contact).

3. Inspect and Replace Front Crankshaft Seal (if necessary)

Sub-steps:
1. Remove the serpentine belt from the front of the engine.
2. Remove any components obstructing access to the crankshaft pulley (may include the alternator or air conditioning compressor).
3. Remove the crankshaft pulley using a puller tool.
4. Carefully pry out the old front crankshaft seal using a seal puller.
5. Lubricate the new seal with engine oil and press it into place using a seal driver or a suitable tool.
6. Reinstall the crankshaft pulley and tighten it to the specified torque (typically around 50-70 ft-lbs).
7. Reinstall the serpentine belt and any components removed.

4. Add Oil and Check Levels

Sub-steps:
1. Add the appropriate type and amount of engine oil to the engine (consult the owner’s manual for specifications).
2. Start the engine and allow it to idle for a few minutes.
3. Check for any leaks and monitor the oil pressure.
