2. Remove the oil pan by unscrewing bolts and carefully prying it off the engine block.
3. Clean the old gasket material from the oil pan and engine block.
4. Install a new gasket and reattach the oil pan, torquing bolts to the specified torque (usually around 10-15 lb-ft).

3. Check and Replace Seals

Front and Rear Crankshaft Seal Replacement
1. Remove the drive belts and crankshaft pulley.
2. Use a seal puller to remove the old seal.
3. Clean the seal bore and install the new seal, ensuring it is seated properly.
