Tools Required: Socket set, torque wrench, seal puller, seal installer
Remove any components obstructing access to the crankshaft seal (e.g., timing belt or pulley).
Use the seal puller to carefully remove the old crankshaft seal.
Clean the sealing surface on the engine block.
Apply a small amount of engine oil to the new seal's lip.
Use the seal installer to correctly position the new crankshaft seal.

4. Inspect and Replace Timing Cover Gasket (if necessary)

Tools Required: Gasket scraper, RTV silicone sealant, torque wrench
Remove the timing cover bolts and carefully detach the timing cover.
Scrape off the old gasket material from the engine block and timing cover.
Apply a thin layer of RTV silicone sealant on both sides of the new gasket.
Reinstall the timing cover and torque bolts to manufacturer specifications.
