How do you change front crank seal on Saturn 2.22000?

To change the front crank seal on a Saturn 2.2L engine, first, disconnect the battery and remove the serpentine belt. Then, remove the crankshaft pulley using a puller, and clean the area around the crankshaft. Carefully pry out the old seal using a seal puller or flat tool, and install the new seal by tapping it gently into place, ensuring it's flush with the timing cover. Finally, reassemble the pulley and belt, reconnect the battery, and check for leaks.
