  How to remove and install a front crankshaft seal for the 2010 Toyota Prius?

  A:

  Remove the crankshaft pulley and note how the seal is installed, ensuring the new one is positioned to the same depth and orientation. Carefully pry the oil seal out of the cover using a seal puller or a large screwdriver, taking care not to damage the crankshaft. To facilitate removal, cut the lip of the seal with a utility knife, being cautious not to distort the cover or scratch the crankshaft; wrapping electrician's tape around the screwdriver tip can help prevent damage. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal and install it in the cover with the lip facing inward. Drive the seal into place using a seal driver or a large socket and hammer, ensuring it enters the bore squarely and stops at the correct depth. Check the surface on the pulley hub for any grooves caused by long-term contact with the seal, and replace the pulley if necessary. Lubricate the pulley hub with clean engine oil and reinstall the crankshaft pulley, then install and tighten the retaining bolt. The remainder of the installation follows the reverse order of removal.
