• Q: How to replace the rear crankshaft seal on 2001 Cadillac Seville?

  A: The replacement of the crankshaft rear oil seal requires Flywheel removal. You should utilize the crankshaft rear oil seal remover (J 42841) which goes onto the crankshaft before securing it with retaining bolts. Use a variable speed drill to drive eight one-inch self-drilling screws through the guide holes of the removal tool into the seal surface until drill speed reaches a minimal level as threads engage. The j 42841 requires the center screw after bolting removal and tightening it through the tool to displace the seal assembly from the crankshaft. A leak-free operation requires first clearing the drain channel before fitting the new crankshaft rear oil seal. Use wire along with an unbound plastic tie-wrap to cleanse debris from the crankshaft rear oil seal drain opening. Apply engine oil with gm p/n 12345501 or equivalent to the outer area around the crankshaft rear oil seal in the cylinder block. Use caution to avoid contaminating the green coating on the inside of the new seal. Apply clean engine oil to the new crankshaft rear oil seal's outer rubber surface after cleaning both the Flywheel flange surface with a lint-free cloth and the outer diameter of the drain. Use the crankshaft rear oil seal installer's (J 42842) center bolt to achieve a one-half inch protrusion of the center hub before mounting the j 42842 onto the crankshaft and threading its three bolts into the crankshaft flange until j 42842 achieves firm contact. Install the crankshaft rear oil seal through center bolt torquing until j 42842 touches crankcase bottom then loosen center bolt for pressure relief before removing the three mounting bolts. Check the crankshaft flange for proper depth installation of the j 42842 seal around its entire circumference. Perform additional installations if necessary before removing the seal. Finally, reinstall the Flywheel.
