• Q: How to replace the rear crankshaft seal on 2002 Cadillac Seville?

  A: Begin by taking out the Flywheel before replacing the crankshaft rear oil seal. The crankshaft rear oil seal remover (J 42841) needs to be placed on the crankshaft then fastened using retaining bolts. A variable speed drill motor working in conjunction with a socket adapter lets you thread eight one-inch self-drilling screws through the seal using the guide holes on the removal tool but requires slower drill speed once the screws begin to tighten. Tighten the center screw of the j 42841 tool to pull the seal assembly from the crankshaft while keeping the retaining bolts removed. Liquid leaks should be avoided during new crankshaft rear oil seal installation by clearing the drain opening first. Gather any remnants of debris from the crankshaft rear oil seal drain by using wire or an unbound plastic tie-wrap. Put gm p/n 12345501 engine oil (Canadian P/N 992704 equivalent) on the cylinder block crankshaft rear oil seal friction area except around the space where the seal touches the crankshaft. Keep the inner diameter green coating free from contamination. Clean the Flywheel flange's outer diameter with a lint-free cloth before applying clean engine oil to the rubber surface of the crankshaft rear oil seal. Mount the crankshaft rear oil seal installer (J 42842) onto the crankshaft and adjust its center bolt so the central hub protrudes one-half inch beyond the outer plate. Prescribe the crankshaft rear oil seal installation through center bolt torque until j 42842 reaches crankcase bottom then reduce center bolt torque and remove all mounting bolts. Inspect the installation depth of the crankshaft rear oil seal around the entire circumference before reinstalling j 42842 onto the crankshaft flange if necessary. Finally, reinstall the Flywheel.
