2002 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the rear crankshaft seal on 2002 Buick Park Avenue?

  A: The Crankshaft rear oil seal replacement requires beginning with engine Flywheel removal to check the seal leak while avoiding damage to both Crankshaft od surface and chamfer with a flat-bladed tool. Insert a small flat-bladed tool parallel to the dust lip entrance to pry the Crankshaft rear oil seal until the tool moves towards the Crankshaft end by repeating this action until the oil seal comes loose. When inspecting the bore id you should both fix any possible issues with the Crankshaft rear oil seal housing and determine whether to replace the Crankshaft rear oil seal housing or not. Also finalize whether to repair or replace the contact surface of the Crankshaft. Before setting the Crankshaft rear oil seal into position apply engine oil to its interior surface and exterior diameter. After that position the new seal over the mandrel until it reaches the stop against the j 38196 rear Crankshaft Seal installer (J 38196) collar. You should either hand tighten the bolts of j 38196 to 5 nm (54 inch lbs.) or use your hand force to attach it to the Crankshaft. Turn the t-handle on j 38196 to push the seal into the bore until the collar tightly contacts the case to achieve proper seating. Adjust the t-handle until it stops when positioning the collar before installing another new Crankshaft rear oil seal. After finishing this step remove the attaching screws. Reinstallation of the engine Flywheel should be followed by fluid level inspection and leak checks.
