    Q:
    How to remove and install the crankshaft pulley and Crankshaft Seal in 3.6L V6 engine on Buick Enclave? Posted by Ghias R.
    A:
    Remove the crankshaft pulley. Note how the seal is installed-the new one must be installed to the same depth and facing the same way. Carefully pry the seal out of the cover. If you don't have a seal removal tool, thread a self tapping screw partially into the seal, then use pliers as a lever to pull it from the engine. If the seal is being replaced with the timing chain cover removed, support the cover on top of two blocks of wood and drive the seal out from the rear with a hammer and punch. Caution: Be careful not to scratch, gouge or distort the area that the seal fits into or a leak will develop. Installation: Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip (spring side) facing IN. Drive the seal into place with a seal driver or a large socket and a hammer. Make sure the seal enters the bore squarely and stop when the front face is at the proper depth. Note: Don't let oil get on the rubber part of the seal or on the part of the crankshaft pulley that touches the seal. The seal must be installed dry. Check the surface on the pulley hub that the seal rides on. If the surface has been grooved from long-time contact with the seal, the pulley should be replaced with a new one. Lubricate only the inside of the pulley hub with clean engine oil and install the crankshaft pulley. The remainder of installation is the reverse of removal.
