Disconnect the cable from the negative terminal of the battery. Remove the upper radiator crossmember, the cooling fan assembly and the radiator. Remove the engine splash shield. Remove the drivebelts and position the belt tensioner away from the crankshaft pulley. Use a strap wrench around the crankshaft pulley to hold it while using a breaker bar and socket to remove the crankshaft pulley center bolt. Pull the damper off the crankshaft with a puller. The jaws of the puller must only contact the hub of the pulley not the outer ring. A spacer should be placed against the end to the crank-shaft nose or a long Allen-head bolt should be inserted into the crankshaft nose for the puller's tapered tip to push against to prevent damage to the crankshaft threads. Check the surface on the pulley hub that the oil seal rides on. If the surface has been grooved from long-time contact with the seal, a press-on sleeve may be available to renew the sealing surface. This sleeve is pressed into place with a hammer and a block of wood and is commonly available at auto parts stores for various applications. Lubricate the pulley hub with clean engine oil and reinstall the crankshaft pulley. Use a vibration damper installation tool to press the pulley onto the crankshaft. Install the crankshaft pulley retaining bolt and tighten it to the torque. The remainder of installation is the reverse of the removal.

Disconnect the cable from the negative terminal of the battery. Remove the engine drivebelt. Drain the coolant, remove the upper radiator hose, and remove the engine cooling fan. Remove the large vibration damper-to-crankshaft bolt. To keep the crankshaft from turning, install a chain wrench or strap wrench around the circumference of the pulley. Be sure to use a piece of rubber under the chain wrench to protect the vibration damper from nicks or gouges. Using the proper puller, detach the vibration damper. Do not use a puller with jaws that grip the outer edge of the pulley. The puller must be the type that utilizes bolts or arms to apply force to the pulley hub only. Also, the puller screw must not contact the threads in the nose of the crankshaft; it must use an adapter that allows the puller screw to apply force to the end of the crankshaft nose or a spacer must be inserted into the nose of the crankshaft to protect the threads. If the seal is being removed while the cover is still attached to the engine block, carefully pry the seal out of the cover with a seal removal tool or a large screwdriver. Be careful not to scratch, gouge, or distort the area that the seal fits into or an oil leak will develop. Clean the bore to remove any old seal material and corrosion. Position the new seal in the bore with the seal lip facing IN (toward the engine). A small amount of oil applied to the outer edge of the new seal will make installation easier. Drive the seal into the bore with a seal driver or a large socket and hammer until it's completely seated. Check the surface of the damper that the oil seal rides on. If the surface has been grooved from long-time contact with the seal, replace the vibration damper. Lubricate the seal lips with engine oil and reinstall the vibration damper, aligning the Woodruff key on the nose of the crankshaft with the keyway in the damper hub. Use a special installation tool to press the vibration damper onto the crankshaft. Install the vibration damper bolt and tighten it to the torque. The remainder of installation is the reverse of the removal process. Refill the cooling system.
