Remove the transmission and all other components necessary, such as the clutch and pressure plate, to access the oil seal in the back of the engine. Next, remove the flywheel. Use a small punch to create two holes on opposite sides of the seal and install small sheet metal screws in these holes. Pry on the screws with two large screwdrivers until the seal is removed from the engine, taking care to place small blocks of wood against the block to provide a fulcrum point for prying, while avoiding any scratches or damage to the crankshaft oil seal surface. Apply a thin film of engine oil to the outer edge of the new seal, the seal bore in the block, and the seal lips. Position the seal on a special tool, available at most auto parts stores, and then place the tool and seal at the rear of the engine, installing the seal with the spring side toward the engine and alternating the tightening of the bolts to seat the seal in the block. If a special seal installer is not available, work the seal into place and gently tap it into the bore with a soft-face hammer, using the drive end of a socket extension or another blunt, smooth object to ease the lip of the seal over the end of the crankshaft. The remainder of the installation follows the reverse of the removal procedure.

Check the seal bore and crankshaft, as well as the seal contact surface on the crankshaft pulley, for nicks or burrs.

Inspect the seal bore, crankshaft, and the seal contact surface on the vibration damper for any damage.

Apply a small amount of oil to the outer edge of the seal.

Start by removing the fan shroud, fan/clutch assembly, and drivebelts. Extract the bolt from the front of the crankshaft and use a puller to detach the vibration damper.

Reinstall the engine rear cover plate, driveplate, and transmission. Complete the remaining steps in reverse, check the oil level, run the engine, and inspect for oil leaks.

If installing a new vibration damper, ensure proper balance pin alignment and apply clean engine oil and RTV sealant. Install the damper on the crankshaft, aligning the keyway, and secure the remaining components.

Disconnect the negative cable from the battery terminal.

The front crankshaft oil seal can be removed using a special tool or, on most engines, with a small chisel and hammer, being cautious not to damage the cover or the seal bore. Apply penetrating oil if needed.

Repeat the procedure to install the remaining seal half in the rear main bearing cap. On V8 engines, leave the opposite end of the seal protruding from the cap the same distance the block seal is protruding from the block. On 2.3L and 3.8L engines, position both ends flush with the bearing cap.

Unbolt and remove the pulley.

Clean the bore to remove any old seal material and corrosion. Support the cover on blocks of wood and position the new seal in the bore with the open end of the seal facing IN. A small amount of oil applied to the outer edge of the new seal will make installation easier.

Coat the seal lip and crankshaft surface with engine oil.

Remove the pressure plate, disc, and clutch assembly.

Install the oil seal retainer onto the crankshaft, working the seal onto the crankshaft with a smooth object. Tighten the retainer bolts to the specified torque.

Remove the fan assembly and the shroud.

Remove the fan/clutch assembly and the fan shroud (Chapter 3).

Press the new seal into position using special tool T81P-6701-A or equivalent. If the special tool is unavailable, you may be able to tap the seal into position squarely with a blunt punch and a hammer. Be very careful not to damage the seal or crankshaft. As you install the seal, work the seal lip over the end of the crankshaft with the rounded end of a socket extension or a similar tool.

Install the belt sprocket and the pulley to the crankshaft.
