Lift the transaxle out of the car and then the driveplate or flywheel has to be pulled out. Whether it is a slotted or a solid Crankshaft Seal, pry it out from the rear of the engine using a seal removal tool or a flat-end screwdriver, risking the crankshaft or the seal bore. Afterwards, clean the seal bore area within the block with a shop towel to ensure that the area is free of any oil or dirt deposits. Apply oil on the OD of the seal and place it over the extremity of the crankshaft with the lip facing the engine. Ideally, a seal installation tool can be used to push the new seal back into its proper position while it is noted that a small oil drain in the separator must be in the lowest position. If the proper tool is not available, the big socket must be used to insert the new seal gently into the seal bore in a way they are perpendicular to the surface of the engine block and lies flush with the outer perimeter of the block. Lastly, bolt on the driveplate/flywheel, and then the transaxle.

See Chapter 2, Part A for this procedure.

Lubricate the outside diameter of the seal and install it over the end of the crankshaft, ensuring the lip of the seal points toward the engine. Preferably, use a seal installation tool to press the new seal back into place. Note that there is a small oil drain in the separator that must be in the lowest position. If the proper seal installation tool is unavailable, use a large socket to carefully drive the new seal squarely into the seal bore and flush with the edge of the engine block.

Lubricate the pulley hub with clean engine oil.

The remainder of the installation is the reverse of the removal process.

Clean the bore in the engine and coat the outer edge of the new seal with engine oil or multi-purpose grease. Apply the same grease to the seal lip.

Reinstall the components removed for access to the seal and run the engine to check for oil leaks at the front seal.
