The crankshaft pulley must be taken off the engine. Removing the seal can be done with the help of a seal removal tool or a large screwdriver; see to it that the seal bore and the crankshaft are not damaged when doing it. It is also important not to rub, scratch, gouge or distort the region that forms the seal for this may cause an oil leakage. Scrub the bore area with a view of removing old seal material plus any rust. Align the new seal within the bore with it's seal lip which is often the side with incorporated spring facing the inner side of the engine. During installation of the new seal it will be easier if a little oil is applied to the outer edges of the seal. Force the seal into the bore using a seal driver or a large socket and hammer until the seal is flush to the cover flange, thus the socket should be of the same size as the outside diameter of the seal and the new seal should be forced right to the bottom. Grease the seal lips and replace the crankshaft pulley. To do this reverse the process you used to remove the oil, complete the installation process and run the engine for a while checking if there is any leakage of oil.

Remove the crankshaft pulley from the engine. Carefully pry the seal out of the cover with a seal removal tool or a large screwdriver. Pry the seal out very carefully with a seal removal tool or screwdriver, being careful not to nick or gouge the seal bore or the crankshaft. Do not 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 (usually the side with the spring) 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. Use a seal driver or large-diameter socket to drive the new seal into the cover. Select a socket that's the same outside diameter as the seal and make sure the new seal is pressed into place until it bottoms against the cover flange. Lubricate the seal lips with engine oil and reinstall the crankshaft pulley. The remainder of installation is the reverse of removal. Run the engine and check for oil leaks.

Use a proper puller, ensuring it grips the hub only and does not contact the threads in the crankshaft nose.

Remove the engine drivebelt.

These models utilize a one-piece rear main seal positioned between the engine block and the lower main bearing cap assembly, often called a "bed plate".

The seal lip must be lubricated with clean engine oil before installing the seal over the end of the crankshaft, ensuring the lip points toward the engine.

Push it squarely into place, making sure the dowels in the seal retainer engage the locating holes in the engine block.

Push it squarely into place, making sure the dowels in the seal retainer engage the locating holes in the engine block.

If the crankshaft is damaged, the new seal will leak.

If the crankshaft is worn at the seal contact area, a crankshaft sleeve should be installed over it.

Remove the mounting bolts, then remove the crankshaft damper. Remove the power steering pump and the drivebelt tensioner. Remove the gear cover mounting bolts.

Use a seal driver or large-diameter socket that has the same outside diameter as the seal.

The crankshaft pulley can be removed by using a screwdriver or hook tool to carefully pry out the seal. Alternatively, small holes can be drilled on each side of the seal and self-tapping screws can be used to pull it out. If the timing chain cover is removed, the seal can be driven out from the backside with a hammer and punch.

The remainder of the installation is the reverse of removal. Refill the cooling system.

After removing the rear seal, thoroughly clean the seal bore and the crankshaft, ensuring all traces of oil are wiped off.

Before installing a new seal, it is important to apply clean engine oil or multi-purpose grease to the outer edge of the seal. This will help with proper lubrication.

The new seal should be installed over the end of the crankshaft, making sure the lip of the seal points toward the engine.

Be cautious not to use a puller with jaws that grip the outer edge of the pulley and ensure the puller screw does not contact the threads in the nose of the crankshaft.

Thoroughly clean the new seal and the seal bore in the cover. Remove any old sealer. Straighten the cover if necessary by tapping the sealing surface on a flat area with a hammer. It must be flat before installation. Clean the sealing surfaces of the cover and the block with brake system cleaner when finished. Check the crankcase snout for nicks or burrs. Dress any imperfections with a small file.
