Remove the crankshaft pulley from the engine. Carefully pry the seal out of the cover with a seal removal tool or a large screwdriver, being careful not to nick or gouge the seal bore or the crankshaft. 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 (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 - but don't overdo it! 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 a large 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.

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.

The timing belt should be removed.

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

Install the vibration damper bolt, and complete the installation in reverse order, followed by refilling the cooling system.

Use the proper puller, but 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. 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.

The installation depth and facing direction of the old seal should be noted, as the new one must be installed in the same way.

Several special tools are required for this procedure.

Install the new oil seal housing onto the crankshaft using a special guide tool.

An alternative method involves drilling small holes on each side of the seal and inserting self-tapping screws, which can then be used with pliers to pull the seal out without prying.

The old rear main oil seal can be removed by prying it out of the housing with a screwdriver, taking care not to damage the crankshaft surface.

The rear main seal and housing are serviced as one complete assembly.

Use a two-bolt puller to take off the crankshaft sprocket by threading the bolts into the holes in the sprocket.

Drive the seal into the bore using a seal driver or a large socket and hammer until it is completely seated, ensuring the selected socket matches the outside diameter of the seal.

After cleaning the housing thoroughly, a thin coat of engine oil should be applied to the new seal. The new seal must be set squarely into the recess of the housing before pressing it into place with a piece of wood and a hammer.

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.

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 old rear main oil seal can be removed by prying it out of the housing with a screwdriver, taking care not to damage the crankshaft surface.

Position the new seal in the bore with the seal lip (usually the side with the spring) facing IN (toward the engine).

Position the new seal with the lip facing inward, applying a small amount of oil to the outer edge for easier installation.

Position the new seal in the bore with the seal lip, typically the side with the spring, facing inward toward the engine.

The seal can be removed by prying it out of the engine block with a screwdriver.

The new seal should be installed along with the installation pilot tool onto the crankshaft. Once in place, the pilot can be removed. A seal installation tool, a large socket, or a steel plate and a hammer can be used to drive the seal evenly into place, ensuring it doesn't tilt.

The pulley hub should be lubricated with clean engine oil before installing the pulley. This will help with smooth operation.

The inner lip of the new seal should be lubricated with engine oil and then driven in using a seal driver or a large deep socket and a hammer.

Disconnect the cable from the negative terminal of the battery.

To replace this seal, the transmission and flywheel/driveplate need to be removed.

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.

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.

Drain the coolant, remove the upper radiator hose, and remove the fan shroud.

The rear main oil seal has been incorporated into the seal retainer and must be replaced as a unit.

Slide the retainer and seal off the end of the crankshaft.

The seal can be removed by prying it out of the engine block with a screwdriver.

Drain the coolant, remove the upper radiator hose, and remove the fan shroud.

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.

Before removing the flywheel or driveplate, it is important to mark its position.

Place the cover on wooden blocks. Apply stud and bearing mount compound to the outside of the new seal, then tap it into place using a large socket or a seal installation tool. Install the alignment pilot tool into the seal. Apply a bead of RTV sealant to the sealing surface of the cover.

The initial steps are to disconnect the cables from the negative terminals of the batteries and remove the drivebelt. Drain a sufficient amount of coolant into a clean container. Remove the upper radiator hose, detach the coolant reservoir hose from the radiator, and remove the windshield washer bottle.

The old rear main oil seal can be removed by prying it out of the housing with a screwdriver, taking care not to damage the crankshaft surface.

The final step is to reverse the removal process to complete the installation.

Carefully pry the cover from the front of the engine, taking care to avoid damaging the sealing surface. Place the cover on wooden blocks and use a hammer and punch to drive the seal out from the rear. Carefully inspect the damper for signs of fluid leakage.

Apply a 1/4-inch bead of RTV sealant where the lower corners of the seal retainer meet the oil pan.

Before installing the pulley, it is important to check the surface on the pulley hub that the oil seal rides on. If it is grooved, the pulley should be replaced.

The final step is to reverse the removal process to complete the installation.

Clean the engine block, oil pan, and crankshaft.

The seal bore in the block should be thoroughly cleaned with a shop towel, removing all traces of oil and dirt.

The initial steps are to disconnect the cables from the negative terminals of the batteries and remove the drivebelt. Drain a sufficient amount of coolant into a clean container. Remove the upper radiator hose, detach the coolant reservoir hose from the radiator, and remove the windshield washer bottle.

Disconnect the cable from the negative terminal of the battery.
