You can Select Your Vehicle to check if 5086853AA fits your vehicle.

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.

These types of models feature a single-piece rear Crankshaft Seal that is packed between the engine block and the lower main bearing cap assembly. This requires taking out the transmission as well as flywheel/drive plate for having it done. The screwdriver will remove this seal from the engine block, but be careful not to score the crankshaft surface. When there is damage at crankshaft then new seal will leak. Put tape around the lip of screwdriver blade to avoid damaging it. Take clean shop towel and carefully wipe off anything remaining on seal bore in block. Remove oil and dirt completely. Carefully place the seal over end of crankshaft after lubricating its lip with fresh engine oil. Make sure the lip of the seal points toward the engine. Normally, use a special tool designed for installation of this kind (available in most car parts shops) that should be applied on pressing back into places such new seals if necessary. Make sure that the new seals are driven squarely into their bores flush with rear face of engine block. Rest of job involves putting everything back together again according to removal process.

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

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

The remainder of the installation is the reverse of removal.

Carefully pry the seal out with a seal removal tool or a large screwdriver.

Run the engine and check for oil leaks.

Raise the vehicle and support it securely on jackstands.

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.

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.

Remove the viscous fan and drive assembly, then remove the fan shroud and fan. Remove the fan support from the engine.

Make sure the plastic installation sleeve is in place.

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

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

The first step is to remove the transmission and the clutch if working with a manual transmission.

During the installation of the new seal, it is important not to use oil on the seal lip or crankshaft. Both surfaces must be clean and dry to prevent leaks. Soapy water can be used as an assembly lubricant if necessary.

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

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

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

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

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.

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.

Avoid scratching, gouging, or distorting the area that the seal fits into to prevent an oil leak from developing.

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

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

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

Disconnect the cable from the negative terminal of the battery.
