You can Select Your Vehicle to check if 90311-A0027 fits your vehicle.

Lubricate the outside diameter of the seal and install the seal over the end of the crankshaft, making sure the lip of the seal points toward the engine.

Remove the crankshaft pulley. Carefully pry the seal out of the timing chain cover with a screwdriver or seal removal tool, being careful not to scratch the crankshaft. If you use a screwdriver, wrap tape around the tip to avoid scratching the housing bore or damaging the crankshaft, as this could cause the new seal to leak. Clean the bore in the timing chain cover and coat the lip and the outer edge of the seal with engine oil or multi-purpose grease. Using a seal driver or a socket with an outside diameter slightly smaller than the outside diameter of the seal, carefully drive the new seal into place with a hammer. Lubricate the seal lip and drive the new crankshaft seal into place with a large socket or piece of pipe and a hammer. Ensure it's installed squarely and driven in flush with the surface of the timing chain cover. Check the seal after installation to make sure the spring didn't pop out of place. Reinstall the crankshaft pulley, tightening the bolt to the torque. Run the engine and check for oil leaks at the front seal.

Wrap tape around the tip of the screwdriver to avoid scratching the housing bore or damaging the crankshaft, as this could cause the new seal to leak.

The first step is to remove the engine/transmission assembly from the vehicle.

Install the flywheel or driveplate.

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

The new seal should be evenly driven into the container using a wood block or a section of pipe slightly smaller in diameter than the outside diameter of the seal.

The new seal can be driven into place using a seal driver or a large socket and a hammer. It is important to ensure that the seal enters the bore squarely and stops when the front face is at the proper depth.
