Disconnect the cable from the negative battery terminal. Raise the vehicle and support it securely on jackstands, then remove the wheel and the splash shield from below the engine compartment. Loosen the crankshaft pulley bolt using a special tool that engages with the recessed hex in the pulley opening to prevent the crankshaft from turning while unscrewing the bolt. If a special tool is unavailable, remove the flywheel/driveplate inspection cover and wedge a screwdriver into the starter ring gear teeth. Slip the pulley off the crankshaft. Carefully pry the seal out of the timing chain cover with a seal removal tool or a screwdriver, taking care not to scratch the seal bore or damage the crankshaft, as damage will cause the new seal to leak. Clean the bore in the seal housing and coat the outer edge of the new seal with engine oil or multi-purpose grease. Using a seal driver or a socket with an outside diameter slightly smaller than that of the seal, carefully drive the seal into place with a hammer; if a socket is not available, a short section of a large diameter pipe will suffice. After installation, check the seal to ensure the spring did not pop out. Lubricate the lip of the seal with a thin film of engine oil or multi-purpose grease, and lubricate the pulley bolt threads and the surface between the washer and bolt head with clean engine oil before installing the crankshaft pulley and tightening it to the specified torque. The remainder of the installation follows the reverse order of removal. Finally, run the engine and check for leaks.

Apply a film of clean oil to the crankshaft seal journal and the lip of the new seal.
