You can Select Your Vehicle to check if 12279-ED000 fits your vehicle.

Loosen the right front wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the right front wheel. Next, take out the right inner wheel well and the drivebelts. Remove the crankshaft pulley bolt, and if necessary, have an assistant hold the crankshaft from turning by wedging a screwdriver in the flywheel driveplate teeth through the access hole. Use a puller to remove the pulley from the crankshaft, ensuring the proper adapter is used on the end of the crankshaft to prevent damage, and that the jaws of the puller are secured to the hub of the pulley. To pry out the seal, use a seal-puller tool or a screwdriver with tape on the tip, taking care not to damage the seal bore or scratch the crankshaft snout. Clean the bore in the timing chain cover and coat the outer edge of the new seal with engine oil or multi-purpose grease, also lubricating the seal lips. Carefully drive the new seal into place using a seal driver or a socket with a slightly smaller outside diameter than the seal, ensuring it is installed squarely and to the same depth as the original, while checking that the garter spring remains in place. Remember that the oil seal lip faces the engine and the dust seal lip faces the pulley. Reinstall the crankshaft pulley and drivebelt, using a pulley installation tool for proper placement, and tighten the crankshaft pulley bolt to the specified torque. Finally, run the engine and check for oil leaks.

Reconnect the battery and perform the necessary re-learn procedures.

Ease the sealing lip over the crankshaft shoulder and press the seal evenly into its recess.

Use grips or pliers to pull out the oil seal, taking care not to drill into anything other than the seal if using a self-tapping screw.

If the Nissan tool is unavailable, a similar tool can be fabricated.
