  Q: How to remove and install a crankshaft pulley on 3.5L V6 Nissan Frontier?

  A: Disconnect the cable from the negative terminal of the battery. Block the rear wheels and set the parking brake. Raise the front of the vehicle and support it securely on jackstands. Remove the lower splash shield if equipped. Remove the engine cooling fan and the fan shroud. Remove the drivebelts. Remove the crankshaft position sensor from the front liming chain cover. Use a strap wrench around the crankshaft pulley to hold it while using a breaker bar and socket to remove the crankshaft pulley center bolt. Use a strap wrench to hold the crankshaft pulley while removing the center bolt. A chain-type wrench may be used if you wrap a section of old drivebelt around the crankshaft pulley first. Wedge a prybar or two screwdrivers behind the crankshaft pulley and carefully pry it off the crankshaft. If the pulley is difficult to remove, place a two jaw type puller into the openings in the center of the hub and pull it off. Do not place the puller jaws around the outside of the crankshaft pulley or damage to the pulley will occur. Depending on the type of puller you have it may also be necessary to remove the radiator to gain sufficient clearance to use the puller. To install the crankshaft pulley align the pulley groove with the key on the crankshaft and slide the pulley onto the crankshaft. Install the crankshaft pulley retaining bolt and tighten it to the specific torque. The remainder of installation is the reverse of the removal.
