  A:

  Disconnect the negative cable from the battery, raise the front of the vehicle, remove the right front wheel, and secure the vehicle on jackstands. Remove the drivebelts, then take off the inner splash shield from the right fenderwell. 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; a chain-type wrench may be used if an old drivebelt is wrapped around the crankshaft pulley first. Wedge a prybar or two screwdrivers behind the crankshaft pulley and carefully pry it off; if it is difficult to remove, use a bolt-type puller. Remove the timing belt covers and timing belt, then carefully remove the crankshaft sprocket with a prybar or two screwdrivers, taking care not to damage the oil pump body. If the sprocket cannot be pried off, drill and tap two holes into the face of the sprocket and use a bolt-type puller to remove it, ensuring not to reuse a drilled sprocket. Remove the timing belt guide, noting the side facing out, and carefully pry the oil seal out with a screwdriver, avoiding any damage to the crankshaft. Before installation, apply a thin coat of multi-purpose grease to the inside of the seal. Fabricate a seal installation tool using a short length of pipe, a long bolt, and a large washer, then press the oil seal into position with the tool, ensuring not to damage the seal. Install the inner timing belt guide onto the nose of the crankshaft, ensuring the Woodruff key is in place, and apply a thin coat of assembly lube to the inside of the timing belt sprocket before sliding it onto the crankshaft. Installation of the remaining components follows the reverse order of removal, tightening all bolts to the specified torque.
