Retainer bolt in center of front crankshaft pulley/vibration damper - used on all 2002, 2003, 2004, 2005 and early 2006 models.
The torque spec that has been provided to us is 240 ft/lbs or 325 Nm, plus 90 degrees.
THIS BOLT IS MARKED 10.9 ON THE HEAD.
The later crankshaft (from mid 2006 and later) has a single groove and uses both a different woodruff key and a different center bolt (MARKED 1150). If you have a 2006 model, check your bolt first, before ordering. See this second bolt, shown below.

Always replace this bolt when changing the crankshaft pulley/vibration damper. Do not reuse your old bolt, as it is a stretch bolt and is to be torqued to spec, once and only once, and discarded once removed.
