    NOTE: Do not reuse the crankshaft pulley bolt.
  7. Install a new crankshaft pulley bolt. Use the Crankshaft Damper Holding Tool and a suitable 1/2-in drive hand tool to hold the crankshaft pulley, tighten the crankshaft pulley bolt in 2 stages:
    • Stage 1: Tighten to 100 Nm (74 lb-ft).
    • Stage 2: Tighten an additional 90 degrees.
