  8.  
  9. Remove the timing belt from the camshaft timing pulley, as follows:
    1. If reusing the belt, place matchmarks on the timing belt and the camshaft pulley. Loosen the mount bolt of the No. 1 idler pulley and position the pulley toward the left as far as it will go. Tighten the bolt. Remove the belt from the camshaft pulley.
    2.  

  10.  
  11. Remove the camshaft timing pulley as follows:
    1. Using Toyota tools Nos. 09249-63010 and 09960-10010, remove the bolt and the camshaft pulley.
    2.  

  12.  
  13. Remove the crankshaft pulley as follows:
    1. Use Toyota tools Nos. 09213-54015 and 09330-00021 to hold the crankshaft pulley. Remove the pulley set bolt and remove the pulley using a puller.
    2.  

  14.  
  15. Remove the No. 1 timing belt cover.
  16.  
  17. Remove the timing belt and the belt guide. If reusing the belt mark the belt and the crankshaft pulley in the direction of engine rotation and matchmark for correct installation.
