  1. Temporarily install the crankshaft pulley bolt and the washer to the crankshaft.

NOTICE: Do not install the tensioner as it removed.

e. Remove the timing belt in this order.

21. INSPECT TIMING BELT

NOTICE:

^ Do not bend, twist or turn the timing belt inside out. ^ Do not allow the timing belt to come into contact with oil, water or steam. ^ Do not utilize timing belt tension when installing or removing the mounting bolt of the camshaft timing pulley.

Check the belt for any defects as shown in the illustrations. Also, check these points. a. If there is premature parting, ^ Check for proper installation. ^ Check the timing cover gasket for damage and proper installation. b. If the belt teeth are cracked or damaged, check to see if either camshaft is locked. c. If there is noticeable wear or cracks on the belt face, check to see if there are nicks on the side of the idler pulley lock and water pump. d. If there is wear or damage on only one side of the belt, check the belt guide and the alignment of each pulley. e. If there is noticeable wear on the belt teeth, ^ Check timing cover for damage. ^ Check gasket has been installed correctly. ^ Check for foreign object on the pulley teeth. If there is any doubt about the belt condition, replace the timing belt.

  1. INSTALL TIMING BELT

a. Remove any oil or water on the pulleys, and keep them clean.

NOTICE:

^ If there is a trace of water and/or oil on the timing belt, repair the leakage and install a new timing belt. ^ Wipe only the pulleys; do not use any cleaning agent.

b. Inspect the idler pulleys.

  1. Check that the idler pulley turns smoothly.
  2. Visually check the seal portion of the idler pulley for oil leakage. c. Inspect the water pump.
  3. Turn the pulley, and check that water pump bearing moves smoothly and does not make noise.
  4. Visually check the drain hole for coolant leakage. d. Temporarily install the crankshaft pulley bolt and the washer to the crankshaft.

e. Turn the crankshaft counterclockwise by approximately 60°.

NOTICE: To prevent contacting the piston head and the valve head, set the crankshaft pulley at 60° BTDC/compression position.

f. Using SST, turn the camshaft pulley, and align the timing marks of the timing pulley and the No. 3 timing belt cover. SST 09960 - 10010 (09962-01000, 09963-01000)

g. Turn the crankshaft, and align the timing marks of the crankshaft timing pulley and the oil pump body.

h. Face the front mark on the timing belt forward.

NOTICE: Always turn the crankshaft clockwise.

h. Check the timing marks of the RH and LH timing pulleys are aligned with the timing marks of the No. 3 timing belt cover as shown in the illustration. If the marks do not align, remove the timing belt and reinstall it. i. Remove the crankshaft pulley bolt.
