Timing Belt Replacement
Notes

Removal Procedure

  1. Remove the front timing belt cover.

  1. Rotate the crankshaft using the J 42098 until the #1 cylinder is at 60 degrees before top dead center (BTDC).
  2. Install the J 42069 Crankshaft Locking Tool.

  1. Rotate the crankshaft in the engine rotational direction (clockwise) using the J 42098 until the #1 cylinder is at top dead center (TDC) and tighten the lever arm to the water pump pulley flange. Important: Ensure that the alignment of the crankshaft is not 180 degrees off. The alignment mark must align with the corresponding notches on the rear timing belt cover.
  2. Install the 1-2 and 3-4 camshaft locks, the J42069-1 Timing Belt Alignment Kit and the J42069-2. Important: Do not rotate the crankshaft if the camshafts are not locked in place with the 1-2 and 3-4 camshaft locks (J42069-1 and J42069-2). Do not rotate the camshafts unless the crankshaft is at 60 degrees BTDC or the valves may contact the crankshaft.
  3. Loosen the tensioner pulley.
  4. Remove the timing belt.

Installation Procedure

  1. Position crank at 60 degrees before TDC. Notice: Refer to Fastener Notice in Cautions and Notices.

  1. Install the lower idler pulley. Tighten the lower idler pulley bolt to 40 Nm (30 ft. lbs.)

  1. Install the upper idler pulley and hand tighten bolt.



Important: With the camshaft locks installed, verify the distance between the camshaft sprockets with the Green Test Belt located in the Timing Belt Alignment Kit J 42069.

  1. Install the timing belt tensioner and hand tighten nut and washer.
  2. Start #1 and #2 camshaft sprockets, route belt around #1 and #2 sprockets while aligning belt marks to marks on the sprocket and rear cover.
  3. Install the belt around the timing belt tensioner.
  4. Route belt around upper idler pulley.
  5. Route belt around #3 and #4 camshaft sprockets while aligning belt marks to marks on sprockets and rear cover.
  6. Route belt around crankshaft hub sprockets while aligning marks on belt to marks on the crankshaft hub sprocket.

  1. Install the wedge tool J 42069-30 to lock the timing belt onto crankshaft hub sprocket.

  1. With belt firmly engaged on crankshaft hub, carefully rotate the crankshaft counterclockwise to get belt slack on lower idler pulley side.
  2. Route belt around the lower idler pulley.

  1. Remove the wedge tool J 42069-30.

  1. Re-install the crankshaft locking tool J 42069-10 and tighten the lever arm to the water pump pulley flange.
  2. Perform the following in sequence:
    1. Install the camshaft checking gage to cams 3 and 4 and verify alignment marks are within 2 mm of each other.
    2. Install 3 and 4 camshaft locks if properly aligned.
    3. Install camshaft checking gage to cams 1 and 2.

    1. Rotate #1 camshaft sprocket counterclockwise to remove slack between 1 and 2, and 3 and 4 cams.

Important: Ensure that the camshaft timing marks are to the left (retard) side of the checking gage.

    1. Rotate the upper idler pulley counterclockwise until the marks are properly aligned within 2 mm of each other.
    2. Install 1 and 2 camshaft locks when properly aligned. Tighten the idler pulley bolt to 40 Nm (30 ft. lbs.)

  1. Adjust the timing belt tensioner that the center alignment mark is approximately 3mm (1/8 inch) above the alignment on the spring loaded idler.

  1. Remove the 1 and 2 and 3 and 4 camshaft locks.
  2. Remove the timing belt kit J 42069-1 and J 42069-2.
  3. Remove the crankshaft locking tool J 42069-10. Important: If the TDC is passed, do not rotate the crankshaft counterclockwise. This will not allow proper slack to be taken up between the timing belt tensioner and crankshaft sprocket. To correct, rotate the crankshaft two additional turns.
  4. Rotate the crankshaft 1 3/4 turns clockwise, install the crankshaft locking tool J 42069-10, and stop at TDC.

  1. Tighten lever arm to the water pump pulley flange.

  1. Install the checking gage J 42069-20 and verify the marks are 2 mm of each other.

  1. Adjust the timing belt tensioner that the center alignment mark is approximately 3 mm above the alignment mark on the spring loaded idler and tighten the timing belt tensioner nut. Tighten the timing belt tensioner nut to 20 Nm (15 ft. lbs.)
  2. Remove the crankshaft locking tool J 42069-10 and the checking gage J 42069-20.
  3. Install the front timing belt cover.
  4. Lower the vehicle.
  5. Install the air cleaner assembly.
  6. Connect the negative battery cable. Tighten the battery terminal bolt to 17 Nm (13 ft. lbs.)

Sorry but a picture of the belt tensioner is not answering my question. I need to locate the crankshaft mark to a mark on the engine casing when at tdc?
Expert:  David replied 5 years ago.
Hi thank you for your question hope this helps.

Here are pictures of the crankshaft and camshafts timing marks.

Do you see any notches in / on the cover behind the sprocket? Some times the marks can wear off in this case it is a little harder to set the timing marks. if this is the case let me know.

Rotate the crankshaft and align the Top Dead Center (TDC) mark (2) on the sprocket with the pointer on the oil pump housing (1)
graphic

Rotate the left camshaft sprocket to TDC by aligning the mark (2) on the sprocket with the pointer (1) on the cover
graphic

Rotate the right camshaft sprocket to TDC by aligning the mark (2) on the sprocket with the pointer (1) on the cover

Hope this helps
Good luck
