When should the timing belt be changed


I want to say it is every 100,000 miles. At the same time you do the timing belt replace the water pump and belt tensioner as well. They may not seem bad but go ahead and do it while being in there. It will save you problems down the road

18. NOTE: The directional arrow is necessary to ensure that the timing chain/belt (6268) can be reinstalled in the same direction.

If the timing chain/belt is to be reused, mark the direction of rotation on the timing chain/belt.

19. Loosen the timing chain/belt tensioner nut.

  1. Remove the timing chain/belt.
Installation
NOTE: Ensure that the timing marks on the camshaft sprockets (6256) and the seal plate are properly aligned. Ensure that the timing marks on the crankshaft sprocket and the oil pump housing are still aligned.



stv~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Pay special attention to the tooth shape of the timing belt. The current timing belts are not interchangeable with the timing belts from the 1993 model year. The 1993 model year uses a square or trapezoidal tooth timing belt while the current model year uses a rounded tooth design. The design change was made to extend the service life of the timing belt from 60,000 miles for the square or trapezoidal toothed belt to 105,000 miles for the rounded tooth belt. If the proper timing belt is not used, the customer may complain of a "whining" noise coming from the engine compartment. If the camshaft sprocket has a square cut in the valley of the gear tooth, it will require a square or trapezoidal tooth timing belt. If the camshaft sprocket has a rounded cut in the valley of the gear tooth, it will require a rounded tooth timing belt.
NOTE: If a new timing chain/belt is to be installed, make sure that the arrow is pointing away from the engine. If a timing chain/belt is to be reused, make sure that the directional arrow that was marked during disassembly is facing the correct direction.

NOTE: A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts and the crankshaft. These marks will help ensure that the engine (6007) is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the sprocket. Because the white timing marks are not evenly spaced you will need to refer to the following illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket.

NOTE: Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump (6600).

Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprockets following a counterclockwise path. Do not allow any slack in the timing chain/belt between the timing sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner.

  1. While holding the timing chain/belt tensioner with an Allen wrench, loosen the timing chain/belt tensioner nut.
  1. Allow the timing chain/belt tensioner to put pressure on the timing chain/belt.
  1. Use an Allen wrench to turn the timing chain/belt tensioner 70-80 degrees clockwise and tighten the timing chain/belt tensioner nut to 43-58 Nm (32-43 lb-ft).

    1. Rotate the crankshaft (6303) clockwise twice and align the No. 1 piston to Top Dead Center (TDC) on its compression stroke.
    1. Apply 98N (22 lbs) of force on the timing chain/belt between the rear camshaft sprocket and the timing chain/belt tensioner.
    2. NOTE: An assistant may be needed to adjust the timing chain/belt.

      While holding the timing chain/belt tensioner steady with an Allen wrench, loosen the timing chain/belt tensioner nut. Remove the Allen wrench and adjust the timing chain/belt tensioner as follows:
      1. Install a 0.35mm (0.0138 inch) thick and 12.7mm (0.500 inch) wide feeler gauge as shown.

  1. Turn the crankshaft clockwise to position the feeler gauge between the timing chain/belt tensioner and the timing chain/belt

  1. Tighten the timing chain/belt tensioner nut to 43-58 Nm (32-43 lb-ft).
  1. Turn the crankshaft clockwise to remove the feeler gauge from between the timing chain/belt tensioner and the timing chain/belt.
  1. Rotate the crankshaft clockwise twice and align the No. 1 piston to TDC on its compression stroke.
  1. Apply 98N (22 lbs) of force on the timing chain/belt between the rear and front camshaft sprocket.
    1. Measure the timing chain/belt deflection. Timing chain/belt deflection should be between 13-15mm (0.51-0.59 inch). If timing chain/belt deflection is not within specification, repeat steps 3-11. If the timing chain/belt cannot be adjusted to within specification, the timing chain/belt will have to be replaced.
    1. Position the lower engine front cover and install the five lower engine front cover bolts. Tighten the five lower engine front cover bolts to 3-5 Nm (27-44 lb-in).
    1. Install the outer timing chain/belt guide and the crankshaft pulley. Refer to the procedure in this section.
    1. Position the water pump pulley on the water pump and install the four water pump pulley bolts
    1. Use Strap Wrench D85L-6000-A or equivalent to hold the water pump pulley, and tighten the four water pump pulley bolts to 16-21 Nm (12-15 lb-ft).
    1. Position the RH outer engine and transmission splash shield and install the four RH outer engine and transmission splash shield bolts and two screws.
    1. Install the RH front wheel and tire assembly. Tighten the lug nuts (1012) to 98-118 Nm (72-87 lb-ft).
