Timing Belt, Sprockets & Front Cover

Removal & Installation

Timing belt

To Remove:

  1. Disconnect the negative battery cable.
  2. Remove the exhaust side spark plugs, outer timing belt cover, and crankshaft pulley.
  3. Turn the crankshaft until the number one piston is at top dead center (TDC).

    CAUTION
    The camshaft belt tensioner tool (303-097) can be damaged when trying to relieve belt tension if you attempt to remove the belt without first loosening both the timing belt tensioner adjusting bolt and the spring pivot bolt.

  4. Loosen the timing belt spring pivot bolt, but do not remove it at this point in the procedure.
  5. Loosen the adjusting bolt slowly and release the spring tension.
  6. Turn the tensioner with the camshaft belt tensioner tool (303-097), against the spring pressure, clockwise to the farthest position.
  7. While holding it in this position, tighten the adjusting bolt to hold the tensioner away from the belt.
  8. Remove the timing belt.

To Install:

  1. Be certain that on piston number one, the crankshaft is at TDC with the crankshaft keyway pointing straight up and the circle on the crankshaft sprocket lined up with the notch on the engine front cover.
  2. Line up the timing marks.
  3. Install the timing belt over the crankshaft sprocket going counterclockwise over the oil pump sprocket and over the camshaft sprocket.
  4. Loosen the bolt allowing the tensioner pulley to press against the timing belt.

    NOTE: The timing belt tensioner should not be tightened or the belt tension will not be evenly distributed over the whole belt.

  5. Turn the crankshaft two revolutions clockwise. Next, slowly bring the crank to the number one position firing position with the keyway on the crank facing up. The dot on the crankshaft gear is lined up with the notch on the front cover.
  6. Check the timing mark alignment again. If necessary, repeat the procedure.
  7. Tighten the bolts. Torque the pivot bolt to 30-40 ft-lb (40-55 Nm). Torque the adjustment/locking bolt to 26-33 ft-lb (35-45 Nm).
  8. Install the crankshaft pulley and tighten the bolt. Torque to 93-121 ft-lb (125-165 Nm).
  9. Install the outer timing belt cover and tighten the bolt. Torque to 70-106 in-lb (8-12 Nm).
  10. Install the exhaust side spark plugs.
Sprockets

To Remove:

  1. Remove the timing belt.
  2. Install the camshaft sprocket holding/removing tool (303-098) onto the sprocket.
  3. Remove the camshaft sprocket.

To Install:

  1. Place the key and camshaft sprocket on the shaft.
  2. Install the camshaft sprocket holding/removing tool (303-098) onto the camshaft sprocket and tighten the bolt. Torque to 52-70 ft-lb (70-95 Nm).
  3. Remove the tool then install the timing belt.
Outer Cover

To Remove:

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Disconnect the negative battery cable.
  3. Remove the fan shroud.
  4. Loosen the bolts on the water pump pulley, but do not remove them at this point in the procedure.
  5. Remove the drive belt, the water pump pulley, and the fan and clutch assembly.
  6. Recover the refrigerant from the A/C system.
  7. Disconnect the A/C wiring connector.
  8. Remove the A/C compressor from the mounting bracket then remove the A/C mounting bracket with the power steering pump still attached.
  9. Remove the outer timing belt cover.

To Install:

  1. Install the outer timing belt cover. Torque to 70-106 in-lb (8-12 Nm).
  2. Install the A/C mounting bracket with the power steering pump still attached. Torque the M10 bolts and stud to 35 ft-lb (48 Nm) and torque the M8 bolt to 18 ft-lb (25 Nm).
  3. Install the A/C compressor to the mounting bracket. Torque to 16-20 ft-lb (21-28 Nm).
  4. Connect the A/C wiring connector.
  5. Refill the refrigerant into the A/C system.
  6. Install the fan and clutch assembly, the water pump pulley, and the drive belt.
  7. Tighten the bolts on the water pump pulley. Torque to 13-17 ft-lb (17-23 Nm).
  8. Install the fan shroud. Torque to 54-70 in-lb (6-8 Nm).
  9. Connect the negative battery cable.
  10. Start the engine. Check for leaks and repair as necessary.
Inner Cover

To Remove:

  1. Loosen oil pump sprocket bolt.
  2. Remove timing belt, timing belt tensioner, oil pump sprocket, and crankshaft pulley.
  3. Remove inner timing belt cover.

To Install:

  1. Install inner timing belt cover.
  2. Install crankshaft pulley. Torque to 93-121 ft-lb (125-165 Nm).
  3. Install the oil pump sprocket.
  4. Install the timing belt tensioner. Torque the pivot bolt to 30-40 ft-lb (40-55 Nm). Torque the adjustment/locking bolt to 26-33 ft-lb (35-45 Nm).
  5. Install the timing belt.
  6. Tighten the oil pump sprocket bolt. Torque to 30-40 ft-lb (40-55 Nm).
  7. Torque the camshaft bolt to 52-70 ft-lb (70-95 Nm).
