Removal & Installation



4a-FE And 7A-FE
  1. Remove all necessary components for access to the timing belt covers.
    CAUTION
    If equipped with an air bag, be sure to disconnect the negative battery cable and wait at least 90 seconds before proceeding.

  2.  
  3. Turn the crankshaft to align the timing mark on crankshaft pulley at 0 , setting the piston in No. 1 cylinder at Top Dead Center (TDC) on the compression stroke. Check that the valve lifters on the No. 1 cylinder are loose. If not, turn crankshaft pulley 1 complete revolution (360 degrees).
  4.  
  5. Remove the nine bolts and timing belt covers from the engine.
  6.  
  7. Slide the timing belt guide from crankshaft.
  8.  
  9. Set the camshaft and crankshaft timing sprockets to align the marks.
    WARNING
    Do not turn crankshaft or camshaft independently after removal of timing belt. Binding or damage to engine components could result. If the timing belt is to be reused, mark timing belt with arrow showing direction of engine revolution. Place matchmarks where timing belt meets with crankshaft timing sprocket and camshaft timing sprocket to ensure installation in the same position.

  10.  
  11. Remove the timing belt tensioner bolt, tensioner and the tension spring.
  12.  
  13. Remove the timing belt from camshaft and crankshaft timing sprockets.
  14.  
  15. Remove the timing belt.
    WARNING
    Do not bend, twist or turn the timing belt inside out. Do not allow the belt to come in contact with oil, coolant or steam.

NOTE
Inspect the camshaft timing sprocket to ensure mark is still aligned as indicated.

  1. Reinstall the timing belt tensioner and the tension spring. Pry the tensioner to the left as far as it will go and temporarily tighten the retaining bolt.
  2.  
  3. Install the timing belt. If reinstalling the old belt, observe the matchmarks made during removal. Be sure the belt is fully and squarely seated on the sprockets.
  4.  
  5. Loosen the retaining bolt for the timing belt tensioner and allow it to tension the belt.
  6.  
  7. Temporarily install the crankshaft pulley bolt and turn the crank clockwise 2 full revolutions from TDC to TDC. Insure that each timing mark realigns exactly.
  8.  
  9. Tighten the timing belt tensioner bolt to 27 ft. lbs. (37 Nm).
  10.  
  11. Measure the timing belt deflection at the SIDE point, looking for 1 / 4 in. (5-6mm) of deflection at 4.4 lbs. (2 kg) of pressure. If the deflection is not correct, adjust with the timing belt tensioner.
  12.  
  13. Install the timing belt guide, with the cup side facing outward, onto the crankshaft and install the timing belt covers from the lowest to the highest. Tighten the nine cover bolts to 62 inch lbs. (7 Nm).
  14.  
  15. Install all applicable remaining components. During assembly, be sure to tighten the crankshaft pulley bolt to 87 ft. lbs. (118 Nm), the mounting bracket-to-engine mount bolt to 47 ft. lbs. (64 Nm), the mounting bracket-to-engine mount nuts to 38 ft. lbs. (52 Nm), the engine mount-to-body bolt A to 19 ft. lbs. (25 Nm), the engine mount-to-body bolts B to 19 ft. lbs.
