Print

Specific to:

  8.  
  9. Using the proper gauge feeler gauge, adjust the valves on cylinder number one.
  10.  
  11. Rotate the crankshaft 180 degrees. Using the proper gauge feeler gauge, adjust the valves on cylinder number three.
  12.  
  13. Rotate the crankshaft 180 degrees. Using the proper gauge feeler gauge, adjust the valves on cylinder number four.
  14.

Specific to:

Honda Fit 2007-2008


NOTE
Valves should be adjusted only when the cylinder head temperature is less than 100°F (38°C).

  1. Remove the cylinder head cover.
  2.  
  3. Set the No. 1 piston at top dead center (TDC). The ''UP'' mark on the camshaft sprocket should be at the top, and the TDC grooves on the camshaft sprocket should line up with the top edge of the head.
  4.  
  5. Select the correct thickness feeler gauge for the valves to check.
  6.  
  7. Proper valve clearance should be:

    Intake: 0.006-0.007 in. (0.15-0.19 mm)
     
    Exhaust: 0.010-0.012 in. (0.26-0.30 mm)

  8.  
  9. Insert the feeler gauge between the adjusting screw and the end of the valve stem and slide it back and forth; a slight amount of drag should be felt.
  10.  
  11. If too much or too little drag is present, loosen the locknut, and turn the adjusting screw until the drag on the feeler gauge is correct.
  12.  
  13. Tighten the locknut to 10 ft. lbs. (14 Nm) and recheck the clearance. Repeat the adjustment if necessary.
  14.  
  15. Rotate the crankshaft clockwise. Align the No. 3 piston TDC groove on the camshaft sprocket with the top edge of the head.
  16.  
  17. Check and if necessary, adjust the valve clearance on No. 3 cylinder.
