ADJUSTMENT CRV Models



The radio may contain a coded anti-theft circuit. Obtain the security code before disconnecting the battery.

  1. Disconnect the negative battery cable.
  2.  
  3. The valves should be checked and adjusted when the engine is cold. If the engine has been run, allow it to cool to below 100°F (38°C) before beginning adjustments.
  4.  
  5. The valves must be checked or adjusted for each cylinder with the cylinder in the TDC position of the compression stroke.
  6.  
  7. Remove the cylinder head cover and the upper timing belt cover.
  8.  
  9. Rotate the crankshaft in a counterclockwise direction and align the painted white notch Top Dead Center (TDC) mark on the crankshaft pulley with the pointer on the engine cover for the No. 1 cylinder compression stroke. The UP marks on the camshaft sprockets should be facing up and TDC marks of the camshaft sprockets should align with the pointers on the valve cover gasket surface of the cylinder head.
  10.  
  11. With the cylinder at TDC on the compression stroke, check the valve clearance by inserting the correct size feeler gauge between the rocker arm and the camshaft lobe of the valves for that cylinder.
  12.  
  13. To check the intake valves proceed as follows:
    1. Using a 0.003 in. (0.08mm) feeler gauge, see if the gauge will slide between the camshaft lobe and the rocker.
    2.  
    3. If the 0.003 in. (0.08mm) feeler gauge does not fit between the rocker and the camshaft lobe, then adjust the valve. If the feeler gauge did fit, then try inserting a 0.006 in. (0.15mm) feeler gauge.
    4.  
    5. If the 0.006 in. (0.15mm) feeler gauge can be inserted between the rocker and the camshaft lobe, then adjust the valve. If the feeler gauge cannot be inserted, then the valve adjustment for that valve is within the range specified.

  1. The valve adjustment specification for the CRV intake valve is 0.003-0.005 in. (0.08-0.12mm). To adjust an intake valve, proceed as follows:
    1. Loosen the locknut and turn the adjusting screw counterclockwise to loosen the adjustment.
    2.  
    3. Insert a 0.004 in. (0.10mm) feeler gauge between the camshaft lobe and the rocker.
    4.  
    5. Hold the locknut and turn the adjusting screw until a very light resistance is felt. The feeler gauge should be able to be moved with a slight amount of drag.
    6.  
    7. While holding the adjustment screw in place, tighten the locknut and then recheck the clearance.
    8.  

  2.  
  3. To check the exhaust valve clearance proceed as follows:
    1. Using a 0.006 in. (0.15mm) feeler gauge, see if the gauge will slide between the camshaft lobe and the rocker.
    2.  
    3. If the 0.006 in. (0.15mm) feeler gauge does not fit between the rocker and the camshaft lobe, then adjust the valve. If the feeler gauge did fit, then try inserting a 0.009 in. (0.22mm) feeler gauge.
    4.  
    5. If the 0.009 in. (0.22mm) feeler gauge can be inserted between the rocker and the camshaft lobe, then adjust the valve. If the feeler gauge cannot be inserted, then the valve adjustment for that valve is within the range specified.
    6.  

  4.  
  5. The valve adjustment specification for the CRV exhaust valve is 0.006-0.008 in. (0.16-0.20mm) To adjust an exhaust valve, proceed as follows:
    1. Loosen the locknut and turn the adjusting screw counterclockwise to loosen the adjustment.
    2.  
    3. Insert a 0.007 in. (0.18mm) feeler gauge between the valve tip and the rocker.
    4.  
    5. Hold the locknut and turn the adjusting screw until a very light resistance is felt. The feeler gauge should be able to be moved with a slight amount of drag.
    6.  
    7. While holding the adjustment screw in place, tighten the locknut and then recheck the clearance.
    8.  

  6.  
  7. Repeat the checking procedure for each valve and adjust the clearance for any valve found to be out of adjustment.
  8.  
  9. Once all of the valves for a cylinder have been checked, the crankshaft must be rotated counterclockwise to check the valves of another cylinder.
  10.  
  11. When rotating the crankshaft counterclockwise, the adjustment order is cylinder No. 1, cylinder No. 3, cylinder No. 4, cylinder No. 2.
  12.  
  13. Rotate the crankshaft counterclockwise 180° to bring the next cylinder to the TDC/compression position.
  14.  
  15. Refer to the following information to verify the cylinder to be checked is in the TDC/compression position:

    At TDC/compression for the No. 1 cylinder, the camshaft sprocket UP marks are pointed straight up, and the TDC marks align with the edge of the cylinder head.
     
    At TDC/compression for the No. 3 cylinder, the camshaft sprocket UP marks are both horizontal, pointed to the left.
     
    At TDC/compression for the No. 4 cylinder, the camshaft sprocket UP marks are pointed straight down, and the TDC marks align with the edge of the cylinder head.
     
    At TDC/compression for the No. 2 cylinder, the camshaft sprocket UP marks are both horizontal, pointed to the right.
     

  16.  
  17. After checking all of the valves for all of the cylinders, check, and if necessary, retighten the crankshaft pulley bolt in a clockwise direction to 130 ft. lbs. (177 Nm).
  18.  
  19. Thoroughly clean the cylinder head cover gasket and make sure it is fully seated into the head cover. Apply a liquid gasket sealant to the corners of the half circle portions of the gasket.
  20.  
  21. Install the cylinder head and timing belt covers, tightening the fasteners evenly to 86 inch pounds (9.8 Nm).
  22.  
  23. Reconnect the negative battery cable. Enter the radio security code.
