  1. Disconnect the negative battery cable. Remove the engine under cover.
  2.  
  3. Raise and safely support the weight of the engine using the appropriate equipment. Remove the front engine mount bracket and accessory drive belts.
  4.  
  5. Remove the coolant reservoir tank.
  6.  
  7. Remove timing belt upper and lower covers.
  8.  
  9. Make a mark on the back of the timing belt indicating the direction of rotation so it may be reassembled in the same direction if it is to be reused. Loosen the timing belt tensioner and remove the timing belt.
  10.  

NOTE:If coolant or engine oil comes in contact with the timing belt, they will drastically shorten its life. Also, do not allow engine oil or coolant to contact the timing belt sprockets or tensioner assembly.

  1. Remove the tensioner spacer, tensioner spring and tensioner assembly.
  2.  
  3. Inspect the timing belt for cracks on back surface, sides, bottom and check for separated canvas. Check the tensioner pulley for smooth rotation.
  4.  

To install:
  1. Position the tensioner, tensioner spring and tensioner spacer on engine block.
  2.  
  3. Align the timing marks on the camshaft sprocket and crankshaft sprocket. This will position No. 1 piston on TDC on the compression stroke.
  4.  
  5. Position the timing belt on the crankshaft sprocket and keeping the tension side of the belt tight, set it on the camshaft sprocket.
  6.  
  7. Apply counterclockwise force to the camshaft sprocket to give tension to the belt and make sure all timing marks are aligned.
  8.  
  9. Loosen the pivot side tensioner bolt and the slot side bolt. Allow the spring to take up the slack.
  10.  
  11. Tighten the slot side tensioner bolt and then the pivot side bolt. If the pivot side bolt is tightened first, the tensioner could turn with bolt, causing over tension.
  12.  
  13. Turn the crankshaft clockwise. Loosen the pivot side tensioner bolt and then the slot side bolt to allow the spring to take up any remaining slack. Tighten the adjuster bolt to 18 ft. lbs. (24 Nm).
  14.  
  15. Check the belt tension by holding the tensioner and timing belt together by hand and give the belt a slight thumb pressure at a point level with tensioner center. Make sure the belt cog crest comes as deep as about 1 / 4 of the width of the slot side tensioner bolt head. Do not manually overtighten the belt or it will howl.
  16.  
  17. Install the timing belt covers and all related items.
  18.  
  19. Connect the negative battery cable.

  10.  
  11. Remove the camshaft sprocket bolt and pull the sprocket from the camshaft.
  12.  
  13. Remove the crankshaft sprocket bolt and pull the crankshaft sprocket and flange from the crankshaft.
  14.  
  15. Remove the plug on the left side of the block and insert an 8mm diameter metal bar in the opening to keep the silent shaft in position.
  16.  
  17. Remove the oil pump sprocket retaining nut and remove the oil pump sprocket.
  18.  
  19. Loosen the right silent shaft sprocket mounting bolt until it can be turned by hand.
  20.  
  21. Remove the belt tensioner and remove the timing belt.
  22.  

Do not attempt to turn the silent shaft sprocket or loosen its bolt while the belt is off.

  1. Remove the silent shaft belt sprocket from the crankshaft.
  2.  
  3. Check the belt for wear, damage or glossing. Replace it if any cracks, damage, brittleness or excessive wear are found.
  4.  
  5. Check the tensioners for a smooth rate of movement.
  6.  
  7. Replace any tensioner that shows grease leakage through the seal.
  8.  

To install:
  1. Install the silent shaft belt sprocket on the crankshaft, with the flat face toward the engine.
  2.  
  3. Apply light engine oil on the outer face of the spacer and install the spacer on the right silent shaft. The side with the rounded shoulder faces the engine.
  4.  
  5. Install the sprocket on the right silent shaft and install the bolt but do not tighten completely at this time.
  6.  

Align the silent shaft and oil pump sprockets using the timing marks. If the 8mm metal bar can not be inserted into the hole 2.36 in. (60mm), the oil pump sprocket will have to be turned 1 full rotation until the bar can be inserted to the full length. If this procedure is not followed, the engine will run but vibrate at high engine rpm.

  1. Install the silent shaft belt and adjust the tension, by moving the tensioner into contact with the belt, tight enough to remove all slack. Tighten the tensioner bolt to 21 ft. lbs. (28 Nm).
  2.  
  3. Tighten the silent shaft sprocket bolt to 28 ft. lbs. (38 Nm).
  4.  
  5. Install the flange and crankshaft sprocket on the crankshaft. The flange conforms to the front of the silent shaft sprocket and the timing belt sprocket is installed with the flat face toward the engine.

SILENT SHAFT BELT REPLACEMENT



2.0L and 2.4L Engines

When replacing the timing belt, the manufacturer recommends to replace the silent shaft belt.

  1. After removing the timing belt, mark arrows on the belt to indicate direction of rotation (clockwise).
  2.  

If the silent shaft belt is not installed properly, the engine will run but with a vibration. Align the silent shaft and oil pump sprockets using the timing marks. If the 8mm metal bar can not be inserted into the hole 2.36 inch (60mm), the oil pump sprocket will have to turned 1 full rotation until the bar can be inserted to the full length.

  1. Align the timing marks before removal. Loosen the belt tensioner and remove the belt.
  2.  

To install:
  1. Make sure the crankshaft and silent shaft sprocket timing marks are aligned.
  2.  
  3. Fit the belt over the sprockets. Make sure there is no slack in the belt.
  4.  
  5. Temporarily fix the timing belt tensioner so that the center of the tensioner pulley is to the left and above the center of the installation bolt. Temporarily attach the tensioner pulley so that the flange is toward the front of the engine.
  6.  
  7. Adjust the belt so that the slack between the 2 sprockets is within 0.20-0.28 inch (5-7mm).
