Fig. Fig. 2 Securing the timing chain tensioner with a piece of wire (1)

  1. Remove the engine/transaxle assembly from the vehicle according to the "Engine Removal and Installation" procedure in the beginning of this section.
  2.  
  3. Remove the timing cover and clean all of the gasket surfaces.
  4.  
  5. If the timing chain is to be replaced, secure the shoe of the tensioner (component that actually contacts the chain) to the body of the tensioner with a piece of wire.
  6.  
  7. Remove the chain tensioner assembly.
  8.  
  9. Remove the camshaft sprocket bolt and install a suitable puller. Tighten the puller to draw the camshaft sprocket and chain off of the camshaft.
  10.  
  11. If the crankshaft gear is to be replaced, draw the gear off of the crankshaft with a suitable puller.
  12.  
  13. Press the crankshaft sprocket onto the crankshaft using a suitable tool.
  14.  
  15. Temporarily install the camshaft sprocket (marking facing outward) without the timing chain and align the timing marks.
  16.  

Do not rotate either the camshaft or the crankshaft once the timing marks are aligned.

  1. Remove the camshaft sprocket.
  2.  
  3. Position the timing chain onto the camshaft sprocket and reinstall the camshaft sprocket/timing chain assembly, making sure that the timing marks are aligned properly.
  4.  
  5. Install the camshaft sprocket retaining bolt and tighten the bolt to 20 ft. lbs.
  6.  
  7. Install the timing chain tensioner.
  8.  
  9. Using a new gasket and cover-to-oil pan seal, install the timing cover.
  10.  
  11. Install the engine/transaxle assembly according to the "Engine Removal and Installation" procedure in the beginning of this section.
  12.

Fig. Fig. 3 Using a special tool to move the timing chain tensioner on the Alliance and Encore

  1. Disconnect the battery ground.
  2.  
  3. Drain the engine oil.
  4.  
  5. Remove the engine support rod and spacer.
  6.  
  7. Remove the oil pan.
  8.  
  9. Remove the air conditioning compressor belt.
  10.  
  11. Remove the water pump belt, pulley and hub.
  12.  
  13. On cars with air conditioning, place a jack under the engine cradle, remove the two bolts on the right side of the cradle and lower the jack until the pulley clears the crossmember.
  14.  
  15. Remove the timing chain cover. Crank the engine until the V shaped timing marks on the sprockets are aligned.
  16.  
  17. Move the chain tensioner as far as possible from the chain and secure it out of the way.
  18.  
  19. Remove the tensioner.
  20.  
  21. Remove the camshaft sprocket bolt, pull the sprocket loose with a three-jawed puller and remove the sprocket and chain.
  22.  
  23. To pull the crankshaft sprocket, you must machine a large depression into the head of a bolt that will fit into the nose of the crankshaft. Use this bolt as a center point for a puller.
  24.  
  25. Installation is the reverse of removal. Some later models have a timing cover assembled with RTV silicone gasket material in place of a paper gasket. Use only this material when assembling. The camshaft sprocket bolt is torqued to 22 ft. lb. Make sure that the timing marks are aligned.

  18.  
  19. Install the crankshaft key and rotate the crankshaft so that the key faces up.
  20.  
  21. Place the crankshaft sprocket inside the timing chain to simulate installation. Make sure that the timing marks align properly.
