Hi,

1. Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover. To remove the timing belt, first rotate the engine and align the timing marks to TDC

NOTE: Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.

CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. To install:
  2. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
  3. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt. NOTE: The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.

  4. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
  5. Install the crankshaft pulley and belt guide.
  6. Install the timing belt cover.
  7. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
  8. Position the alternator and drive belts, then adjust and tighten it to specifications.
  9. Start the engine and check the ignition timing. Adjust the timing, if necessary.
Let me know,if needed further assistance.

Hope i helped you.

Where is the ignition module control located on 1996 ranger 2.3 e


It does not have an ignition control module. The PCM (powertrain control module) fires the coil pack based on signal it recieves from the crankshaft position sensor and the camshaft position sensor.
