Removal & Installation

Print

2.4L Engine



This engine uses a die-cast aluminum body water pump with a stamped steel impeller. The water pump bolts directly to the block. Cylinder block-to-water pump sealing is provided by a large rubber O-ring. The water pump is driven by the timing belt that must be removed to service the water pump.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect the negative battery cable from the left shock tower.
    NOTE
    The ground cable is equipped with an insulator grommet which should be placed on the stud to prevent the negative battery cable from accidentally grounding.


    NOTE
    This procedure requires removing the engine timing belt and the auto-tensioner. The factory specifies that the timing marks should always be aligned before removing the timing belt. Set the engine at Top Dead Center (TDC) on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

  4.  
  5. Drain the cooling system.
  6.  
  7. Remove or disconnect the following:
    NOTE
    Do not disconnect the power steering fluid lines.


    WARNING
    With the timing belt removed, DO NOT rotate the camshaft or crankshaft or damage to the engine could occur.


    NOTE
    Do not allow the camshafts to turn when the camshaft sprockets are being removed.

  8.  

To install:

  1. Thoroughly clean all sealing surfaces. Replace the water pump if there are any cracks, signs of coolant leakage from the shaft seal, loose or rough turning bearings, damaged impeller or sprocket or sprocket flange loose or damaged.
  2.  
  3. Install a NEW rubber O-ring into the water pump.
    NOTE
    Be sure the O-ring is properly seated in the water pump groove before tightening the screws. An improperly located O-ring may cause damage to the O-ring and cause a coolant leak.

  4.  
  5. Install the water pump. Torque the bolts to 105 inch lbs. (12 Nm).
  6.  
  7. Pressurize the cooling system to 15 psi (103.4 kPa) and check for leaks. If no leaks are found, release the pressure and continue the engine assembly process.
  8.  
  9. Install or connect the following:
    NOTE
    DO NOT allow the camshafts to turn while the sprocket bolts are being tightened to maintain timing mark alignment.


    WARNING
    Do not attempt to compress the tensioner plunger with the tensioner assembly installed in the engine. This will cause damage to the tensioner and other related components. The tensioner MUST be compressed in a vise.
