    To install:

    1. Install the water pump using new O-rings to the engine block. Lubricate the inner O-ring with clean engine oil and the outer O-ring with engine coolant. Ensure the water pump sprocket and timing chain are engaged. Torque the 3 water pump mounting bolts evenly to 85 inch lbs. (10 Nm).
    2.  
    3. Rotate the crankshaft pulley clockwise so the timing chain on the tensioner side is loose.
    4.  
    5. Install the primary timing chain tensioner.
    6.  
    7. Apply a continuous 0.091-0.130 in. (2.3-3.3mm) bead of liquid sealant to the mating surfaces of the timing chain tensioner and water pump covers.
    8.  
    9. Install the timing chain tensioner and water pump covers to the engine block. Torque the bolts to 97 inch lbs. (11 Nm).
    10.  
    11. Install or connect the following:

      Water drain plug
       
      Cooling fan
       
      Radiator hoses
       
      Accessory drive belts
       
      Negative battery cable
       

    12.  
    13. Fill the cooling system.
    14.  
    15. Start the engine, check for leaks and repair if necessary.

    1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
    2.  
    3. Drain the cooling system.
    4.  
    5. Position a jack under the oil pan for support. Be sure to place a block of wood on the jack for protection to the engine parts.
    6.  
    7. Remove or disconnect the following:

      Negative battery cable
       
      Right side engine mount and bracket
       
      Drive belts and the idler pulley bracket
       
      Chain tensioner cover and the water pump cover
       

    8.  
    9. Push the timing chain tensioner sleeve and apply a stopper pin so it does not return.
    10.  
    11. Remove or disconnect the following:

      Timing chain tensioner assembly
       
      3 bolts that secure the water pump
       

    12.  
    13. Rotate the crankshaft 20 degrees counterclockwise to provide timing chain slack.
    14.  
    15. Put M8 bolts in 2 M8 threaded holes of the water pump.
    16.  
    17. Tighten each bolt by turning alternately 1 / 2 turn until they reach the timing chain rear case. Be sure to turn each bolt 1 / 2 turn at a time to prevent damage.
    18.  
    19. Lift up the water pump and remove it.
    20.  
    21. When removing the water pump, do not allow the water pump gear to hit the timing chain.
    22.  
    23. Remove and discard the O-rings from the water pump.
    24.  
    25. Clean all traces of liquid gasket from the water pump and covers.
    26.  

    To install:

    1. Install or connect the following:

      Water pump using new O-rings to the engine block. Torque the 3 water pump mounting bolts evenly to 62-89 inch lbs. (7-10 Nm)
       

    2.  
    3. Rotate the crankshaft pulley to its original position by turning it 20 degrees clockwise.
    4.  
    5. Install or connect the following:

      Timing chain tensioner and torque the bolts to 75-89 inch lbs. (9-10 Nm)
       

    6.  
    7. Remove the stopper pin from the timing chain tensioner.
    8.  
    9. Apply a continuous 0.091-0.130 in. (2.3-3.3mm) bead of liquid sealant to the mating surfaces of the timing chain tensioner and water pump covers.

      Timing chain tensioner and water pump covers to the engine block. Torque the bolts to 89-108 inch lbs. (10-13 Nm)
       
      Drive belts and the idler pulley bracket
       
      Right side engine mounting bracket and the engine mount
       
      Negative battery cable
       

    10.  
    11. Remove the jack from under the engine and install the drain plugs to the cylinder block.
    12.  
    13. Fill the cooling system.
    14.  
    15. Start the engine, check for leaks and repair if necessary.
