When replacing the water pump on a car equipped with the V-6 engine, the timing cover must be clamped to the cylinder block PRIOR TO removing the water pump bolts. Certain bolts holding the water pump pass through the front cover and when removed, may allow the front cover to pull away from the cylinder block, breaking the seal. This may or may not be readily apparent and if left undetected, could allow coolant to enter the crankcase. To prevent this possible separation during water pump removal, Special Tool #J29176 will have to be installed.

  1. Disconnect the negative battery cable. Drain the cooling system.
  2.  
  3. Remove the drive belts for the water pump and accessories.
  4.  
  5. Disconnect the coolant hoses from the water pump.
  6.  
  7. Install the Special Tool #J29176 as shown in the illustration (V-6 engines only).
  8.  
  9. Remove the water pump mounting bolts and then remove the pump.
  10.  

To install:

  1. No gasket is used. Clean the mating surfaces thoroughly, then apply a 3 / 32 " bead of RTV sealant to the water pump sealing surface.
  2.  
  3. While the sealer is still wet, install the pump onto the engine. Tighten the bolts to 25 ft. lbs. (30 Nm) on the four cylinder engine. On the V-6, tighten the small bolts to 8 ft. lbs. (10 Nm), the medium bolts to 16 ft. lbs. (21 Nm) and the large bolts to 25 ft. lbs. (30 Nm).
  4.  
  5. Remove the Special Tool from the V-6 engines.
  6.  
  7. The remainder of installation is the reverse of removal. Adjust the drive belt tension after installation. Add the proper amount of coolant to bring the cooling system to the proper level.
