  1. drain coolant from radiator and block
  2. remove the air cleaner
  3. loosen and remove the power steering belt
  4. disconnect the upper water hose from the radiator and thermostat housing
  5. remove the fan and coupling
  6. remove the bottom water hose from the water pump
  7. remove the hose from the intake connection from the water pump
  8. set the engine at TDC.Matchmark the distributor and engine and remove the distributor.Crank the engine with a socket wrench on the crankshaft pulley bolt.Crank in the normal direction of rotation only.
  9. turn the balancer so that the recesses provide access to the mounting bolts.Rotate the engine in the normal direction of rotation only.
  10. remove the water pump
  11. clean the mounting surfaces of the water pump and block.
  12. installation is the reverse of removal.Always use a new gasket.Set the engine to TDC and install the distributor so that the distributor rotor points to the notch on the distributor housing.Fill the cooling system and check ignition timing.
