  1. Drain the cooling system.

  2. Remove the bolts securing the fan shroud to the radiator, if so equipped and position the shroud over the fan.

  3. Disconnect the lower radiator hose, heater hose and by-pass hose at the water pump. Remove the drive belt(s), fan, fan spacer and pulley. Remove the fan shroud, if so equipped.

  4. Loosen the alternator pivot bolt and the bolt attaching the alternator adjusting arm to the water pump. If applicable, remove the power steering pump bracket from the water pump and position it out of the way.
