REMOVAL & INSTALLATION



All Engines

See Figures 1 through 7

  1. Place a clean drain pan under the radiator. Remove the drain plug from the front side of the engine block and the drain the cooling system to a level below the water pump.
  2.  


CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. If the water pump and alternator operate from the same drive belt, loosen the alternator bolts, move the alternator toward the cylinder block and remove the drive belt.
