First you need drain coolant. remove serp.belt. remove the fan clutch there is a tool for this but a craftsman strap wrench will hold the pulley just as well u need a 27mm. wrench for the nut and rad. shroud. next remove 4 bolts that hold a/c comp. to top of intake area. there is a wire to unhook lay a/c side. disconnect batt. and remove alternator 2 bolts lay to side and then remove aluminum bracket. now you have access to by pass hose and clear view of water pump.change bypass hose now you will thank me later then just remove the bolts holding pump fast and remove metal tube in pump and remove pump clean off old gasket. put new gasket on new pump with high tack sealer or other sealer install pump. replace o-ring on metal tube and put some silicone sealer on it as well. reinstall bracket alt. a/c comp. and wires that were un plugged. good luck

More Information:

There is no need to fool with the compresser or the alternator when replacing the water pump on a 318 (5.2L) Dodge Ram. I've replaced the water pump on my 1998 model twice, and never had to deal with other components that aren't directly tied to the water pump.

  1. Disconnect the negative battery cable

  4. Remove the cooling fan and fan shroud assembly.On gasoline engines remove water pump pulley
  5. Detach the coolant hoses from the water pump on gasoline engines.The coolant return hose is attached to a tube in the water pump.The tube is o-ring sealed and is held in by a tab and bolt remove the bolt and pull the tube from the pump
  6. Remove the water pump mounting bolts and detach the pump.It may be necessary to tap the pump with a softface hammer to break the gasket seal
