Can i replace the water pump in a 1997 Nissan pickup without messing with (replacing) the timing chain?


D21 Pick up? The water pump is not timing belt driven. It is drive belt drive with a pulley held on with 4 bolts.

So, yes, the water pump can be replaced without touching the timing components. :-)

I believe the bearing on my waterpump is bad. while driving the fan began rubbing the shroud and eventually wedged against the waterpump pulley. before removing the radiator,shroud and hoses i checked...


You can't remove the fan and pump together. The pulley will be i nthe way. You must remove the fan and clutch, then the pulley then you will have access to the water pump bolts as well as the other components which must be removed to get the pump off.

  1. Drain the cooling system.
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by 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. Remove the bolts securing the fan shroud to the radiator, if so equipped and position the shroud over the fan.
  2. 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.
  3. 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.
t may be easier to remove the pulley from the water pump shaft by using belt tension to hold the pulley prior to removal.
  1. Remove the bolts securing the water pump to the timing chain cover and remove the water pump.
To install:
  1. Coat a new gasket with sealer and install the water pump. Tighten the bolts to 18 ft. lbs. (24 Nm).

Water pump instillation


Remove the Fan Shroud. You have to do this with Both the Old and New Waterpump out. The fan has 4 Nuts that hold it on to the Pulley. Remove these and Remove the Fan and the Pulley. You will need the Studs off of the Old Waterpump and they are Threaded into the Small Circle that is on the Front of the Waterpump Under the Pulley. There is no Easy way to get these off. It is Tough. Then when you are done Fighting with these, Install the Studs on the New Waterpump and Install the Pump. You can do this either with or Without the Fan already put back on. Please Rate My Response! Thanks!
