Question:

97 dodge van 3.9 water pump?

removed my water pump to replace it. i have the fan and clutch assembly still attached...i have no idea how to remove these...the fan clutch has bolts that hold the fan to it...and i did remove those but im just not sure how to separate this assembly...my water pump pulley has 4 holes...and no bolts so i presume it's pressed on...and there looks to be a very large nut between the pulley and the fan/clutch assembly...any help would be appreciated on this...i'd much rather go to the parts store w/ the old pump instead of guessing.....thnx in advance...

Answer:

The fan has a large nut that needs to unscrew off of the water pump. It is easiest to do that when pump is still on engine. It should be standard righthand thread.
Corrosion is now holding everything to the pump. Use a screwdriver to help separate them. Here is a link compliments of Auto Zone showing how to remove the water pump. You will note in the picture that the pump has a shaft sticking out of the front. That is holding the clutch and fan on. Earlier I gave you the wrong link. This is the correct one for the V6. The others were for the V8s They mention to remove the fan before removing the water pump. The fan should be bolted to the clutch in the manner you say. If you grasp the shaft on the pump, the fan and clutch should rotate freely. If you pulled the 4 bolts off the pulley, the fan and clutch assembly should come off. The pulley should then fall free. Is anyone else helping you with this and they already took the bolts out? If not you must have some alternate water pump that Chrysler failed to tell everyone about. Is the large nut against the pulley or the fan clutch? I wish we could talk on the phone. Get a mallet. Put the pump on a clean surface and use the mallet to tap the pulley on one side then the other. Hopefully this will help work this off. Once you get this off, you will see it should look like the pictures I sent to you. I just sent you another link that has 3 different ways they have the fan mounted to the water pump. Yes, there is a large nut holding the clutch on. It says it is a right handed nut so be careful taking it off.
I,m with JOHN R in this one, confirm your radiator fan seize is working and not purely unfastened wheeling all of the time and additionally confirm that there is no air trapped interior the cooling gadget.With engine off crack a heater hose unfastened close to the heater center and pour anti freeze in until it starts to return out the disconnected hose. And the cooling fan could become noticeably louder whilst the engine is heat and in case you shut the engine off it is going to experience stiffer to coach than it does cool. sturdy success.
