Check Guages/Voltage drop 2000 Dakota Water Pump Bearing

2000 Dodge Dakota 5.9l v8 108k miles: Changed Alternator thus far.
Symptoms: Back a few months my truck began squealing like a belt slipping and it would come and go. This progressed to the "check gauges" light coming on, which then progressed to the voltage meter dropping to zero.
I changed the alternator but that did not make the problem go away.
I can sometimes drive for a day or two without it acting up but once it starts I have to turn of the ignition and restart to have the light go out and the volt meter to regain 15 amps/volts? This is very frustrating and I am afraid of the computer being at fault $$. The belt tension is good and the tensioner pulley has good spring tension.
I did notice while trying to resolve why, that the serpintene belt seemed to walk towards the block on the fan pulley every so often. After looking closer it seems that the belt is not walking but the fan/crank itself is moving forward towards radiator, just a little? Now I am really scared!!! could someone please help me out?
Thank you very much.

Is this using a water pump driven fan clutch like in the pic above? With engine off you could probably just wobble or carefully encourage that motion you noticed and see if the clutch or the water pump is causing that. If the belt can't stay on track all bets are off for it working for the other assories. HEY - that can fall right off and cause a ton of damage so get after that!

Tom,
Thanks for the reply. I am glad for any advice. Today I checked again under the hood and there was anti freeze being misted about by the fan. This is new as of today. Although I have noticed the hot smell, sort of anti freeze smell when I exit the truck but could not figure out where it was leaking.
So Tom is this my water pump that has/is going out? I can wobble the fan and yes it is on a clutch. What do I need to do? I am guessing a bearing is shot?
Thank you for the reply and any further help you can be. The weekend is here and now is the time when I can work on the old horse.
Best Regards,
Greg

Ok: The wobble with a leak IS the water pump with almost no doubt. May be hard to tell but the clutch could be bad too or even wobbled itself and think seriously about replacing both.
I don't have the software for a diagram of this job so take a look - I'll try as best I can if you want to tackle this. Just say so - I'll do some digging for info. I don't know this engine specifically. Do you have the sockets and wrenches for this?
Just say if you want to do this and we'll kick in,
Good luck,
T

 Ok: That should be the pump. I'm just searching parts at Autozone for pics. No repair guide there for this but that pump doesn't look too hard - famous last words!

Thanks so much Tom. I picked up a pump yesterday at Napa so this afternoon I will work on the bugger. I have a Chilton book for my truck so I am pretty sure I should be ok from here out. I sure do appreciate your help.
I wonder if I did not need to replace the alternator after all?
I will let you know how things go. Thanks again. Good helpful people like yourself are out there it is just finding them. Thanks
Greg

Ok: Good luck. I did move the whole thread to "engine troubles" so if it confuses you join the club as it confuses me to do that sometimes. Also changed your first subject line to state what it is now for surfers

Tom- Thanks so much for your help in diagnosing and then the tips on replacing the water pump on my Dodge p/u. Saturday afternoon I began around 5:00 pm and finished at 10:00 not bad for me.... Everything seems OK and my heater is even performing better! Needed it here yesterday and today -8* F. Brrrrr
There is still a squeal when the truck warms up and the rpm's are raised not sure what is making that yet but I also have yet to investigate.
Thanks again and God bless you for your kindness.
Best Regards,

Good for you for getting that job done. For the squeel: It could be anti-freeze on the belt, belt itself may have sustained some trauma from the wobbling pump, belt tension not enough due to tensioner or stretched belt?? If it is in proper track and seems ok just try some spray like WD-40 on it - if that shuts it right up for a while and everything else is fine just do that a few times or seek out a belt made to be quiet. They made them and it isn't to cover a problem but some vehicles just get fussy about that.
Good luck - stay warm!
