water pump problem
Ok
So yesterday I noticed my coolant was leaking from behind my crankshaft pulley. I cant see under the waterpump pulley but I am thinking there is a weep hole there and it has started to leak (about 20 drops a min.) indicating my waterpump has gone bad. Does anyone have any suggestions? If I do have to replace it I will do a thread on how to replace it beacuse I couldnt find one.

Water pump is pretty easy, just be careful not to strip stuff. Yours is still good, the seal just went out of it, it sounds like, however in this day and age you must replace. Good time to do a new thermostat too and or a coolant flush.

it shouldn't be too hard once you get yourself a suitable fan clutch wrench. oreilly has a whole set of different sizes you can borrow as a set. the ones that are sold as being for ford, don't fit. one time when that wrench wasn't available, i got it off using a vise grip style chain wrench i bought at harbor freight. leaving the belts tight, i wrapped that sucker around it and locked it down tight, then took my hammer and beat it till it came loose.
once thats done, remove all the belts and get into it. i haven't done it myself, so i won't try to give you too much more detail

If you have an air hammer you can put it on the edge of one of the flats, leave the belts on, and it will take that fan right off no questions asked. Just be careful not to accidentally hit the radiator the few times it slips off the big nut. That's how I have done every threaded fan for the last 10 years. Working in garages all my life, that's a lot

X2 on doing the thermostat along with the water pump.
Flush out your radiator as well as the block with both thermostat and water pump removed.

I built this out of some 1/4" steel I had laying around it works awesome it is about 2' long, really easy to make just used a cutting wheel and a vaneer caliper. the angled piece you just put one of the bolts for the fan in the hole. pull opposite ways and wahlah.

i'm pretty sure he was referring to the shaft seal not the gasket. but i've never seen the water pump shaft seal sold as a separate item. i agree with you that a new water pump is the right answer.

Be careful when taking pump off of seperation plate/ crankcase cover/ piece of metal the water pump is sealed up against, to not break the gasket between the plate and the engine block... I did it huge PITA! I had to remove IP, half of the turbo kit, harmonic balancer, radiator, "f"ed up the oilpan gasket, need new crankshaft seal... dont do it!
