How do I know if its my water pump?

97 gc 5.2 ---Lent my jeep to my friend and and got a call 2 hours later that it was spewing coolant. I didnt get there till the car was cool so i dont know if it overheated. Waterpump still spins fine but alot of coolant was coming from where the pump bolts in. The waterpump still spins fine and seems ok to me. Is it possible that the seal went bad and thats all that needs to be replaced.
Also what is the best way to replace the hose that goes under the ac pump from the water pump?
Thanks

I guess you will have to fire it up and wait to see exactly were that water starts leaking from. Your water pump is eight years old. It probably can not last much longer, even if it is not the issue.

I have checked with the car on. It leaks from where the pump bolts in. Is this necessarily my water pump though?

It typically does not leak from around the housing unless the housing is warped. There are two weep holes for the water pump. If the internal bearing is bad then coolant will leak from these holes. Either way you will need a new water pump.

A torch will not help. The geometry of a circle is working against you. You cannot pull directly straight out, without a pulley puller. Jeep pulleys are very cheaply made, and can bend easily. Soak the sh_t out it over night and try to drive two wedges behind it. Something like door-stop wooden wedges can sometimes work. Make the wedges out of 2x4s if you have to. But the pullers are really cheap to purchase and you can use them on many different parts.

I 'rented' a puller for my fan clutch at a parts store her in town. Charged me credit card for it, when I returned it the next day they refunded my card. Very painless. If it had been a better quality puller I'd probably would have kept it.

I would not take the disk off of the shaft. The pump is very cheap, and it comes with a new disk. If you apply pressure on the shaft, then it will surely leak in the future. I suspect that that is what is leaking now via the weep hole. I would hate to get it back together only to find that you really need a new pump. Prophylactic pump replacement is a good thing.
