Hey guys I havent been on in a while and have forget to tell you all that my friend and I installed our governor springs and wow...what a difference it made. Anyways, I have noticed some coolant dripping from below my water pump and can only assume that it is in fact the water pump. So i bought the water pump from napa for 68$ and now am wondering if there is anything that I need to know before going into the switching of the two. It cools fine so I am guessing its just that **** gasket so Im not exactly happy about switching it out but he at least I will have a new pump. Anyways, what all do I need to do to allow myself room to work on the pump? do i need to take off the fan? i have never done a water pump before and am not a very experienced mechanic so any tips will help and as always the tips are much appreciated....Austin

the gasket is a round large o ring. not likely to leak. probably the shaft seal of the pump.
easy as pie. remove the belt. take off the 2 bolts that hold on the pump. remove pump, install in the reverse order. bleed coolant system. away you go.
its the blue smooth pulley in the lower left of the pic[IMG][/IMG]

so the fan will not need to come off? so is coolant going to spill out of the old water pump housing or is it controlled by something internally before it comes out? what im asking is how much coolant will i most likely need to add? i realize that an amount will come out with the actual pump itself. what is involved with bleeding the cooling system?

all of the coolant will come out. depending on the diameter of your fan hub pulley, you may be able to get the top bolt out with a combo wrench. my b series motors that i have changed the pumps on are industrials, and accessibility is alittle easier than a truck. hope it helps

Just drain the radiator, then you won't have coolant gushing out all over when you pull the pump.

The fan stays on, you will spend more time draining and refilling the cooling system than actually changing the pump - it's that easy.

You don't have to bleed, just fill it slow.
