Water Pump Removal
Can someone give me the step by step on removing a water pump from a 74' 350 small block. I got the alternator belt off and the ac belt off but cant get the fan off.

No couldn't feel any bolts from the front of the fan (facing radiator). How do you get these off? Is it as simple as sticking a socket in between the blades or do I need to take the fan cover off?

there are 4 studs that stick out of the water pump shaft wheel, that go through the W/P pulley and hold on the fan with 4 nuts. Remove these nuts, and carefully remove the fan. do not nick the radiator. You remove them with a open end box wrench, as space allows.

Wow I feel utterly stupid now! Thought you meant facing radiator because I tried those but the whole thing moved so I figured that wasn't it. I guess I need to keep that thing from moving somehow while I take the bolts off... Thanks though guys I was really lost there and this helps tremendously.
All right.. To get the water pump out do I have to disconnect all the brackets holding up the AC and the Alternator? It looks like some of the same bolts are used but not sure.. Thanks for pic RunningMan.

I don't remember which brackets have to be removed exactly, did the job last year, but, if you study the front of the engine, it will become pretty obvious what is going to need removal. don't forget to drain the radiator first. C.

Drain the radiator first. If the car isn't overheating, it still has most of it's coolant. If your radiator doesn't have a drain-**** fitting, just remove the lower hose from the radiator [with a bucket underneath].

1-remove everything attached to water pump
2-remove water pump
3-re-assembly is reverse of dis-assembly
Before returning your old pump,make sure the new one has the studs for the fan,if not you'll have to reuse the old ones.They can be removed by using two of the nuts jammed together on a stud.I always put a thin coat of silicone on the gaskets to help seal it up and to hold them in place when getting the pump into position.
While you're at it replace all the belts and hoses,its a lot easier now than at the side of the road later...

It is easier to remove the fan blade before you remove the belts.
You can also use 2 wrenches. Use one on of the nuts, to hold the fan still while using the second one to remove one of the other nuts.

Some of the parts transfer over to the new water pump. The four little bolts that held the fan on they transfer over, the Inlet And outlet on the Heater hoses They Im pretty sure transfer over.So dont get rid of the old one just yet.I always keep my old parts I just Hang them on the wall of the garage I store My car in.
