Sorry, It takes a $40 tool to do this. The tool comes in two parts. One is a two prong tool with a slot at each end, this is where you connect it to the 4 bolts on the fan. The other is the wrench part. put this on the large nut behind the fan. Push and pull to loosen the fan nut. I got mine at advance auto.
The belt needs to be removed. The fan will have to be unbolted and removed, you may have to remove the fan shroud as well. The water pump can then be unbolted and changed.
The water pump on a Chevy Blazer 4.3l is on the front of the engine. The Fan and fan shroud will have to be removed to gain access.

If you look at the big fan on the front of the engine, The water pump is what the fan is bolted to.
You can tell where the water pump is located by finding where the mechanical fan is bolted to. If you want to change the water pump, the fan and fan shroud must be removed.
First thing that you will need to do is remove the raidiator, making sure to remove the lower water hose from the radiator and all other hoses connected to the radiator. Next you will need to unbolt your power steering pump and the front mounting bracket and remove all fan belts. Unbolt the alternator bracket from the engine block and front of the water pump. Unbolt the fan belt pulley from behind your fan. The best way I have discovered to do this is by placing a screwdriver between one of the bolts and use it as a lever. You will find 4 10mm sized bolts through the pulley to the water pump. Once you have unbolted the pulley, you are ready to unbolt the water pump. You should be able to find the 4 water pump bolts and unbolt the water pump now. The hard part is to now remove the fan off the old water pump and bolt it onto the new water pump. This is where I'd usually take it to the mechanic and get HIM to remove the fan from the water pump. Now it is as easy as reversing the previous steps and put it all back together.
fan clutch is built into water pump,u have to get new water pump.
What about it? Remove the fan shroud, remove the fan itself, unbolt the water pump.
There is no fan on the water pump on that vehicle, only a pulley that unbolts.
Look at the water pump and see if a fan is attached to it. If so it has a fan clutch. If nothing connects the fan to the water pump then it is a electric fan. Some do, some don't. It depends on what options the Jeep was built with.

Take out the fan cover, then remove fan, then the hoses, then the water pump. you can do everything from the top.

Look at the front of the engine at where the fan assembly attaches. The shaft of the fan attaches to the water pump drive pully. Right behind that pulley is the water pump.
