98 C1500 clutch/fan removal

I'm switching 305 engines in my 98 C1500 but can't get the clutch/fan of the old motor. I removed the four bolts which I thought held the assembly to the water pump, but none of the parts including the pulley would come off the water pump. Is there a trick to remove the pulley, fan, clutch? Thanks.

The big nut on the clutch fan takes it off.

Thx MT, I went to autozone but their instructions are incorrect as they are for the older style setup used for decades. I did get the pulley off; it was just stuck.

You are welcome.
It gets tight.
I always whack it with wrench on it and whack the wrench with a hammer.
Good Luck

I ended up taking of the complete assembly with the water pump. The wp looked to be a recently installed GM pump so I'll just install the whole assembly on the new motor.

More than one way to skin a cat.
If you ever have to take it off they make a tool to help or most of them I hit the flat side on nut with a chisel to loosen it up.
A good air chisel will loosen them up in a few seconds.
Good luck
