Your new water pump might be designed for an electric fan truck if it's not threaded. For the fan on your current truck, sometimes putting a big pipe wrench or something similar on the fan nut and whacking it with a mallet or sledge hammer will do the trick (have to have the belt on it still to keep the pulley from turning). I've heard of people taking power chisels and hitting the nut directly with them to break it loose as well.

I found the easiest way is with the pump on the truck and the belt on to hold the pulley. Put a big crescent wrench on the nut and give it a hit with a hammer.

I use the blade holding tool that came with my makita grinder to hold the water pump pulley. The pulley has holes in it and just slip one of the teeth on the tool in and then apply pressure while I use a 24" crecent wrench on the fan pulley. Comes off like butter....... and then goes in the trash for e fans lol.

Spray penetrating oil on the nut/threads. Then stuff a towel in the sepentine belt area to lock up the belt. Then put a huge crescent wrench on the nut and take baseball bat swings at it with a rubber mallet. That's my method. The key is having the crescent wrench tight on the nut.
