Anyway, link below shows a special tool 115050 when detaching fan wheel from water pump union nut.

Is there any other tool I can use to improvise?
I bought this one --> here. Before that, I just made my own by grinding a semicircle out of a piece of metal and drilled/filed the holes in the proper places to grab the water pump pulley bolts. Remember, the water pump pulley / bolt for the fan is reverse-threaded, so you will turn clockwise to loosen.

Try to wiggle the water pump pulley lightly by hand; if it's sloppy, replace. If it's been a year or so since you last replaced the belts or if you notice cracking along the ribs, replace the belts.
