What size wrench does it take to remove a fan from 99 land rover?

you need a 36mm open wrench. sometimes its hard to undo it try to tap it with a hammer if that doesnt work you need to find another tool to hold the water pump pulley but you can also use a big screwdriver to lock the pulley, i hope i helped you if you need another question my email is snooker_1813@hotmail.com
