did you try all the troubleshoot steps in the Service manual outlined on page 21-94? There are a few suggestions like a relay replacement and so on before you have to replace the fan.
Looking at the SM, maybe you can remove the front grille to get access to the screws that hold on the hood latch (if it needs to be removed) and to access the screws that hold the fan shroud assembly on.
I'd start off with the grille/steps listed on 10-10 and stop after step 8 and then jump to 12 or 13 depending on how hard it is to access the screws.
Id recommend you buy new honda type 2 coolant if you are going to drain the radiator.
