Justin Cornell's GP38-2

I am revisiting a couple of projects I did way back when and wanted to completely finish a test I started by adding some newer options to the original model.
I noticed this time round that the radiator and dynamic fans are not working. ( I have Justin's original zip file )
Did they ever work....? I cannot recall....
...and if not, was there ever a fix.
Thanks..
