I took my radiator right out from the start, and used a good impact on it, was stubbern but it gave in after a bit. cant remember the thread direction, wonder if there is a manual that you could check for that ?

I might have to dig mine out and check it if you dont have any . . . . . .
yeah, the hard part is holding the pulley, we had a strap wrench on mine and a breaker bar and it just kept slipping.
Even though the VG33 is considered an interference engine (meaning the valves "can" make contact with the pistons) , a lot of people have said that in most cases they do not make contact.
guessing the odds are your no where near Ashland Pa huh ? just a thought............
