I have seen 2 different type fans on 54 chevy truck 235's... both are 18in diameter w/4 staggered blades , but the blade widths differ. Is one for passenger car and the other is truck. or is it thiftamaster vs loadmaster vs jobmaster?
Cannot find anything in the old literature and was curious why the difference?
Thanks,
-Paul

You'll see at the link above that there was an earlier, different, 4-blade fan. It is highly likely that the different 4 blade fans you have seen were from different years, pre-54/55, 54/55, and post 54/55 (however, later 4-blade fans had a larger diameter). | | | | | Joined: Jul 2011 Posts: 24 New Guy | | New Guy Joined: Jul 2011 Posts: 24 | Tim, Thank you, this was a huge help.  Once I had a part number to reference it was easier to determine which fan was which. Much appreciated... Thanks again, -Paul | | |
