Six blade metal fans were stock on at least late1967 cars.

We have always experienced higher engine temperatures with higher percents of
anitfreeze (I think that is one thing that ulix is saying). Recently flushed
our cooling system and changed from 50/50 anitfreeze/H20 and Water Wetter to
25/75 anitfreeze/H20 and Water Wetter. Our operating temperature has dropped
from 180-190 down to 165-180 with a 160 degree thermostat. Of course the
entire change may be just due to flushing the system, it had considerably more
sludge than I expected.
