Are you sure that the electric fan is turning in the correct direction? I've
talked to more than one hot-rodder who had it turning backwards by mistake
and wondered why his car overheated. My '74 1500 never overheats, even here
in Texas, with the same radiator you describe. Was there really a larger
radiator?

I was wondering what the measurements for both the narrow and full-width
radiators for the Mark Iv's were? I apparantly have the narrow radiator, a
seemingly original Stanpart unit that is 14"x11", and stock looking brackets
that attach it to the radiator ' U ' mount.
With no overdrive, at 65mph (4500rpm), 7500' elevation, and 95 deg temps
(not now, during the summer...) it is just on the verge of overheating, and
exhibits the usual stumbling, hesitancy, lack of power you get at that
point. An aside, it actually corresponds with the temp guage, which is
nice!!!
My 10" electric fan covers almost the whole front of it, and between
that and the regular fan, moves a tremendous amount of air, but I don't
think the volume of coolant in this small radiator is enough (under 1.5
gals.)
It appears that somewhere along the lines it may have received the
less-than-adequate radiator. Does anyone have the measurements by chance???
Thanks!!!!!
