When our 1964 Corvette coupe rolled into the garage it had a functional cooling
system, but the generic aluminum radiator didn’t offer proper fitment. It was
physically too tall for the car and the hose outlets were not quite right.
shop. The improved stock-look aluminum
radiator and flex fan is certainly capable
of cooling this modified small-block, as we
have been pleased to see the temperature
gauge staying at 180 degrees. In addition
to the improved cooling capabilities, the
new components cleaned up the engine
bay nicely. Take a look at our cooling sys-
tem overhaul and use the tips and tricks to
keep your C2 cool, whether it’s on the high-
way, sitting in traffic or blasting down your
favorite backroad. VETTESources

The original fan shroud was in
pretty bad shape before the univer-
sal-fit radiator was installed, but you can
see where modifications were necessary to
accommodate the radiator hose outlets.03
After draining the fluids and undo-
ing the less-than-desirable cooling
system repairs, we were ready to remove
the generic radiator, electric fan and
hacked-up shroud.04
Since our new DeWitts radi-
ator is a direct-fit piece, we
whipped out the Zip Corvette catalog
for some standard replacement parts.
First up was a pair of new radiator
cushions (PN WS-333) that fit into the
original lower radiator mounts.05
The radiator is DeWitts’ HP
Series (PN 1249063M), which
features all-aluminum construction
and two rows of 1.25-inch tubes and
offers 25 percent more cooling capac-
ity than stock replacement radiators.
We ordered ours in the “Black Ice”
coating for an original look. The orig-
inal-style dowels fit nicely into the
new rubber cushions.
