I think the t-stat opened as it was showing flow. Can't verify the
blades on the water pump right now but it doesn't make sense that the
water pump would be fine one minute and screw up the next like you
describe (although not totally not out of the realm of possibility)
Gimme the $380 I spent for the 4-core radiator and I'll gladly put a
3-core back in it.

Run it with no thermostat and see what happens, maybe the thermostat is

Subject: Overheating Stumped...
So I'm trying to diagnose the issue that's causing my new 4-core
radiator to make the car run hotter than with my previous 3-core
radiator. Not only does it run hotter at cruising, but it starts
getting hot IMMEDIATELY upon stopping at a light to the point of being
scary.
Basically the only thing I changed id the radiator. Car is 318 Poly
with a mild cam, 7 blade fan, fan clutch (confirmed working), no
shroud (never had one), now new 180 deg high-flow t-stat, spring in
lower hose.
The symptom I cant figure out now is...after testing things today and
keeping an eye on temps w/ a laser thermometer, I turned it off to let
it cool and scratch my head. When the rad, and upper hose had cooled
to ~165, the lower rad hose was dead cold. I pulled it off and there
is no restriction in the hose or the pump. I looked in the water pump
from below and don't see anything up there either. It's not leaking
Any thoughts??
