Re: Overheating Stumped...

One time I had a water pump where the fins (that are pressed onto the shaft) were not turning. Dont know if it was a manufacturer screw-up or not but I after I removed the water pump I could spin the fins with no effort on the shaft. Is the thermostat opening? Just a thought........ Bill

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??
