What Chris said, me too. Turned out my rad had most of its tubes plugged, o=
nly at least I didn't have to fix it at the track. Local radiator shop diag=
nosed it, and "rodded it out." That is, he took the top off and ran a rod t=
hrough most of the tubes. Some were so plugged he could not get the rod thr=
ough, but it was enough to fix the problem. This was actually the original =
radiator in my '64 Spitfire and then some 25-30 years old. I later replaced=
it with a lighter one for weight.

Hi,
had this once on a fellow racer car.
Turned out a clogged radiator that closed few remaining open pipes on tempe=
rature.
We replaced the radiator on the track (someone brought a new one) and from =
that time never a problem again.
Cheers

Subject: [Fot] Coolant conundrum
I'm having cooling problems.
Need help being convinced that I have to do what I don't want to do.
Brand new short block, same old head, water pump, and radiator.
Over three trials, the engine will run fine and warm up with radiator hoses=
and radiator warming properly. Then the hoses and radiator will cool and c=
oolant temp will spike to 230+. Radiator cold with sky high coolant temps.
Two more clues, hoses seem to pressurize very quickly and when I opened the=
radiator cap this morning (after cooling all night) pressurized air and co=
olant shot everywhere.
No thermostat and I have confirmed three times that system is completely fu=
ll
Seems I have combustion gases getting into coolant and then bubbles eventua=
lly removing pump prime.
Don't know what else it could be.
Given the apparent direction of the leak, is there any use in trying some "=
stop leak" product?
Is it time to pull the head again to look for warping or gasket leak?
I suppose it could be a cracked cylinder, but this block has been checked b=
y two different trusted engine machinists.
Desperately trying to get to the RunOffs, Anthony.
