I'm still fighting overheating problems with my '75. My car has < 1000 miles
since I finished restoring. It has a 4 row radiator, flowcooler water pump,
electric pusher fan, and Tanner's compound scoop. Everything is new except
the engine which I took out of another car with 53k miles on it. On a recent
drive on a 90 degree day the temp gauge got to about 210. When I shut it off,
it continued to run for a minute (dieseling).
I used an infrared thermometer and measured 195 at the top of the radiator,
165 at the bottom, and 230 on the top of the intake manifold. I'm thinking
that the engine might be plugged up based on the large temp difference between
the top and bottom. So I'm thinking of flushing the block. Which is better,
to get on of the flush kits and do it myself or take it somewhere and have it
"power" flushed?
