Eliot- At one o'clock, the temp must be at least 115 deg C . Isn't that kinda hot to be running a car with aluminum block and heads? I became concerned when the temp gauge got past the 1/4 scale point (85 deg C). Are we saying I don't have a problem?? I like those, they are the easiest to fix!! Frank Santoro 1990 V8 Kingsville MD
