I'm Not sure who jimharvard's snide remarks were intended for so I'm curious jimharvard, where did you get your degree? If your shot was at me, my degree came from Cal Poly 1972 not a slouch school. So beyond being able to capitalize and italicize what do you bring to the table?
BillGrissom, I didn't see where anyone said anything about water flowing too fast through a radiator, etc., and I certainly wouldn't challenge your expertise in heat transfer. Having said that though, I do know that if I don't use a thermostat in my sprint car to throttle coolant flow it doesn't perform as well.
And, I'm outta this thread.
