Bud.... This also won't give you an accurate temperature! Recall:
PV = nRT
Temperature (T) is inversely proportional to P (pressure) and V
(volume). If you leave the radiator cap off, the system is not
pressurized thus Temperature will be different than if the system is
pressurized as it normally would be.
Big question which I alluded to the other day when Frank had his
problem - "Is a spridget cooling system pressurized??" If it isn't,
you are okay, but I'm thinking it has to have at least some pressure
in it due to expansion from heat and the fact that the system is
closed.
