not a good suggestion in my opinion
Well it wasn't meant to be taken literally, but used to illustrate my point that regardless of how cold it is outside, without a steady stream of "cooled" coolant, your motor will eventually exceed the operational temperature limit (in the case of a 1946 Chevrolet, thats about 212 degrees)
The fact that his engine temp dosen't get above 165 suggests that the engine is indeed getting "fresh" coolant.. if it wasn't, it would overheat.
My '46 1/2 ton has an aftermarket temp gauge installed under the dash, and even on warm days hasn't gotten much warmer than 130.
