My auto is losing prestone. This seems to have started just recently. Had the radiator pressure checked, for any possible leak around radiator and hoses and no leaks were apparent. There was a test done for the head gasket by analyzing the prestone in the radiator, and there was apparently no sign of this issue. There was also no sign of prestone in the oil. With the engine running, I have seen a little vapor puff on the passenger side of the engine from time to time. I was advised that it could be a frost plug or a water pump leak. The car has approx 180,000 miles. There is a sign of leaking around the engine, but no apparent sign of prestone on ground. I am losing approx a cup or so a day, however, recently the loss seems to be less than that. I look forward to your comments on this matter. Thank you for your help. Mike
