Have any of you who use two tanks for the seperation used alcohol (or windshield wash fluid) for the intercooler system? In the possible event of a leak in the intercooler core I would much rather see water and alcohol leak into my engine than eytheleen glycol prrmanent antifreeze. Old cars that used alcohol used 7 lbs pressure caps and 160 degree thermostats. The alcohol would boil away with a 180 degee thermostat. I do not think the intrrcooler water would normally exceed 160 degrees so it would not normally boil and therefore would not push water into a recovery tank.
