Test is simple. digital volt meter, car running, neg on battery, and positive probe in the radiator fiuld with out touching the sides. Directly in the fluid. check both ac and dc on the meter. if the voltage is greater than 0.3 volts, it will eat the heater coil up. Sound crazy, but its true.. AC Delco has a great article on it. search heater core failure due to electrolysis.
when I pick my ss up from the shop next week, I am taking my volt meter with me.
Interesting and informative... be sure to share your results, after you get the car back.
