Thanks for the tip Harry, I never heard of using PH , but this makes sense. I
know you can also use a multimeter to check for electrolysis. 300mv and below
is OK. Ground the black lead to the (-) battery terminal and put the read lead
in the coolant. Take a reading with the car off, if it is above 300mv - time
for a flush and new coolant. If it is below 300mv then start the car and let it
warm up. If the reading goes over 300mv, time to flush change the coolant.
