I was thinking about changing mine also, but now I will wait awhile.
Have any of you used that Redline Watter Wetter? If so any results?
I just did the test on my 01 with 28,500 miles. I got a reading of 0.20 volts.terry schulze said:
There is a simple test for EME. Take a multi meter & put it on the lowest DC voltage range. Stick the positive probe in the coolant at the radiator cap. On your corvette stick the positive probe in the coolant in the reservoir. Hint you may need to use a piece of bare wire or other metal extenton to reach the coolant. Then touch the negative probe to the engine. If EME is present the meter will read between 0.5 and 1.75 volts. If the reading is in this range change the coolant. This is not stray current from the electrical system. It will work even with no battery in the car.
This test is so easy to do I will be doing it occasionaly & if it starts getting near 0.5 volts I will be off to the store for some Dex Cool & distilled water! Even if you keep passing this test do not ignore the time or mileage change criteria. The organic acids deplete over time and need to be replaced. To be safe I won't be waiting 5 years to change mine. I checked my 2002 Z06 last nite. The car has 500 miles on it. I got a reading of 0.10 volts.

any tips/hints on doing this?
any link to tech page on how to do it?
should you always do a flush before replacing?
is it possible to do without lifting car?
