Changing to Evans Non-Water Coolant
I've been wanting to switch to Evans for a long time, as it works great in our race car, and should be a no-brainer on the street. It would also bring corrosion to an end.
But I have some questions.
First, has anyone done this? Forum searches did not turn up any results for me.
Second, the effectiveness of Evans requires less than 3% water in the entire system to be effective. They have a hygroscopic fluid which absorbs residual water, but there's no way it is designed for, say, a liter of it.
Which brings me to my problem....
Has anyone figured out how to drain the heater core?
The only solution I can figure out is to perform multiple flushes at temperature with the Evans solution, and measure the results with a refractometer until it gets under 3%. But getting the water/glycol out of the heater core is the major issue, I believe.
Any help, insights, and advice is much appreciated,
