What bothers me is Evans has about 20% less heat rejection capabilities than conventional water/glycol. Even though your car isn't boiling over it still can have the problem of running too hot. With elevated cooling system temperatures engine clearances change, especially with an aluminum block/head engine.

I did a good bit of Evans research when my engine was "cooling challenged". I elected to really fix the problem, rather than an ineffective band-aide.
