Bill,

 

This is a good point and something I have been thinking about.  The added NPG was 100% PG but there was obviously a little bit of aquious PG left in the system.  I tried to burn it off during my hour long ground run, but the temp never got very high (toped out at about 180).  That little bit of water may have boiled over and forced out the evans...

 

Someone else brought up the 7 psi cap with altitude.  That is also a possibility - actually a combination of both.

Dave,

When you switched to Evans coolant, was it at 100% Proplyene Glycol?
