He said that most people would actually want MORE air to be fed to the radiator for better cooling...At that point, I decided to keep my mouth shut. I can understand increasing the grille opening if you're into HIGH performance, but this is a freaking ECHO meant for FUEL ECONOMY !
Boy am I glad I did not finish the lower grille block yet.. I wouldn't have been able to withstand his diatribes.

...BACK on topic
I will be painting the lower grille blocks today. Stay tuned.

Perhaps his ASC training failed to share with him the part that the radiator cap plays with respect to system pressure,and that it would simply 'vent' into the overflow receptacle and be sucked in later when cool.
