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.
I ducted my radiator thoroughly when I blocked 80% bottom and all of the top... no air comes through the grille that does not get forced through the radiator. My running temps are in the mid 190s, sometimes up close to cooling fan temps of 203* on the HOTTEST days in the hotter driving conditions. This is virtually the same cooling I have seen for 10 years (oh, and two years ago, before the blocks, a radiator tank ruptured due to its being 11 years old and due for meeting its maker, so to speak).

Just make sure you leave a significant opening, mine is the width of the radiator and right in front of it, and make sure you duct it.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
