Great news, Steve. Glad to hear the problem was fairly easy to fix.
Clearly that shows us that we need to be selective about the evaporator
cores we choose. I guess one test is to poke a wire down each side and see
if it makes it to the bottom {:>)

Subject: [FlyRotary] Evapora5tor Core Problem Solved
I went to the airport today after drill out the blocking plates In my
evaporator cores. After installation, I filled the system up with
coolant,
and ran it for a couple of minutes. It was barely warm, so I opened the
header tank back up, and topped it off again. The rain let up for a few
minutes, so I pushed the plane out, and taxied it up and down a few times,
and also did a short run up to 4500 RPM's. When I taxied back after 7 or
8
minutes, my coolant temperature was still only up to 180.
The cores are consistently hot from top to bottom, and also the air purged
out much easier.
It is amazing how well it works when you're using the entire core, instead
of just 25% of it. I can't believe that I messed around with it for a
week
before getting to the bottom of it. It seems so simple now. Thanks to
everyone for the help.
Now all I need is some good weather to take it for a flight. We needed
rain, so I do appreciate our Florida friends sharing their hurricane
leftovers with us, but now I'm getting really tried of the rain.
I also have to go out of town for my youngest daughters wedding this
weekend, so probably Monday evening will be my earliest opportunity to see
how the new cooling set up works.
