I stick a small "Inspection mirror" up
through the AN-16 fitting with a small light shinning on the
mirror. (I think next time I will wire a small LED to the head of the
mirror - would make it much easier) I then run the mirror up and
down the side tank and rotate it at intervals looking mainly at the condition of
the small 1/8-1/4" dia cross tank tubes. I look for blockage or any
indication of scale/gunk. Thus far I have found none.
I am not certain but in thinking about it I wonder
whether the tank orientation as well as entry/exit points used could make a
difference. Both my entrance and exit ports are on the bottom leave
no good place in the side tanks for sediment/gunk to settle. If a person
used a top entry exit, I would think it would be more likely to trap sediment on
the bottom. Just speculation on my part of course.

Ed,
Sounds like a
rational plan. So, how do you go about “inspecting” your evaporator
cores for blockage?

I agree,
trying to fix the problem that isn't there can be frustrating in the
extreme. In Perry's case, I certainly understand the use of the
"Radiator Stop-Leak" if you are out and need to get home as an "emergency"
measure, but on the other hand I don't think a screen would necessarily have
made any difference in his case. Once you put something like that in
your system then you have compromised it to a degree.
But, then that
is what this is all about - some perceive risks where others do not and hence
take a step to alleviate said risk. However, I can see some folks using
a screen and never having a problem (just like some of us flying have not (at
least thus far) had a problem with gunk in the coolant system) and others
using a screen and perhaps getting flow restriction or stoppage and others
(who inspect regularly) showing where a screen has perhaps stopped gunk from
flowing into the radiator..
My personal
viewpoint is to minimize the number of components, but will readily admit to
have screens and filters in my fuel line - so perhaps the having same in the
coolant lines is no different (at least in concept).
