Glad to see someone picked up on the hint!

One caveat, though:  There's no reason to turn on the heaters full 
blast.  The Delanair systems have the coolant flow to the heater core 
wide open during most operation, including A/C operation; it's only 
during the most extreme call for full cooling that it ever turns the 
heater core flow off.  So, don't bother with turning the heat on; 
just drive normally.

While I expect that installing this screen may catch a lot of stuff 
and possibly result in longer times between radiator rodding, I'm not 
sure it'll be as effective in protecting the radiator as the Gano 
radiator hose filters.  For one thing, the typical chunk of plugging 
material may randomly decide to make its way to the radiator FIRST 
and jam a tube before it ever gets to the heater circuit.

The other problem, of course, is that this is a tiny screen indeed.  
Since it is in the heater core circuit, it essentially becomes a 
"bypass filter" so it getting plugged doesn't hurt anything.  
However, I suspect that, at first anyway, it might get plugged REALLY 
fast -- like in the first 5 minutes of running.  And it might do that 
two dozen times before the circuit is clean enough to make it to the 
store and back without losing heating capacity.
