    I installed mine after the rads and recommend it as well, due to one major factor that hasn't been mentioned. These pumps are plastic and while their max temp limits are above our operating range, prudence would dictate locating them on the cool side of things. 
 
Good point.  I knew I wanted you around for some reason :-)  
 
    As for your idea of one for each rad, I kinda like it. 
 
I think I've decided to give it a try.  As I mentioned before, there's almost nothing to lose, since the only difference between the two methods is s simple plumbing change.     
 
 Ps. Can you send a pic of the check valves that you plan to use.

I'll add that to my list of tasks for the next time I go to the hanger.  There really isn't much to see though.  It's just a bronze valve that's about 3 inches long, an inch or so in diameter, and 12 oz in weight.  The burst rating is 400 psi, so it's just a bit more robust than I need for coolant :-)

Cheers, ho, ho, and all that.

Rusty
