Paul, all the coolant returns merge near the lower water pump port. I 
use the heater port plumbed to a little cabin heater. I drilled a 1/2" 
hole in the forward side of the lower leg of the water pump, and had a 
welder weld a 1/2" NPT aluminum half-coupler to the leg. You can get 
those from McMaster-Carr. Insert a 1/2" NPT to AN-10 adaptor.

If I were you, I would somehow tap that heater port hole in the engine 
and insert a fitting that adapts it to AN-10. I still have a short 4" 
piece of 5/8" automotive heater hose that adapts that heater port hose 
bung to AN-10, but I would prefer to eliminate the hose altogether. The 
cabin heater lines from the engine to bulkhead AN10 fittings on the 
firewall are braided hose. The heater lines that run all the way forward 
inside my fuselage to a small rad and then return to the firewall are 
5/8" aluminum tubing.
