John,
With the radiator located under my engine, I had a concern with air being trapped in the
radiator, and/or engine block. My approach surely isn't the only solution, but it is simple and
appears to be working (2.5hrs run time on system).
Basically, I copied the system used in my 2000 Chevrolet pickup with the 5.3L V-8, with
aluminum heads. It has a small 5/16" line coming from the top corner of
the return side of the radiator (fat hose is at the bottom of this side tank). This small line goes
directly to the accumulator tank, near the top. The outlet from the bottom of the accumulator
tank T's into the water pump inlet. (My 20B pump had a fitting already installed on the inlet.)
The only radiator cap on the system is on the accumulator/burp tank, although I do have a
small burp plug on top of the thermostat housing, but no thermostat. There is a 1/2 gallon plastic
overflow catch bottle connected to the accumulator tank.
I purchased the accumulator/burp tank from Pegasus Racing.
